What Are Jammie Dodger Blondies?
Jammie Dodger Blondies transform the beloved British biscuit into an indulgent bar dessert that captures all the nostalgic flavors we adore. These treats feature a rich vanilla blondie base that mimics the buttery shortbread texture of traditional Jammie Dodgers while maintaining that signature jam center we all crave.
Our version elevates the classic cookie concept by creating thick chewy bars with a golden exterior and tender interior. The blondie batter provides a luxurious foundation that carries hints of vanilla and brown butter notes reminiscent of the original biscuit’s flavor profile.
Raspberry jam creates the iconic red center that makes Jammie Dodgers instantly recognizable. We swirl generous amounts of tangy jam throughout the batter to ensure every bite delivers that perfect balance of sweet and tart flavors that defines the original treat.
The texture sets these blondies apart from their cookie counterpart. While traditional Jammie Dodgers offer a crisp snap our blondie version provides a satisfying chew with slightly crispy edges that give way to a gooey center packed with jam pockets.
These bars offer versatility that extends beyond their British inspiration. We can serve them warm with vanilla ice cream for an elevated dessert or pack them for picnics and lunchboxes as a portable sweet treat that travels well without crumbling.

The 9×9 inch baking tin creates the ideal thickness for our blondies, ensuring they maintain that perfect balance between crispy edges and gooey centers. Using parchment paper eliminates sticking issues and makes removing the blondies effortless once they’ve cooled. An electric mixer significantly reduces mixing time and creates a smoother batter, though a sturdy whisk works well for those preferring manual mixing.
We emphasize having a wire cooling rack ready, as proper cooling prevents soggy bottoms and allows the jam to set properly. The refrigeration step proves crucial for achieving the signature dense, fudgy texture that makes these blondies irresistible.
Instructions
Creating these indulgent Jammie Dodger Blondies requires careful attention to each step to achieve the perfect balance of textures and flavors. Follow our detailed process to transform simple ingredients into this irresistible British-inspired treat.
Prep the Pan and Oven
We begin by preheating our oven to 180°C (350°F) for conventional ovens or 160°C (325°F) for fan-assisted models. Line our 9×9-inch square baking tin with parchment paper and grease it thoroughly to prevent sticking. The proper temperature ensures even baking while the lined tin makes removal effortless once cooled.
Make the Blondie Batter
Our blondie base starts with combining 200g melted unsalted butter with 125g white granulated sugar and 125g light brown sugar until the mixture becomes completely smooth. Beat in 3 medium eggs one at a time until well incorporated throughout the mixture. Gradually stir in 275g plain flour and 1 tbsp cornflour (if using) until just combined without overmixing. Fold in 150g white chocolate chips evenly throughout the batter to create pockets of sweetness in every bite.
Create the Jam Layer
We distribute 200g raspberry jam across the blondie batter by spooning it in generous blobs throughout the surface. Gently swirl the jam into the batter using a knife or skewer to create beautiful marbled patterns. The key is light swirling to maintain distinct jam pockets rather than fully incorporating it into the batter.
Assemble the Blondies
Place 16 Jammie Dodgers evenly across the top of our prepared batter in a 4×4 grid pattern. Press each biscuit gently into the surface so they sit flush with the batter but remain visible on top. The biscuits will create individual portions while adding the authentic Jammie Dodger flavor and texture contrast.
Bake to Perfection
Bake our assembled blondies for 25-30 minutes until they develop a golden exterior with a slight wobble remaining in the center. The edges should appear set while the middle maintains a gentle jiggle when lightly shaken. Allow the blondies to cool completely in the tin before refrigerating for at least 3 hours to achieve the signature dense and fudgy texture that makes these treats irresistible.
Directions for Perfect Results
Achieving bakery-quality Jammie Dodger Blondies requires attention to a few crucial details that make the difference between good and exceptional results. We’ve gathered our most effective techniques to ensure your blondies turn out perfectly every time.
Testing for Doneness
The key to perfect blondies lies in recognizing when they’re properly baked without overdoing them. We recommend checking for a slight wobble in the center when you gently shake the pan – this indicates the ideal texture balance between set edges and a fudgy interior.
Insert a toothpick into the center of the blondies about 2 inches away from any jam swirl. The toothpick should come out with a few moist crumbs clinging to it rather than completely clean. Completely clean means overbaked, while too much wet batter indicates more time is needed.
Watch for visual cues as the blondies approach doneness. The edges should appear set and lightly golden, while the surface develops a slight matte finish. The Jammie Dodger biscuits on top will deepen in color but shouldn’t become dark brown.
Cooling and Cutting Tips
Proper cooling transforms these blondies from good to extraordinary by developing their signature fudgy texture. Allow the blondies to cool in the tin for at least 30 minutes at room temperature before attempting to remove them.
Transfer the entire tin to the refrigerator for a minimum of 3 hours or overnight for best results. This chilling period firms up the texture and makes clean cutting possible while improving the rich, dense consistency we’re after.
Use a sharp knife dipped in warm water and wiped clean between cuts for neat squares. Score the surface lightly before making full cuts to prevent the jam from dragging across the surface. Cut straight down with confidence rather than sawing back and forth to maintain clean edges.
Store cut blondies in an airtight container in the refrigerator where they’ll maintain their perfect texture for up to one week. Bring to room temperature for 15-20 minutes before serving if you prefer a softer bite.
Make-Ahead Instructions
These delicious Jammie Dodger blondies offer excellent make-ahead flexibility for busy schedules and special events. We recommend baking them a day in advance since they maintain their perfect texture and flavor when properly stored.
Allow the blondies to cool completely in the tin for 15 minutes after removing them from the oven. This initial cooling period prevents the bottom from becoming soggy while maintaining the ideal fudgy consistency we want. Transfer the blondies to a wire rack to finish cooling completely before cutting or storing.
For optimal texture development, we suggest refrigerating the blondies for at least 3 hours before serving. This chilling time allows the jam to set properly and creates that signature dense, chewy texture that makes these blondies irresistible. The white chocolate chips also firm up during refrigeration, providing delightful pockets of sweetness throughout each bite.
Store the finished blondies in an airtight container for up to 3 days at room temperature. They actually improve in flavor after the first day as the jam and blondie base meld together beautifully. We find that wrapping individual squares in plastic wrap makes them perfect for packed lunches or on-the-go treats.
These blondies freeze exceptionally well for longer storage needs. Wrap individual portions in plastic wrap, then place them in a freezer-safe container for up to 3 months. Thaw frozen blondies overnight in the refrigerator, then bring them to room temperature before serving for the best eating experience.
Storage Tips
After baking our delicious Jammie Dodger blondies, proper storage ensures they maintain their perfect chewy texture and irresistible flavor. We recommend following exact cooling and storage guidelines to achieve the best results.
Immediate Cooling Process
Remove the blondies from the oven when they still show a slight wobble in the center. Allow them to cool in the baking tin for 10 to 15 minutes before transferring to prevent overcooking along the edges. This timing prevents the bottom from becoming too firm while maintaining the signature gooey center.
Refrigeration for Optimal Texture
Transfer the cooled blondies to the refrigerator for at least 3 hours before cutting and serving. This chilling period transforms the texture into the perfect fudge-like consistency that makes these treats so addictive. The jam sets properly during refrigeration, creating distinct pockets of flavor throughout each square.
Short-Term Storage Guidelines
Store the cut blondies in an airtight container at room temperature for up to 3 days. Layer parchment paper between stacked pieces to prevent sticking. The flavors actually improve over time as the jam and blondie base meld together, creating an even more cohesive taste experience.
Freezing for Long-Term Storage
Wrap cooled blondies tightly in plastic wrap or aluminum foil before placing in freezer-safe containers. Our blondies freeze beautifully for up to 3 months without losing their delightful texture or flavor. Thaw individual portions at room temperature for 30 minutes when ready to enjoy, or remove larger portions the night before serving.
Cutting and Serving Tips
Use a sharp knife dipped in warm water between cuts to achieve clean, professional-looking squares. Wipe the knife clean after each cut to prevent jam from dragging across the surface. This technique ensures each piece maintains its beautiful swirled appearance and neat edges.
Serving Suggestions
We love how versatile these Jammie Dodger blondies are when it comes to presentation and pairing options. Fresh fruit creates a beautiful contrast to the rich sweetness of our blondies. Strawberries and raspberries work particularly well since their tartness balances the sugary jam swirls perfectly.
For an indulgent dessert experience, we recommend serving warm blondies with a generous scoop of vanilla ice cream and a drizzle of caramel sauce. The temperature contrast between the warm blondie and cold ice cream creates an irresistible combination that guests always remember.
Creating dessert parfaits offers another elegant presentation option. We layer cut blondies in clear jars with whipped cream and caramel sauce for a restaurant-quality dessert that showcases the beautiful jam swirls. This method works especially well for dinner parties since you can prepare the parfaits ahead of time.
Our favorite casual serving suggestion pairs these blondies with a steaming cup of coffee or traditional British tea. The rich flavors complement both beverages beautifully, making them perfect for afternoon tea or morning coffee breaks.
Adding edible flowers or fresh mint sprigs transforms these treats into an elegant dessert worthy of special occasions. We simply place a few petals or leaves on top of each blondie square for instant visual appeal.
Extra texture comes from sprinkling crushed Jammie Dodger biscuits over the blondies just before serving. This technique reinforces the original biscuit flavor while adding a satisfying crunch that contrasts with the chewy base.
Homemade glaze or buttercream frosting elevates these blondies to bakery-level sophistication. We drizzle the glaze while the blondies are slightly warm so it sets with an attractive glossy finish that highlights the jam swirls beneath.
Recipe Variations
We love experimenting with different flavors and textures to create unique versions of these beloved blondies. These variations allow you to customize the recipe based on your preferences and available ingredients.
Different Jam Flavors
Raspberry jam remains our top choice for authentic Jammie Dodger flavor, delivering the perfect balance of sweet and tart notes that complement the rich blondie base. The traditional raspberry provides that classic British biscuit taste we all remember.
Strawberry jam offers a gentler alternative with its naturally sweeter profile and milder acidity. This option works beautifully for those who prefer less tartness while maintaining the fruity essence that makes these blondies special.
We encourage adventurous baking with blueberry jam for a deeper berry flavor or apricot jam for a sophisticated floral note. These alternative flavors create exciting new taste combinations while preserving the signature jam swirl appearance.
Add-In Options
White chocolate chips enhance the blondies with creamy sweetness and create delightful pockets of richness throughout each bite. We recommend using 150 grams for optimal distribution without overwhelming the base flavor.
Mini Jammie Dodgers embedded directly into the batter transform these treats into a true celebration of the original biscuit. Press 8-10 mini biscuits into the surface before baking for visual appeal and authentic texture contrast.
Consider incorporating chopped nuts like toasted almonds or hazelnuts for added crunch and sophisticated flavor depth. Dried fruits such as cranberries or chopped dried strawberries complement the jam beautifully while providing chewy texture variation.
Dark chocolate chips or milk chocolate chunks create indulgent alternatives to white chocolate, offering richer cocoa notes that pair exceptionally well with raspberry or strawberry jam swirls.
Troubleshooting Common Issues
Even experienced bakers sometimes face challenges when making Jammie Dodger blondies. We’ve identified the most common problems and their answers to help you achieve perfect results every time.
Dry or Crumbly Texture
Overcooking stands as the primary culprit behind dry blondies. We recommend checking your blondies at the 25-minute mark and looking for a slight wobble in the center rather than complete firmness. The edges should appear golden and set while the middle maintains some movement when gently shaken.
Temperature accuracy plays a crucial role in preventing dryness. Using an oven thermometer helps verify that your oven reaches the correct 160°C to 180°C range. Many home ovens run hot or cold which can dramatically affect baking times and texture.
Ingredient ratios also impact moisture levels. Adding too much flour creates dense crumbly blondies while insufficient butter leads to dryness. We suggest measuring flour by weight rather than volume for consistent results every time.
| Common Causes | Answers |
|---|---|
| Overcooking | Check at 25 minutes for slight wobble |
| Incorrect oven temperature | Use oven thermometer to verify heat |
| Too much flour | Measure by weight (275g) |
| Overmixing batter | Fold ingredients until just combined |
Wet or Undercooked Center
Underbaking creates blondies that remain too wet and fail to set properly. We recommend extending baking time by 5-minute increments until the center shows only minimal wobble. The toothpick test should reveal moist crumbs rather than wet batter.
Incorrect wet-to-dry ingredient ratios can result in overly soft blondies. Double-check that you’re using the specified amounts of butter and eggs against the flour measurement. Too much jam can also create excess moisture that prevents proper setting.
Cooling techniques significantly impact final texture. We always recommend cooling blondies completely in the tin before transferring to prevent structural collapse. Refrigerating for at least 3 hours after cooling helps firm the texture and makes cutting much easier.
Uneven Baking
Hot spots in your oven can create unevenly baked blondies with some areas overdone while others remain underbaked. Rotating the pan halfway through baking helps ensure even browning and consistent texture throughout.
Pan preparation affects heat distribution significantly. We line our 9×9 inch tin with parchment paper and lightly grease the sides to prevent sticking while promoting even heat transfer. Dark colored pans may require reducing temperature by 10°C to prevent over-browning.
Jam Distribution Problems
Swirling technique determines how evenly jam distributes throughout your blondies. We spoon dollops of raspberry jam across the surface then use a knife tip to create gentle swirls. Over-mixing incorporates too much jam into the batter while under-mixing creates large jam pockets.
Jam consistency impacts distribution success. Room temperature jam spreads more easily than cold jam straight from the refrigerator. We recommend letting jam sit at room temperature for 30 minutes before using for optimal swirling results.
