This decadent raspberry chocolate lava cupcake recipe transforms ordinary chocolate cupcakes into something extraordinary with its molten raspberry center that oozes with each bite. The contrast between the rich chocolate cake and the sweet-tart raspberry filling creates a dessert experience that feels both elegant and comforting.
I first made these cupcakes for my daughter's birthday when she requested "something chocolate with berries." The look on her face when she discovered the raspberry surprise inside was priceless, and they've been our celebration go-to ever since.
Ingredients
- All purpose flour: Forms the foundation for these cupcakes providing structure while keeping them tender
- Unsweetened cocoa powder: Delivers deep chocolate flavor, use Dutch processed for more intense color and taste
- Baking soda: Helps the cupcakes rise and creates a lighter texture
- Salt: Enhances all the flavors, especially bringing out the chocolate notes
- Unsalted butter: Adds richness and moisture, look for European style for higher fat content
- Sugar: Sweetens and helps create a tender crumb
- Large eggs: Provide structure and richness, make sure they're room temperature for better incorporation
- Vanilla extract: Adds depth to the chocolate flavor, use pure not imitation
- Buttermilk: Creates tenderness and a slight tang to balance the sweetness
- Boiling water: Blooms the cocoa powder, intensifying the chocolate flavor
- Raspberry preserves: Creates the molten lava center, choose a quality brand with visible fruit pieces
- Fresh raspberries: For garnish, add visual appeal and fresh flavor
- Butter (for buttercream): Creates the silky base for your frosting
- Powdered sugar: Sweetens and stabilizes the frosting
- Raspberry puree: Adds natural color and flavor, strain seeds for a smoother texture
- Dark chocolate shavings: Provide contrast and elevate the presentation
Step-by-Step Instructions
- Prepare Your Oven and Pan:
- Preheat your oven to exactly 350°F ensuring your oven rack is positioned in the center. Line your muffin tin with quality cupcake liners that won't peel away from the cakes as they cool. Dark colored pans may require reducing the temperature by 25 degrees to prevent overbaking.
- Create Your Dry Mixture:
- Whisk the flour, cocoa powder, baking soda, and salt together in a medium bowl until completely combined with no visible cocoa lumps. Whisking rather than sifting incorporates air while ensuring even distribution of leavening agents.
- Cream The Base:
- In a large bowl, beat the softened butter until smooth, about 1 minute, then gradually add sugar and continue beating for 3 full minutes until the mixture is notably lighter in both color and texture. This process incorporates air, creating a tender crumb.
- Add The Wet Ingredients:
- Add eggs one at a time, beating for 30 seconds after each addition to fully incorporate. Mix in vanilla extract until just combined, scraping down the sides of the bowl frequently to ensure everything is evenly mixed.
- Combine Wet and Dry:
- Add one third of your dry ingredients to the butter mixture, beating on low just until combined, then add half the buttermilk and mix. Continue alternating with dry ingredients again, followed by remaining buttermilk, and finishing with the last third of dry ingredients. This method prevents overmixing which would develop gluten and toughen the cupcakes.
- Finish The Batter:
- Carefully pour in the boiling water and stir gently with a spatula until completely incorporated. The batter will appear quite thin, this is normal and will produce moist cupcakes with the perfect texture for surrounding the raspberry filling.
- Create The Lava Effect:
- Fill each cupcake liner exactly halfway with batter, using a cookie scoop for precision. Add a heaping teaspoon of raspberry preserves directly in the center of each without letting it touch the sides of the liner. Top with remaining batter until each cup is three quarters full, allowing space for rising.
- Bake To Perfection:
- Bake for 18 to 22 minutes, checking at the minimum time. Insert a toothpick into the edge of a cupcake, not the center where the preserves are located. When the toothpick comes out clean or with a few moist crumbs, the cupcakes are done. Avoid overbaking, which would dry out the tender cake.
- Prepare The Buttercream:
- Beat room temperature butter for a full 3 minutes until notably lighter in color. Gradually add powdered sugar one half cup at a time, mixing completely between additions. Add the strained raspberry puree, vanilla, and pinch of salt, beating on medium high speed for 5 minutes until extremely light and fluffy. The extended beating time creates the silkiest texture.

The secret to these cupcakes is using high quality raspberry preserves. I discovered this by accident when I splurged on an artisanal jar from our farmers market. The chunks of real fruit created pockets of intense flavor that made all the difference. Now I always keep a special jar just for baking these cupcakes.
Perfect Your Timing
The key to maintaining the molten center is careful baking time. Even one or two minutes of overbaking can turn your lava center into just a raspberry filling. Start checking at 18 minutes even if you need to open the oven door. The cupcakes should look set on top but still have a slight jiggle in the very center. Remember that they will continue cooking slightly after removal from the oven due to residual heat.
Storage Secrets
These cupcakes maintain their wonderful texture and lava center for up to three days when stored properly. Keep them in an airtight container at room temperature rather than refrigerating which would firm up the center and dry out the cake. If you need to prepare further in advance bake the cupcakes and freeze them unfrosted then thaw at room temperature and add the buttercream before serving.
Seasonal Variations
While raspberry creates the classic version this recipe welcomes adaptations based on seasonal fruits. In summer substitute blackberry or strawberry preserves. Fall calls for apple butter with a pinch of cinnamon in the batter. Winter holidays shine with orange marmalade and a touch of Grand Marnier in both the batter and frosting. The technique remains the same only the flavor profile changes with the seasons.
Elegant Presentation
Transform these cupcakes from casual to elegant with thoughtful presentation. Place each cupcake in a paper coffee filter which creates a decorative edge. Pipe the buttercream in a spiral starting from the outside moving inward then top with a single perfect fresh raspberry balanced on a tiny chocolate curl. For special occasions dust the plates with cocoa powder through a doily stencil creating a decorative pattern beneath each cupcake.

Frequently Asked Questions
- → Can I use frozen raspberries instead of fresh for the buttercream?
Yes, frozen raspberries work well for the buttercream. Thaw them completely, then puree and strain to remove seeds before incorporating into the frosting. You may need to adjust the amount of powdered sugar as frozen berries can release more liquid.
- → How do I know when the cupcakes are properly baked?
Test for doneness by inserting a toothpick into the edge of the cupcake (not the center where the raspberry filling is). The toothpick should come out clean or with a few moist crumbs. The centers will remain slightly molten due to the raspberry preserves.
- → Can I make these cupcakes ahead of time?
Yes, you can bake the cupcakes a day ahead and store them in an airtight container at room temperature. The buttercream can also be made ahead and refrigerated. Bring to room temperature and re-whip before frosting. Fully assembled cupcakes are best enjoyed within 2 days.
- → How do I create the raspberry puree for the buttercream?
Blend fresh or thawed frozen raspberries in a food processor until smooth. Strain through a fine-mesh sieve to remove seeds. For 1/4 cup of puree, you'll need approximately 1 cup of fresh raspberries.
- → Can I substitute the raspberry preserves with another flavor?
Absolutely! This recipe works beautifully with other fruit preserves like strawberry, blackberry, or cherry. You can customize the buttercream to match by using the corresponding fruit puree.
- → Why add boiling water to the batter?
Boiling water helps bloom the cocoa powder, intensifying the chocolate flavor and creating a lighter, more tender crumb. It also produces a slightly thinner batter that allows the raspberry filling to remain suspended in the center rather than sinking to the bottom.
