A Well Stocked Pantry
Keeping a selection of reliable baking staples on hand means you can pull together an impressive dessert without a long ingredient list.

Fresh raspberries add texture and moisture, while a simple dairy-free chocolate buttercream finishes the cake with creamy richness. The components are straightforward, approachable, and forgiving for home bakers.
Gluten Free Raspberry Cake with Chocolate Buttercream: It’s All About the Slice
When you cut into this cake, the interior reveals pockets of ruby-colored raspberries that look festive and taste bright. The raspberry pieces give each slice bursts of juicy flavor and extra moisture, so the crumb stays tender. The dairy-free chocolate buttercream is made with plant-based butter, powdered sugar, cocoa powder, and vanilla for a classic chocolate finish that pairs beautifully with berry flavors.
This version keeps the process simple: mix the cake mix with raspberry gelatin, fold in fresh raspberries, bake, cool, and frost. Whether you’re serving family, friends, or guests, the result is a striking dessert that’s surprisingly easy to prepare.

Equipment
- 2 mixing bowls
- 8-inch round cake pan
- Offset spatula or butter knife
Ingredients
Raspberry Cake
- 1 box gluten-free white or yellow cake mix
- 1 box raspberry-flavored gelatin
- 2 cups fresh raspberries, plus extra for topping
- Wet ingredients called for on the boxed cake mix (eggs, oil, water or substitutes)
Chocolate Buttercream
- 1 cup dairy-free butter (softened)
- 3 1/2 cups powdered sugar, sifted
- 3/4 cup cocoa powder, sifted
- 2 tsp vanilla extract
- 2–4 tbsp non-dairy milk, if needed to thin the frosting
Instructions
Raspberry Cake
- Preheat the oven to the temperature recommended on your gluten-free cake mix package. Prepare an 8-inch round cake pan by greasing and lining the bottom if desired.
- In a large mixing bowl, combine the dry cake mix and the raspberry gelatin powder until evenly distributed.
- Add the wet ingredients specified on the cake mix box (eggs, oil, water or appropriate substitutes) and mix until smooth, following the package directions for mixing time and consistency.
- Gently fold the fresh raspberries into the batter, taking care not to crush them so the cake retains bright fruit pieces.
- Pour the batter into the prepared pan and bake according to the cake mix instructions. Baking time may vary slightly with raspberries added; test for doneness with a toothpick—avoid areas with fruit when testing.
- Allow the cake to cool in the pan for 10–15 minutes, then transfer to a wire rack to cool completely before frosting.
Chocolate Buttercream
- In a mixing bowl, beat the softened dairy-free butter until smooth. Gradually add the sifted powdered sugar and cocoa powder, mixing on low speed until incorporated.
- Add the vanilla extract and continue to beat until the frosting is creamy. If the frosting is too thick, add non-dairy milk one tablespoon at a time until you reach the desired spreading consistency.
- Using an offset spatula or butter knife, spread the chocolate buttercream evenly over the cooled cake.
- Top with additional fresh raspberries for garnish. Slice and enjoy.
Tips, Variations, and Storage
- Substitutions: If fresh raspberries are out of season, thawed frozen raspberries can work—toss them in a little flour or gluten-free starch before folding in to reduce bleeding.
- Make-ahead: The cake layers can be baked a day ahead and wrapped tightly in plastic wrap, stored at room temperature. Frost just before serving for best texture.
- Storage: Store leftover cake in an airtight container in the refrigerator for up to 4 days. Bring to room temperature before serving for best flavor.
- Serving suggestion: Serve with a dollop of non-dairy whipped cream or a scoop of vanilla dairy-free ice cream to complement the chocolate and raspberry pairing.
