Ingredients
For the Cake:
- 2 cups all-purpose flour
- 1 ½ cups granulated sugar
- ½ cup unsalted butter, softened
- 1 cup fresh blackberries (or frozen, thawed)
- ¾ cup buttermilk
- 2 large eggs
- 2 tsp baking powder
- ½ tsp baking soda
- ¼ tsp salt
- 1 tsp vanilla extract
- Zest of 1 lemon (optional, for extra zing)
For the Frosting:
- 8 oz cream cheese, softened
- ½ cup unsalted butter, softened
- 3 cups powdered sugar
- ½ cup fresh blackberries (for puree)
- 1 tsp vanilla extract
For Garnish (Optional):
- Fresh blackberries
- Lemon zest or mint leaves
Step-by-Step Instructions
- Preheat and Prep
Preheat your oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper. This makes popping the cakes out a breeze. - Mix Dry Ingredients
In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set this aside for now. - Cream Butter and Sugar
In a large bowl, beat the softened butter and granulated sugar with a mixer until light and fluffy, about 2-3 minutes. It should look creamy and pale. - Add Eggs and Vanilla
Beat in the eggs one at a time, then add the vanilla extract and lemon zest (if using). Mix until everything’s combined. - Combine Wet and Dry
Alternate adding the dry ingredients and buttermilk to the butter mixture, starting and ending with the dry. Mix just until combined—don’t overdo it, or the cake might get dense. - Fold in Blackberries
Gently fold in the blackberries with a spatula. If they break a bit, that’s okay; it adds to the cake’s pretty purple swirls. - Bake
Divide the batter evenly between the pans. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely. - Make the Frosting
Puree the blackberries in a blender, then strain to remove seeds. Beat the cream cheese and butter until smooth. Gradually add powdered sugar, then mix in the blackberry puree and vanilla. Adjust with more sugar if it’s too thin. - Assemble the Cake
Place one cake layer on a plate, spread a layer of frosting, then add the second layer. Frost the top and sides. Decorate with fresh blackberries or garnishes if you’re feeling fancy. - Chill and Serve
Pop the cake in the fridge for 30 minutes to set the frosting. Slice and enjoy!

Pro Cooking Tips
- Room Temperature Ingredients: Make sure your butter, eggs, and cream cheese are at room temp for a smoother batter and frosting.
- Don’t Overmix: Overmixing the batter can make the cake tough. Stir just until everything’s combined.
- Fresh vs. Frozen Berries: Fresh blackberries are ideal, but frozen work too. Just thaw and pat them dry to avoid extra moisture.
- Test for Doneness: Ovens vary, so check the cake a few minutes early. A clean toothpick is your best friend.
- Frosting Consistency: If the frosting is too runny, add more powdered sugar, a tablespoon at a time.
Variations
- Blackberry Lemon Cake: Add 2 tbsp lemon juice to the batter and frosting for a citrusy kick.
- Chocolate Blackberry Cake: Swap ¼ cup flour for cocoa powder and add chocolate chips for a decadent twist.
- Gluten-Free Option: Use a 1:1 gluten-free flour blend instead of all-purpose flour.
- Cupcakes: Pour batter into a muffin tin and bake for 18-22 minutes for cute blackberry cupcakes.
Storage Suggestions
- Room Temperature: Store the frosted cake in an airtight container at room temp for up to 1 day.
- Fridge: Keep it in the fridge for up to 5 days. Let it sit out for 20 minutes before serving to soften.
- Freezer: Wrap unfrosted cake layers tightly in plastic wrap and freeze for up to 3 months. Thaw overnight in the fridge before frosting.
How to Serve

A hot cup of coffee or iced tea complements the sweet-tart flavors beautifully.
