Instructions
Cake
- Preheat oven to 350°
- Grease and flour two 9-inch (23cm) round cake pans or line them with parchment paper.
- In a medium bowl, sift together the flour, baking powder, baking soda, and salt. Set aside.
- In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
- Add the eggs one at a time, beating well after each addition.
- Stir in the vanilla extract.
- Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients.
- Mix until just combined.
- Gently fold in the fresh blackberries until evenly distributed throughout the batter.
- Divide the cake batter evenly between the prepared cake pans.
- Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center of the cakes comes out clean.
- Remove the cakes from the oven and let them cool in the pans for 10 minutes before transferring them to wire racks to cool completely.
Frosting
- In a large mixing bowl, beat the softened butter until smooth and creamy.
- Gradually add the sifted powdered sugar, blackberry puree, vanilla extract, and salt, beating until smooth and creamy.
- Adjust the consistency by adding more powdered sugar if too thin, or more blackberry puree if too thick.
Assembly
- Once the cakes are completely cool, place one cake layer on a serving plate or cake stand.
- Spread a layer of blackberry buttercream frosting evenly over the top of the first cake layer.
- Place the second cake layer on top and frost the top and sides of the cake with the remaining blackberry buttercream frosting(usually 3 or 4 cake layers are used).
Decorate (Optional)
- Garnish the top of the cake with fresh blackberries, lemon zest, and mint leaves for a beautiful presentation.
