Ingredients:
For the Cake:
- 2 ½ cups all-purpose flour
- 2 ½ teaspoons baking powder
- ½ teaspoon salt
- ¾ cup unsalted butter, softened
- 2 cups granulated sugar
- 4 large eggs
- 1 tablespoon vanilla extract
- 1 cup milk
- 1 cup fresh raspberries
For the Raspberry Buttercream:
- 1 cup fresh raspberries (or frozen, thawed)
- 1 ½ cups unsalted butter, softened
- 4 cups powdered sugar
- 1 teaspoon vanilla extract
- Pinch of salt
Instructions:
- Preheat your oven to 350 degrees Fahrenheit. Grease and flour three 8-inch round cake pans.
- In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
- In a large bowl, cream the softened butter and granulated sugar together until light and fluffy. Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.
- Gradually add the dry ingredients to the butter mixture, alternating with the milk, and mix until just combined. Fold in the raspberries.
- Divide the batter evenly among the prepared cake pans and smooth the tops.
- Bake for 25 to 30 minutes or until a toothpick inserted in the center comes out clean. Allow the cakes to cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
- In a blender or food processor, puree the fresh raspberries until smooth. Strain the puree through a fine-mesh sieve to remove the seeds, if desired.
- In a large bowl, beat the softened butter with an electric mixer until creamy. Gradually add the powdered sugar, mixing until well combined.
- Stir in the raspberry puree, vanilla extract, and a pinch of salt. Beat until the buttercream is light and fluffy. Adjust the consistency with more powdered sugar if needed.
- Once the cakes are completely cool, place one layer on a serving platter. Spread a layer of raspberry buttercream on top.
- Place the second layer of cake on top and repeat the process. Add the final layer of cake on top.
- Use the remaining raspberry buttercream to frost the top and sides of the cake as desired.
- Decorate the cake with fresh raspberries or additional toppings if desired. Slice and serve.
