Instructions
- Make the Cake:
Preheat the oven to 350°F (177°C). Line four 6-inch round cake pans with parchment paper and lightly coat with nonstick spray.
In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment, cream the butter and sugar on medium speed until light and fluffy. Add the eggs one at a time, mixing well after each addition and scraping down the bowl as needed. Mix in the sour cream, vanilla extract, and vinegar until fully incorporated.
Add the dry ingredients to the wet mixture and mix until just combined. In a small bowl, whisk the food coloring into the buttermilk, then pour it into the batter and mix until fully blended. Scrape the sides and bottom of the bowl as needed to ensure everything is well incorporated.
Divide the batter evenly among the prepared pans. Bake for 25–27 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely. - Make the Frosting:
In the bowl of a stand mixer with the paddle attachment, beat the butter, cream cheese, vanilla, and almond extract on medium-high speed until smooth and creamy, about 2–4 minutes.
Gradually add the powdered sugar, one cup at a time, beating until the frosting is thick, fluffy, and spreadable.
- To Assemble:
Level the tops of the cakes using a serrated knife or cake leveler to create flat layers. Crumble the trimmed pieces into fine crumbs and set aside.
Place the first cake layer on a cake stand or serving plate. Spread a generous layer of cream cheese frosting on top and gently press a handful of fresh blueberries into the frosting.
Repeat with the remaining layers, frosting, and blueberries.
Frost the top and sides of the cake with the remaining cream cheese frosting. Press the reserved cake crumbs onto the sides of the cake to coat. For a decorative finish, pipe rosettes around the top edge, if desired.
Keep the cake covered and refrigerated until ready to serve.
