BLUEBERRY LEMON CAKE WITH BUTTERCREAM FROSTING

Steps:

• Preheat the oven to 350 degrees F (175 degrees C). Lightly butter and sugar three 8-inch round nonstick cake pans.
• Sift flour, baking powder, baking soda, and salt together in a medium mixing bowl.
• Cream sugar and butter together in a large bowl using an electric mixer. Mix in lemon juice until smooth. Add eggs 1 at a time, mixing until fully combined. Alternate adding the flour mixture and buttermilk with the mixer set to the lowest speed. Mix until batter is smooth, scraping the bowl down occasionally. Use a spatula to gently fold in blueberries.
• Fill the prepared cake pans evenly with batter.
• Bake in the preheated oven until a toothpick inserted into the center of each cake comes out clean, 30 to 35 minutes. Let cool completely before removing from the pans, about 30 minutes.
• While cakes are cooling, beat butter for frosting in a large mixing bowl using an electric mixer on medium speed. Reduce speed to low and add confectioners' sugar a little at a time, alternating with splashes of milk and vanilla extract. Mix until frosting is smooth.
• Spread frosting over each of the cooled cake layers and stack; then frost the sides.
