Preparation Steps

• Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
• In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
• In a large bowl, cream the butter and sugar together until light and fluffy. Add eggs one at a time, beating well after each addition. Stir in vanilla extract.
• Add flour mixture to the butter mixture alternately with milk, beginning and ending with flour mixture. Stir in sour cream until just combined.
• Divide batter evenly between the prepared pans. Bake for 35-40 minutes or until a toothpick inserted into the center comes out clean.
• Let cakes cool in the pans for 10 minutes, then turn out onto wire racks to cool completely.
• For the frosting, beat together powdered sugar, softened butter, milk, vanilla extract, and a pinch of salt until smooth and creamy. Add more milk if needed to reach desired consistency.
• Once cakes are cooled, spread frosting between layers and over the top and sides of the cake.
