In a large bowl, whisk together flour, baking powder, and salt. Set aside
Cream the butter and sugar together until light and fluffy

Combine the buttermilk and whole milk. Alternately add the dry ingredients and milk mixture to the butter mixture, mixing until just combined
Divide the batter evenly among the prepared pans
Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let cool in pans for ten minutes before transferring to wire racks

Once the cakes are cool, level the tops if needed. Layer with frosting between each cake layer and apply a crumb coat
Refrigerate for 20 minutes, then apply the final coat of frosting and decorate as desired

Notes

For a chocolate version, replace one cup of flour with unsweetened cocoa powder.

If you don't have buttermilk, add one tablespoon of lemon juice or white vinegar to regular milk.
