Tips
Room temperature ingredients mix more easily and create a smoother batter, so take eggs and buttermilk out 30-60 minutes before baking.
The vinegar and baking soda reaction creates extra lift and tenderness, but add vinegar last and mix gently to preserve the reaction.
Test doneness with a toothpick and look for cakes that slightly pull away from pan edges for perfectly baked layers.
