Preheat your oven to 350°F. Grease and flour the cake pans well. This helps prevent sticking. Set the pans aside while you prepare the batter.

In a large bowl, add flour, baking powder and salt. Whisk gently until mixed. This step helps the cake bake evenly and rise properly.

Add butter and sugar to another bowl. Beat until light and fluffy. This takes about three minutes. This step adds air for a soft cake.

Add egg whites slowly while mixing. Beat well after each addition. This keeps the batter smooth and light. Do not rush this step.

Mix in almond extract and vanilla extract. Stir gently until combined. These flavors give the cake its classic wedding taste.

Add dry ingredients in parts. Alternate with milk and sour cream. Mix on low speed. Stop mixing once the batter looks smooth.

Pour batter evenly into prepared pans. Place pans in the oven. Bake for thirty to thirty-five minutes. The cake is done when a toothpick comes out clean.

Remove cakes from the oven. Let them cool in pans for ten minutes. Transfer to a cooling rack. Cool fully before frosting.
