Instructions

Preheat the oven to 325°F. Spray a 9×13-inch baking dish with nonstick cooking spray or line it with parchment paper.
In a large bowl, whisk together the cake flour, baking powder, and salt. Set aside.
In a stand mixer bowl, cream the butter, sugar, vanilla extract, and almond extract until light and fluffy, about 5 minutes. Scrape down the bowl as necessary.
With the mixer on low, add the egg whites one at a time, beating well and scraping the bowl after each addition.
Add the dry ingredients in three parts, alternating with the milk, mixing on low speed just until combined. Scrape the bowl one last time.
Pour the batter into the baking dish and spread evenly. Tap the pan on the counter gently to release air bubbles.
Bake for 50 to 55 minutes, until a toothpick comes out with a few moist crumbs. Start checking at 45 minutes.
Let the cake cool completely in the pan on a wire rack before frosting.

Notes

For a richer flavor, use pure vanilla extract and a good quality almond extract.
Ensure your eggs and milk are at room temperature to help the batter mix evenly.
Allow the cake to cool completely before frosting to prevent the icing from melting.
