Instructions

Preheat oven to 350°F. Grease a 9*13 sheet pan

Combine dry ingredients (flour, baking powder, sugar, and salt) in a mixing bowl *if using a stand mixer, use a paddle attachment not a whisk.

In a separate bowl or large glass measuring cup, whisk vanilla, egg whites, milk, and vegetable oil.

With the mixer on low, add chunks of butter slowly to the dry mix.

Mix until no lumps remain, the mixture will become crumbly

Add 1/3 of the liquid ingredients to the dry ingredients (it will look like a thick brownie batter) scrape down the bowl.

And in another 1/3 or the wet and beat on medium high for 4-5 mins

Scrape the bowl down and add the final 1/3 of the wet ingredients and mix on medium speed for an additional 5 mins.

Pour into prepared cake pan.

Bake for 50 minutes, or until a skewer comes out clean and sides have begun to pull away from the side of the pan.

Allow the cake to cool completely inside the pan. Decorate with buttercream or cream-cheese frosting.

Tips & Tricks (5)

Room Temperature Ingredients for Even Crumb 🌡️
Allow butter, eggs, and milk to reach room temperature before mixing to ensure proper emulsification and a tender, uniform crumb structure throughout the cake.
Cream Butter and Sugar Thoroughly ✨
Beat butter and sugar together for 3-5 minutes until pale and fluffy to incorporate air, which creates a lighter, more delicate cake texture.
Alternate Dry and Wet Ingredients 🔄
Mix flour mixture and milk in alternating batches, starting and ending with dry ingredients, to prevent overmixing and develop a tender crumb.
Use Pure Vanilla Extract for Superior Flavor 🌿
Pure vanilla extract delivers authentic depth compared to imitation; add it after mixing is complete to preserve its delicate aromatic compounds from heat exposure.
Don't Overbake—Check at 25 Minutes ⏱️
Insert a toothpick at 25 minutes; the cake should be set with just a few moist crumbs, as residual heat will continue cooking after removal from the oven.
