Vanilla Birthday Cake (Print Version)

# Ingredients:

01 - ¾ cup (170g, 6oz) cold unsalted butter.
02 - 5 egg whites, room temperature.
03 - 1 cup (8floz/227ml) whole milk or buttermilk with full fat.
04 - 1 whole egg, room temperature.
05 - 4 teaspoons baking powder.
06 - 2 cups (453g/16oz) white sugar.
07 - ½ teaspoon table salt.
08 - 2 1/4 teaspoons vanilla extract (pure).
09 - 3 cups (425g/15oz) cake flour, sifted beforehand.
10 - Vanilla frosting for topping.

# Instructions:

01 - Preheat oven to 350°F/180°C, then butter and line three 6-inch pans with parchment on the bottom.
02 - In a large container, whisk together the egg whites, whole egg, vanilla extract, and milk. Leave it for now.
03 - Use the paddle attachment on your electric mixer at a low speed. Combine the dry ingredients and mix for about a minute before adding the cold butter. Keep mixing until you get a crumbly texture.
04 - Pour the wet mix into the dry ingredients in two portions. Scrape the sides and bottom in between and after adding. Mix until fluffy and light.
05 - Evenly pour the batter into the pans you prepped. Bake for 25-35 minutes, checking with a tester in the center—few crumbs should stick.
06 - Cool the cakes in their pans on racks for about 20 minutes before pulling them out.
07 - Cut uneven tops off the cake layers. Stack with frosting between each layer. Cover the cake with a thin layer of frosting, chill for 30 minutes, then finish with a top coat. Add sprinkles for flair.

# Notes:

01 - Scoop flour portions of 5oz directly into the measuring cup.
02 - You can keep it on the counter for 2 days, refrigerate for 5, or freeze for up to 2 months.
03 - Set the cake out for half an hour to reach room temperature before serving it.
