Dulce de Leche Cake (recipe adapted from sporkorfoon.com
 
This recipe is for a 2-layer cake. For a 3-layer cake (as I made), multiply the cake ingredients by 1.5 and the frosting ingredients by 2 (so you have some leftover for decorating)
Ingredients
For the cake:
  • 2¼ cups cake flour
  • 1 cup 2% milk, at room temperature
  • 6 large egg whites, at room temperature
  • 1 tsp vanilla extract
  • 1¾ cup granulated sugar
  • 4 tsp baking powder
  • 1 tsp salt
  • 12 TBSP butter, softened but still solid
For the frosting:
  • 4 TBSP butter, softened
  • 1 cup packed dark brown sugar
  • ⅓ cup heavy cream
  • 1 TBSP vanilla extract
  • 1 box (4 cups) confectioners sugar
Instructions
For the cake:
  1. Preheat the oven to 350 degrees F. Spread Wilton cake release on the inside the 2 9-inch cake pans
  2. Pour the milk, egg whites, and vanilla into a bowl and mix together with a fork.
  3. Mix the cake flour, sugar, baking powder, and salt in a Kitchenaid mixer until blended.
  4. Add the butter and mix on slow speed until moist crumbs are formed.
  5. Add half the milk mixture and mix on medium speed for 1½ minutes. Add the rest of the milk mixture and mix for 30 seconds more.
  6. Pour the batter evenly in the 2 pans and bake for 20-25 minutes until a knife inserted in the center comes out clean.
For the frosting:
  1. Melt the butter in a saucepan. Then add the sugar and cream and cook on medium heat until the sugar is dissolved.
  2. Pour this into the bowl of a Kitchenaid mixer (or other heatproof bowl) and slowly add the confectioner's sugar until the frosting is a spreadable consistency.
  3. This frosting can dry out easily, so remix and add a little cream if necessary.
