This cake takes a while to prepare, but it is well worth it! I pour cake batter into a sheet pan but it's also great done as a 2-layer cake.

Recipe Instructions
Step 1
Preheat oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking pan.
Step 2
Blend cake mix, 1 cup milk, 1/2 cup butter, eggs, and 2 tablespoons vanilla extract in a blender until batter is smooth, about 3 minutes. Pour batter into the prepared pan.
Step 3
Bake in the preheated oven until a toothpick inserted in the center of the cake comes out clean, about 30 minutes.
Step 4
Heat 1/2 cup butter, light brown sugar, and dark brown sugar in a saucepan; bring to a boil. Add 1/4 cup milk and 1 teaspoon vanilla extract and return to a boil. Remove saucepan from heat and spoon confectioners' sugar, about 2 tablespoons at a time, into mixture using a wooden spoon, stirring after each addition until frosting is smooth. Spread frosting over cake.
