Ingredients

Cake

• 3/4 cup granulated sugar
• 3/4 cup hot water
• 3 cups all-purpose flour
• 1 1/2 teaspoons baking powder
• 1/4 teaspoon baking soda
• 1 1/2 cups granulated sugar
• 2/3 cup butter, softened
• 2 egg yolks
• 2 teaspoons vanilla extract
• 2 egg whites
• 1 1/2 cups finely chopped assorted candy bars
• Browned Butter Frosting
• Coarsely chopped assorted candy bars, such as Hershey's, Mars, Nestle, or other (optional)

Browned Butter Frosting

• 1/2 cup butter
• 6 ounces cream cheese
• 3 tablespoons butter
• 6 1/2 cups sifted confectioners' sugar, divided
• 2 to 3 teaspoons milk

Instructions

1. Grease and lightly flour three 8 x 1 1/2-inch round baking pans or two 9 x 2-inch pans.
2. In a large skillet cook the 3/4 cup sugar over medium-high heat until the sugar just begins to melt. Do not stir. Reduce heat; cook until sugar is golden brown, about 1 to 3 minutes more, stirring mixture constantly.
3. Carefully stir in hot water (syrup will form lumps). Bring mixture to boiling; reduce heat. Continue stirring until mixture is free of lumps. Remove from heat. Pour syrup into a large glass measuring cup. Add additional water to equal 1 3/4 cups liquid. Set aside to cool.
4. Heat oven to 350 degrees F.
5. In a large mixing bowl stir together flour, baking powder and baking soda. Beat together the 1 1/2 cups sugar, the 2/3 cup butter, egg yolks and the vanilla extract with an electric mixer on medium speed for 1 minute or until mixture is smooth.
6. Alternately add flour mixture and sugar syrup to egg yolk mixture, beating on low speed after each addition just until combined. Clean beaters thoroughly.
7. In a medium mixing bowl beat egg whites until stiff peaks form (tips stand straight). Fold into batter. Divide batter into baking pans; spread evenly. Bake for 25 to 30 minutes or until a wooden pick inserted near center comes out clean. Cool in pans on wire rack for 10 minutes. Remove cakes from pans; transfer to wire racks; cool completely. Prepare Browned Butter Frosting.
8. To assemble, spread 1/2 cup Browned Butter Frosting over bottoms of two of the cake layers. Sprinkle each frosted layer with half of the finely chopped candy. Stack these layers on cake plate, frosted sides up. Place the third (8nfrosted) layer on top, rounded side up.
9. Spread remaining frosting on top and sides of cake. Garnish with the coarsely chopped candy bar pieces, if desired.
10. Browned Butter Frosting: In a small saucepan, heat and stir the 1/2 cup butter over low heat until melted. Continue heating until butter turns a nut-brown color. Remove from heat; cool for 5 minutes.
11. In a large mixing bowl beat cream cheese and the 3 tablespoons butter until combined. Beat in about 2 cups of the confectioners' sugar. Beat in the browned butter and vanilla extract. Gradually beat in 4 1/2 more cups sifted confectioners' sugar and milk until frosting is of spreading consistency.
