Lego Sheet Cake Recipes

Steps:

• Heat oven to 350°F (325°F for dark or nonstick pan). Grease or spray bottom and sides of 13x9-inch pan.
• Make and bake cake mix as directed on box for 13x9-inch pan. Cool in pan 10 minutes; remove from pan to cooling rack. Cool completely, about 1 hour. Refrigerate or freeze cake about 1 hour or until firm.
• Meanwhile, in small bowl for each color, tint 1 cup frosting red, 1 cup frosting yellow and 2/3 cup frosting blue with food colors. Leave remaining frosting white.
• Using serrated knife, cut rounded dome from top of cake to make flat surface; place cake cut side down. Cut cake crosswise into thirds. Cut one of the thirds in half crosswise to make 2 squares. Place cake pieces on tray.
• To seal in crumbs, frost top and sides of 1 square cake with thin layer of blue frosting and 1 square cake with thin layer of white frosting. Frost 1 rectangular cake with thin layer of yellow frosting and 1 rectangular cake with thin layer of red frosting. Refrigerate or freeze 30 to 60 minutes to set frosting.
• Add final coat of frosting to each cake. Frost 4 marshmallow halves with blue frosting; place in square design on blue cake. Frost 4 marshmallow halves with white frosting; place in square design on white cake. Frost 8 marshmallow halves with yellow frosting; place on yellow cake. Frost 8 marshmallow halves with red frosting; place on red cake. Store loosely covered.

Steps:

• Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a 10x15-inch cake pan.
• Combine butter, water, and cocoa powder for cake in a saucepan over medium heat. Cook until butter has melted and mixture comes to a boil. Remove from the heat and cool slightly.
• Meanwhile, mix flour, sugar, and salt together in a large bowl. Beat buttermilk, eggs, baking soda, and vanilla extract together in a separate bowl.
• Add melted butter mixture to the flour mixture, then add buttermilk-egg mixture and beat until thoroughly combined. Pour into the prepared cake pan.
• Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 20 minutes. Remove cake from the oven and cool on a wire rack for 5 minutes.
• Meanwhile, combine butter, milk, cocoa powder, and vanilla extract for the frosting in a saucepan over medium heat. Stir until butter melts, then stir in powdered sugar. Spread frosting over the warm cake.
