CHOCOLATE SHEET CAKE

Sheet Cakes are perfect to make for potlucks because the easy cake batter is spread over a large baking pan. This makes it easy to bake, slice, and get lots of pieces from. It’s also wonderfully portable because the rimmed pan will contain the cake even if it gets jostled a little in the car.

This delicious Chocolate Sheet Cake is similar to a classic Texas Sheet Cake. Just like this recipe Texas Sheet Cake is a classic American chocolate cake made in a large pan and frosted. Either recipe will give you an easy, moist dessert. However, there are some key differences between the two.

Chocolate Sheet Cake trio of prep steps: batter in baking dish, baked cake in baking dish, frosted cake in baking dish

One big ingredient in this recipe that you won’t find in our Texas Sheet Cake is brewed coffee. We love adding coffee to chocolate recipes because it adds moisture and the coffee enhances the sweet chocolate flavor for an even more amazing dessert.

Along with the tender cake base, the cake recipe also has a rich, sweet chocolate icing. One of the most important steps to getting this recipe right is to let the cakes cool entirely before you add the frosting. As long as you take that extra time, the frosting will spread easily over the tender chocolate cake.

TIPS FOR MAKING CHOCOLATE SHEET CAKE

  • Prep time: Start by preheating your oven and spraying a rimmed baking sheet or jelly roll pan with cooking spray. If you don’t have cooking spray, you can line the pan with parchment paper instead.
  • Cake batter: Add the granulated sugar, flour, cocoa powder, baking powder, baking soda, and salt to a stand mixer and mix them together on low speed. If you don’t have a stand mixer you can just add the dry ingredients to a mixing bowl and use a hand-held mixer. In a separate bowl whisk together the eggs, milk, oil, and vanilla extract. Once they’re well combined pour them into the flour mixture. Mix on low speed until well combined.
  • Coffee: Turn the mixer off and add the coffee. You can use freshly brewed coffee, hot instant coffee, or replace the coffee with hot water. Stir the coffee in by hand until the cake batter is just combined. You want to stir by hand instead of the mixer to make sure the hot coffee doesn’t splash up and burn you.
  • Bake: Pour the batter into the center of the prepared pan. It should spread out evenly on its own, but you use a spatula to help smooth it out. Bake for 30-35 minutes. The Sheet Cake will be done when a toothpick inserted in the center comes out with moist crumbs on it. If the toothpick comes out with batter still on it, add a few minutes of baking time. Let the cake cool entirely before spreading the frosting over it.
  • Frosting: While the cake cools, add the butter to a medium saucepan over medium heat and whisk in the cocoa powder as it melts. Let the chocolate mixture cool for a few minutes. Then add it to the stand mixer and begin whipping it on medium speed. Add the powdered sugar and milk ⅓ cup at a time alternating between the two. Then finish the frosting by mixing in the vanilla extract. If the frosting is too thick add milk to reach the desired consistency.
  • Serve: Spread the icing over the cooled sheet cake. Slice the cake into square pieces and enjoy.

VARIATIONS ON CHOCOLATE SHEET CAKE

  • Gluten-free: To make a gluten-free sheet cake replace the all-purpose flour in the recipe with a gluten-free alternative. Almond flour, oat flour, coconut flour, or any of your preferred flour substitutes should work.
  • Toppings: After frosting the Chocolate Sheet Cake you can add your favorite dessert toppings to it. Sprinkles, pecans, peanuts, chocolate chips, coconut flakes, or berries would all make nice additions.
  • Dark chocolate: To make a dark chocolate sheet cake replace the cocoa powder in the cake batter and the icing with dark cocoa powder.
    Cupcakes: For easily portable, mini cakes you can pour the batter into lined cupcake trays. Bake until the chocolate cake batter sets. Let the cupcakes cool and then frost them.
