Posted May 03, 2024, Updated Sep 11, 2024 We have a big family, which means we’re always celebrating something. And the older our kids get, the more friends they want to invite over and the more cake they can eat! So, I took our famous from-scratch chocolate cake recipe and tweaked it to make this chocolate sheet cake recipe. I love sheet cakes because you don’t have to fuss with layers. Simply bake the chocolate sheet cake it in a giant sheet cake pan, then slather the top with frosting and spruce it up with some mini chocolate chips or sprinkles and you have yourself a delicious cake with very little effort! Plus, this chocolate sheet cake is absolutely delicious. It’s supremely moist, intensely chocolate and completely irresistible – especially when it’s frosted with homemade chocolate buttercream.
Chocolate Sheet Cake: Ingredients & Substitutions
All-purpose flour. Cake flour can be used in place of all-purpose flour. Granulated sugar. I suggest white sugar or organic cane sugar for the best results. Unsweetened cocoa powder. Choose your favorite variety. For an extra-dark cake use dark cocoa powder. Espresso powder. I always have espresso powder on hand to make chocolate desserts. It’s worth purchasing if you love baking and it lasts a long time. You can substitute instant coffee if you must. Salted butter. unsalted butter works well too. Sour cream. Full-fat, plain Greek yogurt can be used in place of sour cream. I recommend using full-fat ingredients for the richest, most moist chocolate sheet cake. Whole milk. I suggest using full-fat whole milk in this recipe. You can substitute half and half if desired. Vanilla extract. You can switch up the extract and use almond, peppermint, orange, etc. if you prefer a flavored chocolate cake. Mini chocolate chips. These are a must. Regular-sized chocolate chips sink to the bottom of the cake while baking. Be sure to use mini chips for the best results.
How to Make Chocolate Sheet Cake
We’ll walk through this chocolate sheet cake recipe step-by-step. Watch the video for further guidance. Begin by preheating the oven to 350 degrees F and lining a 18 x13” sheet cake pan with parchment paper. Then, combine the flour, cocoa powder, baking soda, baking powder, sea salt and espresso powder in a medium bowl and set the dry ingredients aside. Then, whisk together the melted butter, sugar eggs, sour cream, milk and vanilla in a large bowl until the mixture is smooth. Next, add the dry ingredients to the wet ingredients and stir until combined. Fold in the mini chocolate chips until evenly distributed throughout the batter. Then, pour the chocolate sheet cake batter into the prepared sheet cake pan (this is my favorite because it has a lid for easy transport). Bake the chocolate sheet cake in the preheated oven for 35-40 minutes, or until a toothpick inserted in the center of the cakes comes out clean or with a few moist crumbs. Once baking is complete, place cake pan on a wire cooling rack to cool to room temperature (this takes about 1 hour. Once cool, you can either lift the cake out of the pan and transfer it to a rectangular serving plate, or leave it in the pan and frost. Let the cake cool completely before frosting with chocolate buttercream frosting (or your favorite frosting)! Let the cake set until the frosting is hardened before serving – I usually put it in the refrigerator to set.
Serve
Cut chocolate sheet cake into pieces and serve. You can put the lid on the cake and chill it overnight if desired. I prefer to serve this cake slightly chilled or at room temperature.

Store leftovers in an airtight container in the refrigeartor for up to 5 days.
Freeze
Or, you can freeze this chocolate sheet cake in two ways: Thaw overnight in the refrigerator before serving.
