After that, add the dry ingredients to the large bowl with the wet ingredients and thoroughly combine the cake batter. Then, fold in the mini chocolate chips. Lightly spray a baking sheet with oil and evenly spread the batter.

Next, bake the cake. Once the cake is done, remove it from the oven and make the amazing chocolate frosting.

How To Make Chocolate Frosting

To make the chocolate frosting, fill a saucepan with 1-2 inches of water and bring it to a boil. Also, chop the dark chocolate bar so it melts quickly and evenly. Place a heat-resistant bowl on top of the saucepan and reduce the water to a simmer. 

After that, pour the chopped chocolate into the bowl and mix it the entire time so that it doesn’t burn. Make sure to remove the bowl from the stove when there are a few small chunks of chocolate left and finish stirring the chocolate in the bowl on a towel. Then, add the 0 fat Greek yogurt to the bowl with the melted chocolate and combine.

Toppings For Chocolate Sheet Cake

This chocolate cake is delicious as is, but feel free to add toppings! Just make sure to add them after frosting the cake so they stick. Some of our favorite toppings include chopped walnuts, sprinkles, shredded coconut, freeze-dried fruit, and fresh fruit. Also, we like adding some crushed peppermint around the holidays!

Notes & Tips For Chocolate Sheet Cake

What Is Sheet Cake?

Sheet cake gets its name because it is baked on a baking sheet. Sheet cake is rectangular in shape and usually one layer. Also, sheet cake is often topped with frosting. It’s super easy to make and delicious!

The Best Chocolate For Chocolate Cake

For the chocolate frosting, we used 62% semisweet dark chocolate. Milk, dark, white chocolate, or even chocolate with coconut will work well for the frosting. Have fun with it! We don’t recommend going over 62% for dark chocolate because it becomes too intense and bitter. If you want to make the chocolate frosting sugar-free you can use a Lily’s sugar-free chocolate bar. Also, you can make the cake sugar-free by using sugar-free mini chocolate chips. The key is to use a high-quality chocolate bar. We love using two Trader Joe’s chocolate bars that are 1.65 oz each. Also, Ghirardelli and Scharffen Berger chocolate bars work well. We recommend using a large chocolate bar that is around 3-3.5 ounces.

How Long Does Sheet Cake Last In The Fridge?

We love storing our chocolate sheet cake in the refrigerator. Make sure to store the sheet cake in an air-tight container. It will last 3-5 days in the fridge. Then, you can heat it up in the oven when you want to eat it again!

How Long Can Sheet Cake Sit Out?

Sheet cake will last 2-3 days in an airtight container or a cake-keeper in a dry place. Any longer than this may cause the cake to dry out.

How Long To Bake Sheet Cake

This homemade chocolate sheet cake takes 20 minutes to bake at 400 degrees F. Also, this sheet cake is made with a 10x15x1 baking sheet. In addition, make sure to evenly spread the batter in the sheet pan so it cooks evenly. You will know your sheet cake is done when a toothpick comes out clean. 

How To Reheat Sheet Cake

To reheat this sheet cake, wrap it in tinfoil. Then, place it in the oven at 350 degrees F for about 10 minutes. We love doing this so we can enjoy the cake warm!

Ingredients

  • For The Cake
  • 2 CUPS all-purpose flour

  • 5 TBSP of unsweetened cocoa powder

  • 1 TSP baking soda

  • 1/4 TSP salt

  • 3/4 CUP sugar or monk fruit

  • 1 CUP unsweetened applesauce

  • 1 CUP 0-fat Greek yogurt

  • 1 TSP vanilla extract

  • 2 eggs

  • 1/3 CUP mini chocolate chips

  • For The Frosting
  • large chocolate bar (3-3.5 oz)

  • 1/4 CUP 0 fat Greek yogurt

Directions

  • Add the all-purpose flour, unsweetened cocoa powder, baking soda, salt, and monk fruit or sugar to a bowl. Then, thoroughly mix the ingredients.
  • In a large bowl, combine the unsweetened applesauce, 0-fat Greek yogurt, vanilla extract, and eggs. Make sure the ingredients are thoroughly combined, especially the 0-fat Greek yogurt. You don’t want any lumps of yogurt in the batter.
  • Add the dry ingredients to the large bowl with the wet ingredients and combine the batter. Once thoroughly combined, fold in the mini chocolate chips.
  • Lightly spray a 10x15x1 inch baking sheet with oil. Pour the cake batter into the sheet pan. Make sure to evenly spread the batter around the baking sheet so the cake cooks evenly. Bake the cake at 400 degrees F for 20 minutes.
  • Once the cake is done, remove it from the oven and make the delicious chocolate frosting. To make the frosting, fill a saucepan with 1-2 inches of water and bring it to a boil. Also, chop the chocolate bar so it melts quickly and evenly.
  • Once boiling, place a heat-resistant bowl on top of the saucepan and reduce the water to a simmer. Pour the chopped chocolate into the bowl and mix it the entire time so that it doesn’t burn. Also, make sure not to get any water in the chocolate so it doesn’t seize. Remove the bowl from the stove when there are a few small chunks of chocolate left and finish stirring the chocolate in the bowl on a towel. This will assure the chocolate won’t overcook or burn.
  • Add the 1/4 cup of 0-fat Greek yogurt to the bowl with the melted chocolate and thoroughly combine. Next, immediately frost your cake. This chocolate sheet cake is amazing as is, but if you would like to add toppings, add them after you have frosted the cake while it cools so they stick. Cut the cake into 21 pieces and enjoy! This was 3 even horizontal slices and then 7 vertical slices to get 21 pieces.
