Sourdough Chocolate Sheet Cake

“This is a sourdough version of the chocolate sheet cake I had growing up.”

I would love more FREE recipes and tips straight to my IN BOX!

Chocolate sheet cake was a summer staple for me growing up in Iowa! We always served this in the summer with homemade ice cream. It was a cool treat to go with the moist yumminess of the chocolate sheet cake on a hot summer night. This was truly one of my favorite desserts. I even had Mom's recipe memorized.

Prep Time: 20 minutes

Cook Time: 15-20 min

Servings: 1 sheet cake

Ingredients

For the Cake:

180 g very hot water (180ºF) (about 3/4 cup)
226 g unsalted butter, melted (about 1 cup)
35 g cocoa powder (about 1/3 cup, see recipe notes)
240 g all-purpose flour (about 1 3/4 cups)
300 g granulated sugar (about 1 1/2 cups)
6 g baking soda (about 1 teaspoon)
4 g salt (about 1/2 teaspoon)
120 g sourdough discard (about 1/2 cup)
2 large eggs (about 100 grams)
115 g sour cream (about 1/2 cup), (I used Cocojune Pure Coconut Yogurt)
5 g vanilla (about 1 teaspoon)

For the Frosting:

113 g unsalted butter, melted (1/2 cup)
30 g cocoa powder (about 4 Tablespoons)
360 g powdered sugar (about 3 cups, see recipe notes)
90 g milk (about 6 Tablespoons), (I used coconut milk)
4 g vanilla (about 1 teaspoon)
3 g salt (about 1/2 teaspoon)

Preparation Steps

1. Preheat oven to 350ºF. Prepare a large half sheet pan with parchment paper or spray with non-stick cooking spray.

2. To a small bowl or liquid measuring cup, combine very hot water with cocoa powder. This blooms the cocoa powder and enhances the chocolate flavor. Add very soft or melted butter and whisk together. Set aside and let cool while you mix up the other ingredients. This step can also be done with a saucepan on the stove, combining the three ingredients and boiling. It will take longer for the mixture to cool if you go this route.

3. To a large bowl, combine flour, sugar, baking soda and salt. Whisk together and set aside.

4. Grab another small bowl and whisk together the sourdough discard and eggs until completely incorporated. Add the sour cream (or yogurt) and vanilla and whisk again until smooth.

5. Pour the chocolate mixture on top of the flour mixture. Whisk until smooth. Then add the sourdough discard/egg mixture and whisk again until smooth and incorporated. Pour the cake batter into the sheet cake pan and smooth to the edges. Bake for 15-20 minutes until baked all the way through. Use a toothpick to check the middle of the cake - there should be no streaks of cake batter on the toothpick.

6. When the cake is done baking, prepare the chocolate glaze. Melt the butter until very warm and liquid. Add the cocoa powder and whisk together. Once again this helps bloom the cocoa powder and give a depth of chocolate flavor. Add the powdered sugar, milk (or coconut milk), vanilla and salt. Whisk together until smooth.

7. While still warm, pour the icing over the cake, spreading it evenly so it covers the cake completely. Let cool before serving and enjoy!

NOTE
Rich, chocolatey and delicious this sourdough version of my mom's Chocolate Sheet Cake is sure to impress at any event. It would be great served with homemade ice cream on a hot summer night!
