Chocolate Sheet Cake Recipe

Pin It

Calling all chocoholics!

This chocolate cake is a true sweet fix with both batter and frosting chocolate!

This was my first time making this particular sheet cake recipe. At first I thought the recipe looked a bit involved but it really wasn’t. It was fairly simple. Just mix your dry ingredients as the recipe reads then make the stove top part. Add it all together. Really quite simple.

Now when it came to the frosting; that was truly involved and not my strongest baking quality. Putting the ingredients together was easy but the stirring on the stove top was challenging. It made you feel stir crazy. At least it did me! When you pour it top of the cooled cake you need to quickly spread it around. It sets very quick. At least it did for me.

The taste is super sweet! All the stirring with the frosting was worth it. So if you’re a chocolate lover this cake is for YOU!
