homemade triple chocolate sheet cake

This chocolate sheet cake recipe has a few steps, but it is super delicious and your family and friends will love it.  Having 3 different kinds of chocolate, kinda makes it worth it too.

We start making the frosting half way through the cooking process, so it’s ready when it comes out of the oven.

2 cups sugar
1/4 teaspoon salt
