Key to Success #1 – Use a Sturdy Sheet Cake Pan
When you make a sheet cake, you’ll need a nice quality Sheet Cake Pan.
I use a half-sheet pan that is 13 X 18 X 1-inch high.
This Chocolate Sheet Cake recipe fits perfectly in a pan this size.
Your cake will bake up perfectly with just enough space for the decadent frosting on top.
Key to Success #2 – No Mixer Required
This Chocolate Sheet Cake recipe is so easy that you can make the chocolate cake batter in one pot.
No need to mess up a bunch of dishes. Just use your favorite wooden spoon.
I use a medium-sized stainless steel saucepan like this one.
I always use stainless steel pots because they stay in good shape and last forever.
You can use any kind of utensils with them and there’s no nonstick coating to flake off into your food.
Key to Success #3 – Don’t Wait to Make the Frosting
While your cake is baking in the oven, it’s time to start working on your rich chocolate frosting.
You’ll want to pour the frosting over the warm cake as soon as it comes out of the oven.
Frosting the cake when it’s warm will let that delicious frosting melt into the top of your cake so that it all melts together into one mega-fantastic Chocolate Sheet Cake.
