I had a hard time figuring out what sweet treat to make for you today. A couple of ideas were running through my mind but eventually decided to make this rich chocolate sheet cake packed and I mean packed with chocolate chips.

If you’re having a hard time figuring out how rich this chocolate cake is, let’s do a little math!

In the cake there are 4 oz of chocolate and 1/2 cups chocolate chips.

On top of the cake there are 8 oz of chocolate and almost 1 cup of chocolate chips.

Yes, this cake is a chocolate overload.

I’m a chocoholic and love when a recipe starts with melted chocolate. You can never go wrong with that.

What I also love, are recipes that can be made with very little dirty dishes.

You’ll need one bowl and one whisk/or a spatula to make the cake and another bowl to make the ganache on top.

Knowing that you don’t have to spend half a day washing dishes, I really think you should make this cake asap!

Pin it to your DESSERT BOARD to SAVE it for later!

In addition to the baking chocolate and chocolate chips, you’ll also need a few other ingredients I’m sure you already have on hand : butter, sugar, vanilla extract, eggs, flour and baking powder for the cake and heavy cream for the ganache.

Pantry samples (at least in my kitchen)

A quick note before I let you with the recipe.

I baked this chocolate cake in a 13X9″ sheet pan but if you don’t have one, use a regular 13X9″ pan and keep in mind the cake is not very tall. Don’t think you did something wrong and your cake didn’t rise as high as the baking pan.

  1. I am making this today for the chocolate lovers in the house. Sunday’s are my day to make a new dessert for the guys. They are wonderful guinea pigs! Wow, this was super thick, so cannot wait to see how it turns out. Thanks for the recipe!

  2. Is the sugar amount correct at 2 1/4 cups? I made this as stated and it was a total fail – by the time I added in the chocolate chips, the mixture was so thick I could barely stir it. I still tried to bake it, but needless to say, it didn’t turn out. (The top was a burnt shell, the inside still molten.) I’m sad, too, because it looks so delicious!

    1. I’m sorry this didn’t work out for you. As the recipe calls for dark chocolate, you need sugar to sweeten it or it turns out bitter. The cake batter hardens as the chocolate mixture cools down so it’s best to work quickly with this recipe. I hope that helps.

  3. I wish I had an excuse to make a sheet cake right now – this one! Because it looks delicious and love all the chocolate!
