Alright guys, this Nutella Brownie Cake may be my most decadent brownie cake to date.

It’s what chocolate lover dreams are made of.

How to Make Chocolate Ganache:

Chocolate ganache is a simple blend of heavy cream and chocolate. It makes a heavenly topping for cakes, cupcakes, and brownies. You can make different textures of ganache by adjusting how much heavy cream you use. For this recipe I used a 2:1 chocolate to heavy cream ratio to make a chocolate ganache that could be poured and then spread to cover the top of the cake. To make the chocolate ganache you:

  1. Chop up 2 cups of chocolate and place it in a bowl.
  2. In the microwave heat 1 cup of heavy cream until it is boiling (about 1 minute depending on your microwave).
  3. Pour the heavy cream over the chocoalte and let it sit for 30 seconds. Then stir the chocolate and cream together until the chocolate is fully melted and smooth.

Note: If your chocolate doesn’t melt complete and the mixture has cooled down you can microwave for 15 seconds at a time until the ganache is smooth.

What to Decorate Your Nutella Brownie Cake With:
