I made this cake twice in the past week because I had so many of the ingredients left over. I found the recipe while searching the net for a cake that was both chocolate and caramel. The recipe can be found here.
Just a few notes, you will want to be careful making the caramel sauce, you can burn it easily. However, I didn't drizzle it on either cake and the second time I made the cake I just used 3 Tbsp of dulche de leche (with a little salt) in the butter cream instead of 1 Tbsp and 2Tbsp of the caramel sauce. I also found that the whipped ganache makes enough for two cakes, cut it in half.
It is easier to figure out what you need when it is all combined as I have down below (I have factored in half the whipped ganache suggestion):
-1 devils food cake mix
-2 3/4 c heavy cream
- 1 1/2 c sugar
- 1 lb chocolate chips
- 3 sticks butter
- 1Tbsp Dulche de Leche
- 1 c powdered sugar
- salt
- vanilla
