This cake is so easy and so delicious I made it twice in one week! The cake is super moist and really does taste like a smore. I made mine in a bunt pan; it was beautiful when it was done. I garnished the finished cake with gram cracker quarters, bits of chocolate bar and mini marshmallow. The finished cake looks like you were in the kitchen for hours. I had better luck with the fudge in the cake by putting half of my cake batter in, then the fudge, then finishing it off with the remaining batter. This cake is a great summer time hit!! I am going to try it in the Dutch Oven this weekend!

Looks gooey and delicious,I'm having a hard time keeping little fingers out of the cake! I tried the bundt pan and the bottom stuck for me, I'm not sure why, but the marshmallow creme made it all workable anyhow. I think I'll stick to plopping the fudge in from the top instead of trying to put it in between layers of batter next time around. Great recipe, thanks for sharing!

This cake was a huge hit at Game Night. Instead of the hot fudge and marshmallow creme on top, I used the marshmallow cream, graham cracker crumbs, and 2 chopped Hershey bars.
