This cake was good and easy, containing things I generally have on hand. I wish I had done 3 things though: 1) I was afraid it was too much butter and water. I halfed those and should not have because those are probably what makes the sauce thin enough to fill the holes well. 2) I should have made more holes. 3) I should have made the holes BIGGER! I did use only a 12 oz pkg. of milk chocolate chips, and do not regret that. It was yummy and went well with ice cream. Read More

Had difficulty getting the chocolate to go down in the holes. It was more like just a white cake with very thick frosting. The flavor of the the chcolate was good but the whole thing was way too rich. Even my kids would not eat it. Read More

I seem like a broken record when I rate recipes, but once again, yum! So easy to make. You have to use a wooden spoon so you get large holes for the fudgey part to get down in the cake. I wouldn't change a thing about this cake. The biggest problem I have is making this cake last more than one day in my house. Thanks Deb! Read More

Very tasty - Holes poked in cake must be large enough for frosting to flow into otherwise you end up with about 1/4" of a thick chocolate frosting on top of a white cake. Read More

I made this recipe as written except I added a little vanilla extract to the cake mix. I always do this I think it makes the box mixes taste better. And I have to give this a "5 star" rating. It may not be the fanciest cake ever. But it taste really good. It's very easy to make and you probably already have the ingredients on hand. Do make the holes plenty big and make sure the cake is right out of the oven when you put the chocolate mixture on. I just kept going over the cake with the spatula and the filling was pushed into the holes. I baked the cake in a glass pan so I could check it at the bottom. The semi-sweet chocolate is very rich. If you're not a chocolate lover you may prefer to use milk chocolate chips. Please try. Read More

My youngest son wanted a "Reese's Peanut Butter Cup Cake" for his birthday and this was the PERFECT recipe for that. My only modification was to use a chocolate cake mix and cut up Peanut Butter cups on top. It was a HUGE hit! Read More

This is a great recipe. I used the Chocolate Cavity Maker Cake recipe from this site instead of the cake suggested in this recipe. Boy was it rich! I took it to my office and everyone loved it. It would even be good without the peanut butter. You could also try putting cinnamon in with the chocolate instead of peanut butter. Read More

The recipe was delicious as is but the second time I made it was even better. I used yellow cake mix and a bag of mixed chips- peanut butter and chocolate chip. I also sprinkled crushed peanut butter cups on top after it had cooled. Read More
