Made this tonight and my kids were in sugar heaven. This was a special treat so we went all out and any kid who likes Reese's will love this. Not hard to make at all. I ended up using peanut M&Ms on top because store was out of Reese's Pieces.

Wonderful, moist cake. Made this for my son and his fiance birthday. I used the Reese Mini's in the cake and to decorate the top and used crushed reeses on the sides. I also use Chocolate cool whip. Already had a request to make again next year. Thank you

My husband just loved this cake. It's very moist, but a bit too sweet for my taste. I don't matter though, since any baking I do, I do for my husband. LoL! I did have to make a modification in regards to the icing. I never buy Cool Whip, so I used the cream cheese and added 4 tblsp. of butter along with some milk and whipped it for a few minutes. Good idea for those leftover Reese's candies. :)
