If your looking for something that the kids will love to help you make at the cottage, try what we refer to as our "PMS" cake. We made one last night and devoured it, all 7 of us.
First, bake a chocolat cake, I cheat and use the Betty Crocker Devil's Food cake, the kids mix it up and put it in the pan.
When the cake is ready, take it out of the oven, poke holes in it with a butter knife.
Pour on a can of Eagle Brand Condensed Milk.
Spread out a bag of chocolat chips on top of the cake. The heat of the cake will make them melt.
Spread out a bag of Skor's pieces, you can find them in the chocolat chip section in the stores. If you can't find any, buy 3 Skor's chocolat bars and break them into pieces.
Get 3 boxes of Smarties and break them into pieces, pour them over the cake.
Let the cake cool for about 10 minutes (the kids can't wait much longer than that).
Take a package of Cool Whip and spread it over top.
It's heavenly and almost like a hot molten lava cake.
