This makes a fairly large cake so if you have a small family, you might want to cut the recipe in half. You’ll end up with a shorter cake, but it still tastes just as good.
The recipe calls for a springform pan, which is what I use, but if you don’t have one, you could just use a 9×13 pan and cut the cake into squares instead of wedges.Chocolate-Peanut Butter Ice Cream Cake
6 cups Rice Krispies12 oz. package chocolate chips2/3 cup peanut butter1 gallon of ice cream, whatever flavor you like, so long as it goes with peanut butter and chocolate
1) Combine peanut butter and chocolate chips in a saucepan and stir over low heat until the chocolate chips are melted.
2) Pour the chocolate mixture over the Rice Krispies and stir gently until the cereal is thoroughly coated. Pour the cereal out onto a jelly roll pan (or a cookie sheet), and let it cool.
3) Soften the ice cream, and once you’ve broken all of your chocolate cereal mixture up into smallish chunks, fold all but one cup into the softened ice cream. Pour/press the mixture into a 9-inch springform pan. Mine is 8 inches, but it works fine.
4) Sprinkle/press the remaining chocolate cereal on top of the ice cream cake, cover with plastic wrap, and freeze until firm.
5) When you’re ready to serve your cake, loosen the sides of the springform pan and slice the cake into wedges. If the cake is really hard and difficult to slice, you can let it sit for a few minutes so that it will soften.
