This produced a great ice cream! I did two things differently: I mixed the ingredients up in a bowl using a hand mixer and everything combined nicely. I did chill the mix overnight, then put it in the ice cream freezer. The freezer recommended 20 to 30 minutes in the freezer, and I found it needed to run closer to the 30 minutes' time. The only thing I recommend against is combining the ingredients in the freezer bowl because when it's frozen, the ingredients will start to freeze before they are fully combined. I agree with a previous reviewer: this ice cream is outstanding even without the PB cups added in.

I made these last weekend, as part of a dessert donation to a local shelter. I used chocolate graham crackers for the base as I had that on hand, but otherwise adhered to the recipe. Then I piped buttercream onto each of the brownies. I was very pleased with the recipe--in particular, I found the chocolate taste to be pleasantly intense but not overly sweet. The ratio of cocoa powder to sugar was perfect. Brownies were nice and crunchy on the bottom and chewy on the inside. I will be making these again.
