These take a litte effort but my DD is a peanut butter lover and these are her favorite brownies. Got this from Southern Living.

These turned out really well. The one caution I would mention is the step wherein you microwave the peanut butter. Readers should be aware that many manufacturers today are sealing the jars with inner lids that are lined with a thin layer of metal. If you don't get every last bit of the metal liner off of the jar rim, you could be in for some fireworks inside your microwave - potentially, you could even start a fire and obliterate the oven. Transferring the peanut butter to a microwave-safe bowl is probably a lot safer. A bit more trouble, but a lot safer in the end.
