Do you love peanut butter? I mean, do you love peanut butter? Because I love peanut butter. It's one of my favorite foods ever, and I will eat almost anything that contains it (whether it's a dessert or not). So for me and these cookies, being gluten-free simply eliminated one more barrier between me and one of my favorite foods. That pesky flour is gone, and what is left is just the delicious intensity of the peanut butter. You will not be able to eat just one of these!
Cream the peanut butter and sugar in a bowl. Add the baking powder, and mix well. Then beat in the egg.
