1 cup peanut butter
1/2 cup granulated sugar
1/2 cup brown sugar
1 teaspoon baking powder
1/2 teaspoon vanilla extract
(plus granulated sugar for rolling dough)
Mix first 6 ingredients with a mixer, on medium/high. The dough should be sorta fluffy. Roll into tablespoon sized balls (yes, it will be sticky, just try your best :) Roll each ball in sugar. Bake at 350 for about 12 minutes, until bottoms are lightly brown.
So I've made these before, but I couldn't remember what the recipe was exactly..I looked it up online, and found a bunch of recipes calling for baking soda, and bunch calling for baking powder, and a bunch more not asking for any leavening at all...hmm
So Emily and I did an experiment. One batch with baking powder, one without. On the pan, the cookies on the right have baking powder; in the other picture, the cookie on the bottom had baking powder. Definitely go WITH baking powder, the cookies looked better, were softer, and just overall better.
