- 1/2 cup (1 stick) salted butter, softened to room temperature
- 1/2 cup dark brown sugar
- 1/4 cup granulated sugar
- 1 large egg
- 3/4 cup creamy peanut butter
- 1 teaspoon vanilla extract
- 1/2 teaspoon baking soda
- 1 and 1/4 cups all purpose flour
In a large bowl with a handheld or stand mixer, cream butter and sugars together until light and fluffy. Mix in peanut butter, then the egg, and then the vanilla. Slowly mix in the dry ingredients. Do not overmix. Chill dough for at least 30 minutes.
Preheat oven to 350 degrees. Remove chilled dough from fridge and roll into balls. Spread a thin layer of granulated sugar on a plate and roll each dough ball to evenly coat (if desired).
On an ungreased baking sheet, bake for 8-9 minutes, until the tops begin to *slightly* crack. Do not bake longer than this. Cookies will look undone, but will firm up as they cool
