Peanut-Butter Chocolate-Chunk Cookies
Heat the oven to 350 degrees. In the bowl of an electric mixer fitted with the paddle attachment, cream the butter, peanut butter, and sugars together until light and fluffy. Add the egg and vanilla and mix on medium speed until combined. Sift flour and baking soda together, and add to butter mixture, beating just to combine. Fold in chocolate chunks.
