Reese’s Pieces-Peanut Butter Cookie

Adjust oven rack to low center position; heat oven to 350ºF. Sift flour, baking soda, baking powder, and salt in a medium bowl.

In the bowl of an electric mixer or by hand, beat butter until creamy. Add sugars; beat until fluffy, about 3 minutes with an electric mixer, stopping to scrape down the bowl as necessary. Beat in the peanut butter until fully incorporated, then eggs, one at a time, then vanilla. Gently stir dry ingredients into peanut butter mixture. Add candies and stir gently until just incorporated.

Working with 2 tablespoons of dough at a time, roll into large balls, placing them 2 inches apart on a parchment-covered cookie sheet. Gently flatten each dough ball with the bottom of a glass. Bake until cookies are puffed and slightly brown along the edges but not the top, 10 to 12 minutes (they will not look fully baked). Cool cookies on the cookie sheet until set, about 4 minutes, then transfer to a wire rack to cool completely. Cookies will keep, refrigerated in an airtight container, up to 7 days.
