1. In a bowl, whisk flour, baking powder, baking soda and salt. In a large bowl, using an electric mixer on medium speed, beat butter, peanut butter and sugars until light, about 3 minutes. Beat in eggs, then flour mixture. Cover and chill for at least 2 hours.
2. Preheat oven to 350ºF. Line 2 large baking sheets with parchment. Roll 1 heaping Tbsp. of dough into a ball. Place on a baking sheet. Use a fork to flatten in a crisscross pattern. Repeat with remaining dough until both sheets are filled. Make an indentation with your thumb in center of each cookie. Keep remaining dough chilled between batches.
