These soft chocolate cookies have a big peanut flavor since they use peanut butter and peanut butter chips.
Preheat oven to 350°F.
Beat peanut butter, oil, brown sugar and granulated sugar in a large bowl with an electric mixer on medium speed until the sugars are blended. Beat in eggs, yogurt and vanilla until combined.
Whisk flour, cocoa, oats, baking soda and salt in a medium bowl. With the mixer on low speed, gradually add the dry ingredients to the peanut butter mixture until blended. (It will be sticky.) Stir in chocolate and peanut butter chips.
Using a small cookie scoop or slightly rounded tablespoons of dough, place cookies 2 inches apart on ungreased cookie sheets.
Dip the bottom of a glass in water and then in turbinado sugar. Use the sugared glass to flatten the cookies slightly, leaving a thin layer of sugar on top, rewetting the glass as needed.
Bake the cookies in batches until they are just set and the tops appear cracked, 8 to 10 minutes. (Do not overbake or they will be dry.) Cool on the baking sheet for 2 minutes before transferring to a wire rack to cool.
Ingredient Note: Turbinado sugar is steam-cleaned raw cane sugar. It’s coarse-grained and light brown in color, with a slight molasses flavor. Find it in the natural-foods section of large supermarkets or at natural-foods stores.
