Peanut Butter Pinwheel Cookies with Melted Chocolate Swirl
This Peanut Butter Pinwheel Cookie recipe combines peanut butter dough with a layer of melted chocolate. Roll the dough into a jellyroll shape before slicing.
Mix the dough: Cream 1/2 cup butter and 1 cup granulated sugar until light and fluffy. Blend in 1/2 cup chunky peanut butter, 2 tablespoons milk, 1/2 teaspoon vanilla extract, and 1 large egg.Stir in the 1-3/4 cup unbleached all-purpose flour, 1/2 teaspoon table or sea salt, and 1/2 teaspoon baking soda.
Melt the chocolate: Microwave 1 6-ounce package semi-sweet chocolate chips for 1 minute. Stir until smooth, then let it cool slightly.
Roll out the dough: Press dough into a ball and place between two long sheets of waxed paper. Roll out into a 10 x 17-inch rectangle.
Add chocolate and roll up: Remove top sheet of waxed paper. Spread melted chocolate evenly over dough. Starting from a long edge, roll into a tight log.
Chill and slice: Wrap log and chill for 30–45 minutes until firm but not hard. Slice into ½-inch rounds using a serrated knife.
Bake the cookies: Preheat oven to 375°F (190°C). Place cookies on a parchment-lined baking sheet. Bake for 12–14 minutes. Transfer to a rack to cool.
