These gluten-free peanut butter cookies are so easy to make! All you need is one bowl and a few simple ingredients. The recipe uses gluten-free flour, which gives them crisp edges and a tender center.
Mix the peanut butter, butter, granulated sugar, brown sugar, and egg in a large bowl until smooth and fluffy, about 30 seconds.
Stop the mixer. Add the gluten-free flour, baking soda, baking powder, and salt. Mix until a dough forms.
Cover bowl and chill dough for 30 minutes.
Preheat oven to 375° F. Line two baking sheets with parchment paper.
Scoop the dough, about one heaping tablespoon, into balls. Roll in the ½ cup additional granulated sugar. Place dough, about 2 inches apart, onto prepared baking sheets. Dip a fork into the sugar and press a crisscross pattern into the top of each cookie.
Bake until edges are light golden brown. For chewy cookies, bake about eight minutes. For crisp cookies, bake about 10 minutes. Rotate pans halfway through baking.
Remove the pans from the oven. Allow cookies to cool on the pan for three to five minutes. Transfer cookies to a cooling rack. Repeat with remaining dough.
Store cookies in an airtight container for up to four days or freeze cooled cookies in an airtight container for up to three months.
Gluten-Free Flour: Use an all-purpose gluten-free flour that contains xanthan or guar gum. These cookies were tested with Bob's Red Mill 1:1 Gluten-Free Baking Flour.
