If you're a fan of peanut butter cookies, you need this recipe. These gems are rich in peanut flavor and deliver the perfect balance of salty and sweet. They're also wonderfully soft and literally melt in your mouth.
Preheat the oven to 350 degrees. Line two large baking sheets with parchment paper.
In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
In the bowl of an electric mixer fitted with the paddle attachment, beat the butter until creamy. Add both sugars and beat until light and fluffy. Beat in the peanut butter until blended.
Beat in the egg and vanilla.
With the mixer on low speed, beat in the flour mixture.
Using your hands, roll the dough into 1-inch balls (use a small cookie scoop if you want to ensure each cookie is the same size). Transfer the balls to the prepared pans and flatten with a fork in a criss-cross pattern.
Bake for 9 to 10 minutes, until the edges of the cookies are just starting to turn color.
Cool cookies completely, on the baking sheet (on a wire rack) before serving.
Store the cookies in an airtight container for up to 1 week, or freeze up to 3 months.
