Get that glass of milk ready! These Classic Peanut Butter Cookies courtesy of our friends at Allrecipes are a perfect way to mark National Peanut Butter Day on Tuesday, January 24.

In a large bowl, beat 1 cup unsalted butter, 1 cup crunchy peanut butter, 1 cup white sugar and 1 cup packed brown sugar with an electric mixer until smooth. Beat in eggs one at a time.

In a medium bowl, sift 2 1/2 cups all-purpose flour, 1 1/2 teaspoons baking soda, 1 teaspoon baking powder and 1/2 teaspoon salt. Add to peanut butter mixture until just combined. Chill dough in refrigerator for 1 hour.

Preheat oven to 375 degrees Fahrenheit. Roll dough into 1-inch balls and place 2 inches apart on an ungreased baking sheet. Flatten each ball with a fork, making a crisscross pattern.

Bake until edges are golden, approximately 10 minutes. Cool on the baking sheet for 5 minutes, then place on a wire rack to cool completely.
