Preheat the oven to 350°F.

In a large mixing bowl, cream together ½ cup peanut butter, ½ cup butter, ½ cup granulated sugar, and ½ cup brown sugar until smooth.

Add 1 egg and 1 teaspoon vanilla extract and beat until fully combined.

In a separate bowl, whisk together 1? cups flour, 1 teaspoon baking soda, and ½ teaspoon salt.

Slowly add the dry ingredients to the peanut butter mixture, mixing until fully incorporated.

Roll the dough into 24 approximately 1-inch balls and place them several inches apart on a baking sheet.

Gently press a small indentation into the center of each cookie.

Bake for 12–14 minutes.

Immediately place 1 unwrapped Hershey Kiss into the center of each warm cookie.

Allow cookies to cool slightly before serving. Enjoy!
