Peanut Butter Christmas Cookies

Preheat the oven to 350 degrees F (175 degrees C). Line 3 to 4 baking sheets with parchment paper.

Cream butter, white sugar, and brown sugar together in a bowl using an electric mixer. Beat in peanut butter and egg. Stir in sour cream and vanilla extract.

Stir flour, baking powder, and baking soda together in a separate bowl. Add to the peanut butter mixture; stir to blend well.

Scoop a teaspoonful of dough and shape into mini balls. Place about 2 inches apart on the prepared baking sheets. Indent the center of each cookie using a chopstick.

Bake in the preheated oven until lightly browned, about 15 minutes. Let cool completely, 20 to 30 minutes. Fill each with strawberry jam.
