Preheat oven to 350 degrees. Whisk together flour, baking powder, baking soda, and salt. Beat peanut butter and butter with a mixer on medium speed until smooth. Add sugars, and beat until pale and fluffy. Add egg and vanilla, and beat until incorporated. Reduce speed to low. Add dry ingredients, and mix until combined.

Scoop level tablespoons of dough, and form into balls. Roll each ball in granulated sugar, and transfer to parchment-lined baking sheets, spacing about 2 inches apart.

Heat jam in a small saucepan, stirring, until loosened, about 30 seconds. Spoon about 1/2 teaspoon into each indentation. Cookies can be stored in a single layer for up to 1 week.

Notes- I did my Thumbprint before they went into the oven oops 😬all I did was reshape them with a spoon. Because I didn’t have any room on my plate I was cooking them on I put them back on the cookie sheet, that was cooled completely to finish them up..
