Preheat your oven to 350° and line a cookie sheet with parchment or a silicone baking mat.

Combine the egg, brown sugar, peanut butter, vanilla baking soda and salt, and stir.

Use a tablespoon to measure out the dough, and place on the prepared pan.

Make a small divot in the center of the cookie with the back of your measuring spoon, be careful not to go too deep. Scoop out 1/2 teaspoons of jam and place into the center of each divot.

Bake for 10-12 minutes and then let cool for 10 minutes on the pan before, very carefully, removing then to a wire rack.

Serve with an ice cold glass of milk and enjoy!
