Mix peanut butter, Truvia® Sweet Complete™, egg and vanilla extract together in a bowl until well combined.
Refrigerate dough for 30-45 minutes.
Preheat oven to 350°F (180°C).
Roll chilled dough into tablespoon-sized balls.
Add to a prepared baking sheet, flattening dough into small discs. Press down into each cookie with your thumb (or the end of a spatula/utensil) to create an indent in the center.
Spoon jam into the center of the cookies.
Bake 10-14 minutes, until browned on the sides.
Cool slightly before transferring to a rack and cooling completely.
Enjoy!
