These Peanut Butter and Jelly Cookies take this classic flavor combination to the next level. The texture of the gooey jelly with the crisp cookie is absolute perfection. These cookies will not last long, so you might want to double the recipe.
Stir sugars together. Blend in butter, peanut butter, vanilla and egg. Stir in flour to make a soft dough.
Roll dough into 1" diameter balls. Push thumb into the center of the cookie, careful not to flatten the cookie too much. The cookie should resemble a nest.
Bake until mostly done, about 7 minutes. Pull out the cookies and drop in about 1/2 t of preserves into the reservoir and bake 2-3 more minutes. Cool on a wire rack until the jelly is no longer hot.
