Preheat oven to 350 degrees. Line two baking sheets with parchment paper or silicon baking mats.
Combine the Sunbutter, egg, sugar, baking powder, vanilla, and lemon juice together in a mixing bowl and stir well. Roll about 1 tablespoon of dough into a ball for each cookie. Place on the prepared baking sheet and gently flatten the ball with a spatula. Press your thumb into the center of each cookie and fill with about ½ teaspoon of jelly. Repeat with remaining dough.
Bake for 15 minutes or until golden brown. Let cool on the pan.
