Preheat the oven to 350F and line two baking sheets with parchment.

Stir together the peanut butter, sugar, egg, and vanilla until a smooth dough forms.

Roll the dough into 24 balls, place on the sheets, and flatten slightly into a triangle shape with the point at the bottom.

Press two pretzel twists into the top corners for antlers.

Bake 8 to 10 minutes until set, then let cool 5 minutes on the pan.

While still warm, press on candy eyes and a red gumdrop nose so they stick.
