Preheat your oven to 350 degrees F and prepare a cookie sheet with a baking mat or parchment paper.

Beat butter with a paddle attachment until creamy. Add is sugar, egg, and vanilla and beat until combined. Gradually add in flour and baking powder until blended.

Divide dough into 6 sections. Sprinkle 2 tablespoons of Jell-o onto each section. Knead together with dough.

Shape dough into 1-inch balls and roll in the extra jello from the packets. Place on a baking sheet lined with a silicon mat and flatten with the bottom of a cup.

Bake 8 to 10 minutes. Cool for 2 minutes on the baking sheets, then transfer to wire rack and cool completely.
