Ingredients
- 1 cup unsalted butter, room temperature
- 1 cup granulated sugar (plus extra for rolling)
- 1 large egg
- 1 tsp vanilla extract
- 2 ¾ cups all-purpose flour
- ½ tsp baking soda
- ½ tsp baking powder
- 1 pinch fine salt

Instructions
- Preheat oven to 350°F (175°C). Line baking sheets with parchment or silicone mats.
- Beat butter and sugar on medium-high speed for 2–3 minutes until fluffy.

- Gradually add dry ingredients to the wet mixture and mix just until combined.
- Divide dough into four bowls. Add a packet of Jello to each bowl and knead until evenly colored.
- Scoop 1-inch dough balls and roll in granulated or colored sugar.
- Arrange balls 2 inches apart on baking sheets, flatten slightly, and bake for 8–10 minutes until edges are just set.
- Cool on tray for 5 minutes, then transfer to a rack to finish cooling.
Notes
For best results, chill the dough before baking for plumper cookies and less spread. Use different Jello flavors for a full rainbow effect. Customize colors for seasonal themes—red and green for Christmas, or pastels for spring. Store in an airtight container up to 5 days or freeze dough balls for a month.
