  1. Instructions
  2. Preheat Oven: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.

  7. Fold in Rhubarb: Gently fold in the diced rhubarb until evenly distributed.
  8. Scoop Dough: Scoop tablespoon-sized dough balls and place them 2 inches apart on the baking sheets.
  9. Bake: Bake for 10–12 minutes or until edges are golden and centers are soft.
  10. Cool: Let cookies cool on baking sheet for 5 minutes, then transfer to wire rack to cool completely.
  11. Serve or Store: Serve warm or store in airtight container.

Notes

Notes
Use dark brown sugar if you want a deeper molasses flavor.
Frozen rhubarb works too—just thaw and pat it dry.
Chilling dough for 30 minutes yields thicker cookies.
Add a pinch of ginger or nutmeg for a spiced variation.
