Ingredients
- 1/2 cup unsalted butter, softened
- 3/4 cup packed brown sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1 1/4 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 teaspoon ground cinnamon (optional)
- 3/4 cup chopped fresh rhubarb (small dice)
Instructions

- Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
- Cream the butter and sugar: In a large bowl, beat butter and brown sugar until light and fluffy. Add egg and vanilla; mix until combined.
- Mix dry ingredients: In a separate bowl, whisk together flour, baking soda, salt, and cinnamon.
- Combine and fold in rhubarb: Add dry ingredients to the wet and mix until just combined. Gently fold in chopped rhubarb.
- Scoop and bake: Scoop dough onto the baking sheet using a tablespoon or cookie scoop. Leave space between cookies. Bake for 10–12 minutes, until edges are golden but centers are soft.
- Cool: Let cool on the baking sheet for a few minutes before transferring to a rack.
Tips & Variations
- For extra chewiness, chill the dough for 30 minutes before baking.
