Method
Prep the oven and sheets
- Preheat oven to 350°F and line baking sheets with parchment paper.
Mix dry ingredients
- Whisk together all-purpose flour, baking soda, and salt until evenly combined.
Cream wet ingredients
- Cream butter and brown sugar until fluffy, then beat in eggs and vanilla extract.
Combine and fold in rhubarb
- Mix in dry ingredients until just combined, then fold in finely diced fresh rhubarb.
Shape and sprinkle
- Drop rounded tablespoons of dough onto prepared sheets, spacing about 2 inches apart.
Bake
- Sprinkle the tops with sugar, then bake at 350°F for 10-12 minutes until edges are set but centers still look soft with a slightly underdone center.
Cool and transfer
- Cool on the baking sheet for 5 minutes before transferring to a wire rack to finish setting.
Notes
For clean rhubarb pieces in every bite, dice the rhubarb finely and blot it lightly if it looks very wet. Store cookies in an airtight container for up to 3 days at room temperature; freeze up to 2 months. For a dairy-free swap, use a 1:1 butter substitute stick (softened) to keep the cookie texture tender.
