Method
Prep and preheat
- Preheat the oven to 350°F and line baking sheets with parchment paper.
- Whisk together all-purpose flour, baking soda, and salt until evenly combined.
Mix the dough
- Cream the butter and brown sugar until fluffy.
- Beat in the eggs and vanilla extract until smooth and combined.
- Gradually mix in the flour mixture until just combined, with no dry streaks left.
- Fold in the diced fresh rhubarb and the chopped walnuts if using.
Shape and bake
- Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart.
- Bake at 350°F for 10-12 minutes, until the edges are lightly golden and the centers are set.
Cool
- Cool on the baking sheet for 5 minutes before transferring to a wire rack.
Notes
Pro tip: Dice the rhubarb finely so it disperses through the dough instead of pooling, helping keep the cookies soft. Store airtight at room temperature for up to 3 days or refrigerate up to 5 days; freeze baked cookies up to 2 months. For a lower-sugar swap, reduce brown sugar by about 1/4 cup and use an equal amount of a brown sugar substitute that measures cup-for-cup.
