1 teaspoon vanilla extract

1/4 teaspoon salt

1 cup rhubarb, chopped
Optional: powdered sugar for dusting

Step-by-Step Instructions

Preheat your oven to 350°F (175°C).
In a mixing bowl, cream together the brown sugar and butter until smooth.
Beat in the egg and vanilla extract until well combined.
In another bowl, whisk together the flour, baking soda, and salt.
Gradually add the dry mixture to the wet mixture, stirring until just combined.
Fold in the chopped rhubarb gently.
Drop spoonfuls of dough onto a baking sheet lined with parchment paper.
Bake for 10-12 minutes until the edges are lightly golden.
Let cool on the baking sheet for a few minutes, then transfer to a wire rack to cool completely.
Dust with powdered sugar if desired before serving.

Tips for Success — Brown Sugar Rhubarb Cookies

Chop rhubarb small (about 1/4-inch) so it distributes evenly and doesn’t make the dough too wet.
Pat rhubarb dry on paper towels if very juicy to avoid soggy dough.
Use cold baking sheets between batches to keep cookie shape consistent.
Measure flour by spooning into the cup and leveling — too much flour makes cookies dense.
If dough is sticky, chill 10–15 minutes for easier scooping.

Variation (if any)

Add 1/2 cup chopped white chocolate or a handful of chopped walnuts for extra texture.
Swap half the brown sugar for granulated sugar for a less-dense crumb.
For a layered dessert twist, crumble cooled cookies into a trifle — try a similar idea in a classic brownie trifle and adapt with rhubarb and whipped cream.

FAQs

Q: Can I use frozen rhubarb?
A: Yes — thaw and drain frozen rhubarb well, then pat dry before folding into dough to avoid excess moisture.

Q: How should I store these cookies?
A: Store in an airtight container at room temperature for up to 3 days. Refrigerate for longer storage up to a week, or freeze baked cookies for up to 3 months.

Q: Can I make the dough ahead?
A: Absolutely. Chill the dough for up to 48 hours or freeze scooped dough balls on a tray, then transfer to a bag. Bake from frozen, adding 1–2 minutes to the bake time.

Q: My cookies spread too much — what went wrong?
A: Ensure your butter wasn’t too soft or melted, and check your flour measurement. Chilling the dough briefly helps control spread.

Q: Can I replace the butter with oil or margarine?
A: Butter gives the best flavor and structure. Substituting oil will change texture and may cause more spread; margarine can work but may affect flavor.
