Expert Tips / Pro Tips
For the best results, ensure your rhubarb is finely chopped. This will distribute the tartness evenly throughout the cookie and prevent large, fibrous pieces. If your rhubarb stalks are particularly thick or stringy, you can blanch them briefly in boiling water for about 30 seconds, then shock them in ice water before chopping. This will soften them slightly. Chilling the dough for at least 30 minutes before baking can help prevent the cookies from spreading too much, resulting in thicker, chewier cookies.
Variations & Substitutions
You can easily adapt these Brown Sugar Rhubarb Cookies to suit your tastes. For an extra burst of flavor, add the zest of one lemon or orange to the dough. If you don’t have nuts, you can omit them entirely or substitute with oats for a different texture. For a touch of warmth, a pinch of cinnamon or nutmeg can be added with the dry ingredients. If you can’t find fresh rhubarb, frozen rhubarb can be used; ensure it’s thoroughly thawed and patted dry before chopping.
Serving Suggestions
These Brown Sugar Rhubarb Cookies are delicious on their own, but they also pair wonderfully with a glass of cold milk, a cup of tea, or even a scoop of vanilla ice cream for a delightful dessert. They make a charming addition to brunch spreads, picnics, or afternoon tea.
Storage, Freezing & Reheating
Store cooled cookies in an airtight container at room temperature for up to 3-4 days. For longer storage, they can be frozen. Place completely cooled cookies in a single layer on a baking sheet and freeze until solid, then transfer them to a freezer-safe bag or container. They will keep in the freezer for up to 3 months. Thaw at room temperature. To reheat slightly, place a cookie in a warm oven (around 300°F/150°C) for a few minutes until warmed through.

FAQ
Can I use frozen rhubarb?
Yes, you can use frozen rhubarb. Thaw it completely and then pat it very dry with paper towels to remove as much excess moisture as possible before chopping and adding to the dough. This helps prevent the cookies from becoming too moist.
Several factors can cause cookies to spread excessively. Ensure your butter isn’t too soft or melted. Baking soda that is old or expired can also contribute to spread. Baking the cookies when the dough is chilled can help firm them up and reduce spread.
How do I chop the rhubarb?
Wash the rhubarb stalks and trim off the ends. Chop them into small pieces, about ¼-inch to ½-inch in size. If your rhubarb is stringy, you can peel it lightly with a vegetable peeler before chopping.
You can attempt a gluten-free version by substituting a good quality all-purpose gluten-free flour blend for the all-purpose flour. You may need to adjust the liquid content slightly, as gluten-free flours can absorb moisture differently.
