¼ teaspoon salt

Baking Tools and Equipment Needed

You won’t need any fancy tools, just a few kitchen basics:

Mixing bowls (medium and large)
Hand or stand mixer
Measuring cups and spoons
Rubber spatula
Baking sheet
Parchment paper or silicone baking mat
Cookie scoop (optional but helpful)
Cooling rack

How to Make Brown Sugar Rhubarb Cookies Step-by-Step

Preheat and Prep
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat for easy cleanup.
Cream Butter and Sugar
In a large mixing bowl, cream together the softened butter and brown sugar using a hand mixer or stand mixer until smooth and fluffy, about 2–3 minutes.
Add Egg and Vanilla
Beat in the egg and vanilla extract until fully incorporated and creamy.
Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry mixture into the wet ingredients, mixing until just combined.
Fold in Rhubarb
Gently fold in the chopped rhubarb using a spatula. Make sure it’s evenly distributed throughout the dough.
Scoop and Bake
Drop spoonfuls of dough (about 1 tablespoon each) onto the prepared baking sheet, spacing them 2 inches apart. Bake for 10–12 minutes, or until the edges are lightly golden but centers are still soft.
Cool and Serve
Let the cookies rest on the baking sheet for 5 minutes, then transfer to a cooling rack. Enjoy warm or let them cool completely for optimal texture.

Baking Tips for the Best Rhubarb Cookies

Chop rhubarb small: This ensures even baking and no large, soggy pockets.
Don’t overmix: Mix just until combined to avoid dense cookies.
Watch the bake time: Cookies will continue to set as they cool. Remove when edges are set but centers are still slightly soft.
Soften butter properly: It should dent when pressed but not be shiny or melting.

Common Mistakes to Avoid When Making Rhubarb Cookies

Using too much rhubarb: Stick to 1 cup; too much can make cookies wet and cakey.
Skipping parchment paper: Helps with even baking and easy cleanup.
Baking too long: Leads to hard, dry cookies. Remove from the oven when just golden.
Not drying rhubarb: If rinsed before chopping, pat dry with paper towels to reduce excess moisture.

Variations and Add-Ins for Rhubarb Cookies

Spiced Rhubarb Cookies: Add ½ teaspoon cinnamon or nutmeg for a warm, cozy flavor.
Nutty Delight: Try adding chopped walnuts or pecans for crunch.

Storage and Freezing Tips for Rhubarb Cookies

Room Temperature:
Store in an airtight container at room temperature for up to 4 days.

Refrigeration:
Not necessary unless it’s very humid; if refrigerated, bring to room temp before serving.

Freezing:
Place cooled cookies in a freezer-safe container with parchment between layers. Freeze for up to 2 months. Thaw at room temp when ready to enjoy.

Freeze the Dough:
You can also scoop the dough onto a baking sheet, freeze until solid, and then store in a zip-top bag. Bake from frozen—just add 1–2 minutes to baking time.

Can I Use Frozen Rhubarb in These Cookies?

Yes, but with caution:

Thaw completely and drain excess liquid before adding to dough.
Pat dry thoroughly with paper towels—excess moisture can make cookies soggy.
Use the same measurement (1 cup), but chop large frozen pieces into smaller bits.

Fresh rhubarb is ideal for texture, but frozen rhubarb makes this recipe accessible year-round.

FAQs About Brown Sugar Rhubarb Cookies

Can I use white sugar instead of brown?
Brown sugar is essential for flavor and moisture. Using white sugar will change the texture and taste.

Do I need to peel rhubarb before using it?
Nope! Just trim the ends and chop. Peeling is only necessary if the stalks are very tough or stringy.

Why are my cookies spreading too much?
Ensure your butter isn’t too warm and measure flour correctly. Chilling the dough can help, too.

Are these cookies very tart?
No, the rhubarb’s tang is mellowed by the brown sugar, creating a balanced sweet-tart flavor.
