Ingredients for Brown Sugar Rhubarb Cookies

All-Purpose Flour: The base of your cookie dough. Provides structure without being too dense.
Baking Soda: Helps the cookies rise just enough to stay chewy.
Salt: Enhances the sweetness and balances the tart rhubarb.
Unsalted Butter: Softened to create a smooth, rich base for creaming with sugar.
Packed Light Brown Sugar: Adds moisture and a deep, caramelized sweetness.
Large Egg: Acts as a binder and adds richness.
Vanilla Extract: A warm, comforting background flavor.
Fresh Rhubarb: Finely diced and patted dry to reduce moisture. Its tartness makes these cookies truly shine.

How to Make Brown Sugar Rhubarb Cookies

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking and ensure even baking.

Step 2: Mix Dry Ingredients

In a medium mixing bowl, whisk together the flour, baking soda, and salt. Set aside. This helps ensure even distribution of the leavening agent.

Step 3: Cream the Butter and Sugar

In a large bowl, use an electric mixer to cream the softened butter and brown sugar together until light, fluffy, and fully incorporated. This usually takes about 2-3 minutes.

Step 4: Add Egg and Vanilla

Beat in the egg and vanilla extract until the mixture is smooth and creamy.

Step 5: Combine Wet and Dry

Gradually add the flour mixture to the butter mixture, mixing just until everything is combined. Be careful not to overmix or your cookies could turn out tough.

Step 6: Fold in the Rhubarb

Gently fold in the finely diced rhubarb. Make sure you’ve patted the rhubarb dry with paper towels so it doesn’t make the dough too wet.

Step 7: Scoop and Bake

Using a cookie scoop or tablespoon, portion the dough onto your prepared baking sheet, spacing the cookies about 2 inches apart.

Bake for 10–12 minutes, or until the edges are lightly golden and the centers are just set.

Step 8: Cool and Enjoy

Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. Serve with a hot cup of tea, coffee, or even a cold glass of milk.

Tips for Success

Pat Dry Your Rhubarb: This step helps avoid soggy cookies.
Don’t Overbake: The cookies will continue to firm up as they cool.

Let Butter Soften Naturally: Avoid melting it in the microwave—you want it soft, not runny.

Serving Suggestions

These cookies pair beautifully with herbal teas like chamomile or mint.
Add a dollop of whipped cream or a smear of mascarpone for a dessert-like treat.

Variations To Try
