When rhubarb season begins, I always look for new ways to use those bright pink stalks. While I enjoy crisps and muffins, I often crave something soft and chewy. That is exactly why I bake these Brown Sugar Rhubarb Cookies. They feel cozy and comforting, yet they still deliver that fresh, tart bite. Moreover, they come together quickly, so you can enjoy homemade cookies without spending hours in the kitchen.

Why You’ll Love These Brown Sugar Rhubarb Cookies
Perfect Sweet and Tart Flavor Balance
Brown Sugar Rhubarb Cookies combine deep caramel sweetness with a bright, tangy twist. The brown sugar adds richness, while the rhubarb balances everything with gentle tartness. As a result, each bite tastes full and layered. In fact, the contrast keeps the cookies from ever feeling too sweet.
Soft and Chewy Texture with Crisp Edges
Because brown sugar holds more moisture than white sugar, these cookies stay soft in the center. Meanwhile, the edges turn lightly golden and slightly crisp. So you get the perfect texture combination in every bite. The middle stays tender, and the outside offers a delicate crunch.
Quick 10 Minute Prep and Simple Pantry Ingredients
You only need about 10 minutes to prepare Brown Sugar Rhubarb Cookies. First, gather your pantry staples. Then mix everything in one bowl with simple steps. Since the ingredients are basic and familiar, this recipe feels easy and approachable.
A Delicious Way to Use Fresh Rhubarb
If you have extra rhubarb on hand, these cookies provide a fun alternative to traditional desserts. Instead of baking another crumble, you can fold diced rhubarb into cookie dough. However, if you still love classic fruit desserts, you can always bake a crisp alongside these cookies for a complete treat.
Ingredients You’ll Need
Wet Ingredients
To make Brown Sugar Rhubarb Cookies, you need:
- 1 cup light brown sugar
- 1/2 cup butter, softened
- 1 teaspoon vanilla extract
- 1 large egg
First, allow the butter to soften. Then cream it with the brown sugar until smooth and fluffy.
Dry Ingredients
You will also need:
- 1 3/4 cups all purpose flour
- 1 teaspoon ground cinnamon
- 1/2 teaspoon salt
- 1/2 teaspoon baking soda
- 1/2 teaspoon baking powder
Together, these ingredients provide structure and lift. Meanwhile, cinnamon adds a warm background flavor.
Preparing and Dicing the Rhubarb
Use 1 cup finely diced rhubarb. Slice the stalks into small pieces so they distribute evenly. If the rhubarb appears very moist, pat it dry before mixing it in. That simple step helps control excess moisture in the dough.
How to Make Brown Sugar Rhubarb Cookies Step by Step
Step 1: Preheat the Oven to 375°F
First, preheat your oven to 375°F. Line a baking sheet with parchment paper to prevent sticking.
Step 2: Cream Butter, Brown Sugar, Vanilla, and Egg
Next, beat the softened butter and brown sugar until light and fluffy. Then add the vanilla and egg. Mix until the batter looks smooth and creamy.
Step 3: Combine the Dry Ingredients
Add the flour, cinnamon, salt, baking soda, and baking powder. Stir gently until a soft dough forms. However, avoid overmixing, because that can make the cookies dense.
Step 4: Fold in the Fresh Rhubarb
Gently fold the diced rhubarb into the dough. Stir just enough to distribute it evenly. As a result, every cookie will contain little bursts of tart fruit.
Step 5: Scoop into 1 Inch Dough Balls
Scoop the dough into 1 inch balls and place them slightly apart on the baking sheet. They will spread slightly while baking.

Step 6: Bake for 12 to 14 Minutes
Bake for 12 to 14 minutes, or until the edges turn lightly golden. The centers should look set but still soft.

Step 7: Cool on Pan, Then Transfer to Wire Rack
Let the cookies rest on the baking sheet for a few minutes. Then transfer them to a wire rack to cool completely. Meanwhile, the centers will continue to firm up.
Baking Tips for Soft, Chewy Cookies
Adjusting for Excess Rhubarb Moisture
If the rhubarb releases extra juice, add a small amount of flour and extend the baking time slightly. This adjustment helps the cookies maintain their shape.
How to Prevent Overmixing
Mix only until the ingredients combine. Overmixing can develop too much gluten and affect the texture. So once the dough forms, stop stirring.
Knowing When the Cookies Are Done
Look for golden edges and soft centers. They may appear slightly underbaked, but they will firm up as they cool.
Storage and Freezing Instructions
Storing at Room Temperature for Up to 3 Days
Store Brown Sugar Rhubarb Cookies in an airtight container at room temperature for up to 3 days. Because they contain brown sugar, they stay moist and tender.
Freezing for Up to 1 Month
You can freeze fully cooled cookies in a sealed container or freezer bag for up to 1 month. Then thaw at room temperature before serving.
Best Containers for Freshness
Use a tight fitting container to keep air out. This step helps maintain softness and flavor.
