Ingredients
1 cup light brown sugar
1/2 cup butter, softened
1 teaspoon vanilla extract

1 3/4 cups all-purpose flour
1 teaspoon cinnamon

Step-by-Step

- In a separate bowl, whisk together the flour, cinnamon, salt, baking soda, and baking powder.
- Gradually add the dry ingredients to the wet, mixing on low just until combined. Don’t overmix—stop when the dough comes together.

- Scoop tablespoon-sized rounds of dough onto the prepared baking sheets, leaving 2 inches of space between each cookie.

- Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.

What to Serve Brown Sugar Rhubarb Cookies With

Top Tips for Perfecting
- Rhubarb tip: If rhubarb is out of season, frozen rhubarb works just fine—just thaw and pat dry to avoid soggy dough.
- Spice variations: Try adding a pinch of ginger or nutmeg for an even spicier kick.
- Butter matters: Use real butter for the best flavor and texture; margarine just isn’t the same.
- Watch the bake: These cookies are best slightly underbaked so they stay soft and chewy. Don’t wait for them to brown completely.
- Dough chilling: For thicker cookies, chill the dough for 30 minutes before baking.
Feel free to experiment—baking is about making it your own!
Storing and Reheating Tips
Keep your Brown Sugar Rhubarb Cookies fresh by storing them in an airtight container at room temperature for up to 4 days. To freeze, place cooled cookies in a single layer in a zipper bag or airtight container and freeze for up to 2 months. Thaw at room temperature or pop them in a 300°F oven for 3-4 minutes for that “fresh-baked” warmth. If you plan to freeze unbaked dough, scoop and freeze dough balls—then bake straight from the freezer, adding an extra minute or two to the baking time.
FAQs
Can I substitute another fruit for rhubarb?
Absolutely! Strawberries or chopped apples work well, though the flavor will be less tart.
Is it necessary to peel the rhubarb before using?
No need—just wash and trim it. Peeling isn’t required unless the skin is very tough.
Can I use dark brown sugar?
Yes, dark brown sugar brings a deeper molasses note, but your cookies may be a touch denser.
What if I don’t have cinnamon?
You can skip it, but it’s highly recommended. Try nutmeg or cardamom for a different twist.
Why are my cookies spreading too much?
This often means the butter was too soft or the dough is too warm. Chilling the dough for 30 minutes will help.
