Step-by-step directions

Let’s get baking! These easy steps will help you whip up a batch of perfectly balanced, sweet-tart rhubarb cookies.

Prep the rhubarb and ingredients

Wash and dry the rhubarb, then trim the ends and cut it into small ¼-inch pieces. If your rhubarb is extra tart, toss it with a teaspoon of sugar and let it sit for 10 minutes to mellow the acidity. Meanwhile, measure and set out all ingredients, allowing the butter to soften at room temperature and the egg to come to room temperature for better mixing.

In a large mixing bowl, beat together softened butter, granulated sugar, and brown sugar until the mixture is light, fluffy, and irresistibly smooth—about 2 minutes. Add the egg and vanilla extract, mixing until everything is well combined and creamy. In a separate bowl, whisk together the flour, baking soda, salt, and a pinch of cinnamon (because why not add a little extra warmth?). Gently fold the dry ingredients into the wet mixture, stirring just until everything comes together. No overmixing! That’s the secret to keeping your cookies soft, tender, and perfectly chewy.

Fold in the rhubarb and add-ons

Gently fold in the chopped rhubarb with a spatula, distributing it evenly without overmixing. If using optional add-ins like white chocolate chips or nuts, fold them in at this stage. The dough will be slightly soft but should hold its shape.

Scoop and chill the dough

Use a cookie scoop or tablespoon to portion the dough onto a parchment-lined baking sheet, leaving about 2 inches of space between each cookie. To achieve the best texture and prevent excessive spreading, refrigerate the scooped dough for at least 30 minutes. Short on time? A quick 10-minute chill in the freezer will do the trick!

Bake and cool

Preheat the oven to 350°F (175°C) and bake the cookies for 10–12 minutes, until the edges turn lightly golden while the centers stay soft and irresistibly chewy. Let them rest on the baking sheet for 5 minutes so they firm up just right before moving them to a wire rack to cool completely. If you’re adding a sprinkle of coarse sugar, now’s the time—while they’re still warm—for that perfect, delicate crunch. Once cooled, they’re ready to enjoy.

Customization and variations

Switch the flour: use almond flour for a slightly nutty, gluten-free alternative or oat flour for a chewier texture.
Adjust the sweetness: swap some of the sugar for honey or maple syrup for a richer, deeper flavor.
Add citrus flair: mix in orange zest instead of lemon for a sweeter citrus touch.
Make it dairy-free: replace butter with coconut oil and use a flax egg for an entirely plant-based version.
Boost the texture: add shredded coconut or rolled oats for extra chewiness.
Chocolate lovers’ twist: add dark chocolate chunks for a rich, bittersweet contrast to rhubarb’s tartness.
Try a nutty crunch: mix in chopped pecans, almonds, or hazelnuts for added depth.
Spiced kick: add a pinch of ground ginger or nutmeg for warmth.

Servings and pairings

Pair with a warm drink: these cookies go beautifully with a cup of hazelnut coffee or a soothing lemon balm drink.
Serve with fresh fruit: balance the tartness with sliced strawberries or blueberries on the side.
Ice cream sandwich hack: sandwich vanilla or cinnamon ice cream between two cookies for a summer treat.
Drizzle with citrus glaze: mix powdered sugar with fresh lemon juice for a bright, tangy finish.
Enjoy with Greek yogurt: serve these cookies alongside a bowl of Greek yogurt with a drizzle of honey for a balanced, satisfying treat.
Crumble over oatmeal: crush a cookie over warm oatmeal or yogurt for a crunchy, flavor-packed topping.

Frequently asked questions

Is rhubarb a superfood?

Definitely! Rhubarb is packed with antioxidants, fiber, and vitamins. Its anthocyanins and polyphenols support heart health, fight inflammation, and make it a great, low-calorie addition to a balanced diet.

Why is rhubarb used in baking?

Do I need to peel rhubarb before baking?

No, peeling rhubarb isn’t necessary. The thin skin contains nutrients and helps maintain the structure during baking. However, if the stalks are very thick or fibrous, you can peel away the outer layer for a smoother texture

Should you soak rhubarb before baking?

Soaking is not required, but macerating rhubarb (tossing it with a little sugar and letting it sit) can help mellow its tartness and draw out excess moisture. If using frozen rhubarb, draining off excess liquid after thawing can prevent soggy baked goods.

How do you sweeten rhubarb without sugar?
