Rhubarb Cookies Recipe

If you’re craving the taste of early summer and a cozy, home-baked treat, you simply have to try these Rhubarb Cookies! They’re soft, gently tart, and absolutely irresistible—especially with that swoon-worthy cream cheese frosting on top. Nothing captures the magic of rhubarb season like these beautiful cookies that balance sweetness and tang in every single bite.

Ingredients You’ll Need

The beauty of these cookies is how simple and accessible the ingredients are! Each component brings its own special magic—whether it’s the moisture of the rhubarb, the rich flavor of brown sugar, or the gentle bite of coconut or oats. Here’s a look at what you’ll need and why it matters.

• Butter (softened): Provides a rich base and that soft, tender crumb everyone loves in homemade cookies.
• Brown sugar: Adds warmth, chewiness, and caramel notes that perfectly complement tart rhubarb.
• Eggs: Bind everything together for structure and an extra bit of richness.
• Flour: The foundation for a sturdy-yet-tender cookie with just the right amount of lift.
• Baking soda: Helps the cookies puff up and stay soft (not flat or tough!).
• Salt: Just a pinch sharpens all the flavors and keeps things from tasting flat.
• Diced rhubarb: The star of the show—its tartness pops in every bite and keeps the cookies wonderfully moist.
• Flaked coconut or old fashioned oats: Pick your favorite! Coconut adds chew and a hint of tropical flavor, while oats make things hearty and comforting.
• Cream cheese: For the dreamy, tangy frosting that’s essential (trust me, don’t skip it!).
• Powdered sugar: Blends into the cream cheese for a smooth, sweet-as-clouds topping.
• Vanilla extract: Adds warmth and depth to the frosting—makes it irresistible.

Variations

One of my favorite things about baking is making a recipe your own. Rhubarb Cookies are endlessly adaptable—tweak them to use what you have, accommodate allergies, or just suit your mood. Give one of these tasty variations a try!

• Go Nutty: Fold toasted pecans or walnuts into the dough for extra crunch and earthy flavor.
• Add Citrus Zest: A sprinkle of orange or lemon zest in the batter or frosting lifts the whole cookie with bright, zippy freshness.
• Swap Coconut for Oats (or vice versa): Choose oats for a classic, heartier texture or coconut for chewier, slightly exotic results.
• Make Them Gluten-Free: Use a trusted 1:1 gluten-free flour blend and certified gluten-free oats for cookies everyone can enjoy.
• Berry Burst: Swap out a third of the rhubarb for chopped berries (like strawberries or raspberries) for a sweeter, colorful twist.

How to Make Rhubarb Cookies

Step 1: Cream the Butter and Sugar

Start by beating your softened butter and brown sugar together until the mixture is light and fluffy—this is what makes the cookies soft and beautifully tender. Don’t rush it; give it a good three to five minutes, scraping down the sides if needed.

Step 2: Add the Eggs

Crack in the eggs one at a time, mixing until each is well incorporated. The batter will look luscious, shiny, and thick at this stage—just the way you want it.

Step 3: Mix in the Dry Ingredients

In a separate bowl, whisk together your flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, mixing just until combined—don’t overmix, or your cookies may turn out dense.

Step 4: Fold in Rhubarb and Coconut (or Oats)

Gently stir in the diced rhubarb and your add-in of choice. The dough will be thick and generously studded with tart, juicy rhubarb and whichever tasty texture you picked!

Step 5: Scoop and Bake

Drop tablespoon-sized mounds of dough onto a greased or parchment-lined baking sheet. Give them some space! Bake at 350°F for 10–12 minutes, or until the cookies are just golden at the edges and set in the middle.

Step 6: Make and Spread the Frosting

While your cookies cool completely, whip up the frosting by beating softened cream cheese until fluffy, then adding powdered sugar and vanilla until you have a silky, spreadable topping. Frost each cookie generously—and try not to eat too much as you go!

How to Serve Rhubarb Cookies

Garnishes

The easiest way to make these cookies extra pretty? Sprinkle a bit of extra flaked coconut, a dusting of powdered sugar, or even a few shreds of lemon zest on top of the still-tacky frosting. A slice of fresh rhubarb or a dried edible flower will also make these treats pop at a party!

Side Dishes

Of course, Rhubarb Cookies are stars on their own, but they’re lovely alongside a scoop of vanilla ice cream, a glass of lemony iced tea, or a big mug of coffee or cocoa. They’re also fabulous set out with a platter of fresh fruit for a summery afternoon snack spread.

Creative Ways to Present

Looking to impress? Stack frosted cookies tall on a pretty cake stand, or pack them in wax paper-lined boxes for sweet homemade gifts. For brunch, serve mini cookies on toothpicks with berries, or turn them into ice cream sandwiches—simply freeze a spoonful of ice cream between two cookies and swoon!

Make Ahead and Storage

Storing Leftovers

You can store Rhubarb Cookies (frosted or unfrosted) in an airtight container in the refrigerator for up to five days. If they’re stacked, place parchment or wax paper between layers so the frosting stays neat and luscious.

Freezing

To freeze, place unfrosted cookies in a single layer on a baking sheet until solid, then transfer to a zip-top bag or container. They’ll stay fresh for up to 3 months. For best results, freeze the frosting separately and spread on thawed cookies.

Reheating

No need to reheat if serving at room temp, but if you prefer them slightly warm (unfrosted), pop cookies in a 300°F oven for a few minutes to revive that fresh-baked magic. Allow frosted cookies to come to room temperature before enjoying for the best texture.
