Sugar Rhubarb Cookies are a sweet and cheerful celebration of the short-but-glorious rhubarb season. These cookies strike the perfect balance: the buttery richness you crave, the signature tang of rhubarb, and a crackly sugar coating that sparkles with every bite. The result is a tender, nostalgia-inducing treat that feels just as at home with a cup of afternoon tea as it does as an after-dinner sweet. If you’ve never baked with rhubarb before, you’re in for an utter delight!

Ingredients You’ll Need
This delightful batch of cookies comes together using simple pantry staples and the magical pop of fresh rhubarb. Each ingredient plays its part, from flavor to texture to that irresistible cookie crumb—trust me, nothing here is optional if you want picture-perfect Sugar Rhubarb Cookies!
- 1 cup sugar: Sweeter than just about any other ingredient here, it balances rhubarb’s tartness and makes the cookie tops crackle.
- ½ cup unsalted butter, softened: Brings that classic cookie richness and helps create a soft, tender dough that melts in your mouth.
- 1 large egg: Binds the mixture together and gives the cookies their lovely cake-like lift.
- 1 tsp vanilla extract: Adds depth and a warm, bakery-fresh aroma that pairs perfectly with rhubarb.
- 1 ½ cups all-purpose flour: Provides structure to keep these cookies delightfully chewy, not cakey.
- ½ tsp baking soda: Just enough to ensure a lightness for those sought-after slightly puffed centers.
- ¼ tsp salt: A pinch that brings all the flavors into sharper, sweeter focus.
- ¾ cup finely chopped fresh rhubarb: The star ingredient—tart, pink-flecked bursts in every bite!
- Extra sugar for rolling: Don’t skip this step; the glittery crust offers satisfying crunch and extra sweetness.
How to Make Sugar Rhubarb Cookies
Step 1: Mix the Butter and Sugar
Start by creaming together the softened butter and sugar in a large bowl. Beat until the mixture looks pale and fluffy; this will set the stage for light, tender cookies. Don’t rush it—giving a little extra time here ensures that signature soft-cookie crumb!
Step 2: Add Egg and Vanilla
Crack in the egg and add the vanilla extract, beating again until everything is smooth and uniform. The egg helps bind the ingredients, while the vanilla infuses that lovely, homey aroma into your Sugar Rhubarb Cookies.
Step 3: Combine the Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, and salt. Mixing dry ingredients first guarantees even distribution—no bitter bites from uneven baking soda, just perfectly balanced cookies from edge to center.
Step 4: Bring It All Together
Add your whisked dry ingredients to the wet mixture, beating gently until just combined. This is the moment those classic cookie dough dreams come true. Fold in the chopped rhubarb by hand, taking care not to overmix—those gorgeous pink flecks are the treasure of these Sugar Rhubarb Cookies.
Step 5: Shape and Sugar Coat
Scoop out dough balls (about 1.5 tablespoons each) and gently roll them between your palms. Next, toss each dough ball in extra sugar until sparkling. This simple step gives the finished cookies their irresistible crunchy finish and sweet first impression.
Step 6: Bake to Perfection
Arrange your sugared dough balls on a parchment-lined baking sheet, leaving room for spreading. Bake at 350°F (175°C) for 10–12 minutes—watch for golden edges and barely set centers. Let them cool slightly before transferring to a rack so they stay intact and tender.
How to Serve Sugar Rhubarb Cookies

Garnishes
Sometimes, the simplest garnish is the best—think a dusting of powdered sugar or a drizzle of white chocolate. If you love a little extra color, scatter thinly sliced ribbons of rhubarb on top for a bakery-worthy look. The sugar coating already adds sparkle, but don’t be afraid to get creative with your finishing touches on these Sugar Rhubarb Cookies!
Side Dishes
Sugar Rhubarb Cookies pair beautifully with a scoop of vanilla ice cream for a slightly decadent dessert, or try serving them alongside a tart lemon or raspberry sorbet for a bright, palate-refreshing contrast. Of course, a cozy mug of tea or creamy latte makes them feel right at home at any hour.
Creative Ways to Present
Stack these cookies on a tiered cake stand for a vintage tea party vibe, or tuck a few into parchment and tie with twine for adorable edible gifts. For brunch gatherings, try making mini versions and serving them alongside mimosas—these Sugar Rhubarb Cookies are guaranteed conversation starters wherever they go!
Make Ahead and Storage
Storing Leftovers
Keep your leftover Sugar Rhubarb Cookies in an airtight container at room temperature. They’ll stay fresh for up to 3 days, though their edges may soften over time. Layer parchment paper between cookies to help maintain their sugar-crusted tops and prevent sticking.
Freezing
These cookies freeze beautifully! Pop cooled cookies into a freezer-safe bag and store for up to two months. Just let them come to room temperature or warm briefly for that just-baked magic. You can also freeze dough balls—simply roll them in sugar first, then freeze and bake straight from frozen for a freshly baked treat any time.
Reheating
To recapture that fresh-from-the-oven scent and texture, warm Sugar Rhubarb Cookies in a 300°F (150°C) oven for 3–4 minutes. This will revive their edges and bring out that wonderful bakery aroma that makes every bite irresistible.
FAQs
Can I use frozen rhubarb?
Absolutely! If you use frozen rhubarb, be sure to thaw and drain it thoroughly to avoid a soggy dough. Chop it finely, just as you would with fresh.
What if I don’t have extra sugar for rolling?
While the sugar coating adds a delightful crunch and sparkle, you can skip it in a pinch. The cookies will still taste delicious, but you may miss out on that signature crisp top.
Can I substitute another fruit for rhubarb?
Sure! Finely chopped tart apples or berries can work if rhubarb isn’t available, though you’ll lose some of the tangy bite that defines Sugar Rhubarb Cookies. Adjust the sugar slightly if your substitute fruit is naturally sweeter.
Why do my cookies spread too much?
Over-softened butter or a warm kitchen can make the dough a bit loose. Chill the shaped dough balls for 10–15 minutes before baking to help the cookies hold their shape.
How can I make my cookies more tart?
Add a little extra rhubarb or reduce the sugar by a tablespoon or two. Just be mindful that too much extra moisture (from more rhubarb) can throw off the texture, so adjust carefully and enjoy tweaking your perfect batch of Sugar Rhubarb Cookies!
