I bake this rhubarb crisp when the warm weather hits. Tangy stalks tucked under a buttery oat blanket fill the house with sweet smells. It’s an easy favorite and everyone is happy to dive in after supper when it’s golden and bubbling.
When I was a teenager learning how to bake, this was my top pick for potlucks with family. It’s the one I still carry to picnics, and every time someone races to snag the last bit.
Tasty Ingredients
- Whole wheat or all purpose flour: Use either for the topping—whole wheat brings nuttiness, all purpose is classic
- Rolled oats: Old fashioned oats give you that perfect crunchy layer, skip the quick kinds since they go soggy
- Brown sugar: Pack it lightly for that deep caramel kick, make sure it’s soft and lump-free
- Cold butter, cubed: Real butter chopped cold gives that bakery crunch on top, slice fresh for the best flakes
- Corn starch: Thickens things up—choose gluten free if you want. Add less if you’re using fresh rhubarb since there’s less liquid than frozen
- Granulated sugar: White sugar brings out the sweetness and tames the tang
- Chopped rhubarb: Fresh or straight-from-the-freezer both work. Stalks should be crisp and bright red—skip any soft or squishy ones
Mouthwatering Step-By-Step
- Cool and serve:
- Take your pan out and let it chill at least 10 minutes to help thicken the juices. Scoop into bowls while warm—don’t skip a scoop of vanilla ice cream if you want to go all out!
- Assemble and bake:
- Scatter the topping right over the rhubarb mix. Press down ever so lightly—don’t squish too hard or you lose the crunch. Slide it into the center rack of your oven. Bake 35 to 40 minutes till edges bubble and the top turns golden with crisp bits.
- Make the topping:
- Mix the oats, flour, brown sugar, and butter (cold chunks!) in a fresh bowl. Use your fingers, a pastry blender, or fork, and work quick so you get a crumbly, clumpy texture with some larger buttery pieces.
- Mix the filling:
- Blend up your rhubarb pieces with white sugar and corn starch—toss so each chunk is shiny and covered. If using fresh stems, use a little less starch. Spread out in your greased pan so it’s nice and even.
- Prepare your pan:
- Butter up your baking dish or swipe it with mild oil—pay special attention to the corners so the filling doesn’t catch

Rhubarb always takes me straight back to Grandma’s garden patch. We’d cut big crimson stalks and wait for her to pull out the bubbling crisp from the oven. Her trick—let the topping bake long enough for a deep crunch—and I stick to it every year.
Keeping It Fresh
Allow any leftovers to cool off completely before you cover with foil or seal in a lid. Pop in the fridge and eat within three days for best taste. If you want the topping to stay crispy, use the oven to reheat instead of the microwave.
Swaps and Variations
Make it gluten free with your favorite blend. Rolled oats? Certified gluten free if needed. Got allergies? There’s no nuts here. Not much rhubarb or want a milder flavor? Toss in some sliced apples or strawberries too.
Fun Ways to Serve
Enjoy it straight from the oven, cooled to room temp, or even breakfast-style over a bowl of yogurt. Whipped cream makes it extra special and I’m always happy with a scoop of vanilla or honey ice cream melting on top.

Story and Traditions
While rhubarb pops up first in spring gardens, did you know it’s really a veggie not a fruit? It’s been loved in Europe and North America for generations. That tart kick is just what makes it shine in pies and sweet, bubbly crisps.
Frequently Asked Questions
- → Can I use fresh or frozen rhubarb?
Totally! Both are fine. Just cut back on corn starch if you’re using fresh rhubarb—frozen needs the extra to soak up liquid.
- → What is the best way to create a crumbly topping?
Stick with cold butter cut in pieces. Mash it into the dry stuff with a pastry cutter or a fork till you see crumbles.
- → Can I substitute the flour?
Sure thing. Go with all-purpose or whole wheat—whatever you’ve got works just fine.
- → Why should I let the crisp cool before serving?
If you wait, the filling firms up so it’s a breeze to scoop out and the taste gets even better. Plus, you won’t burn your mouth!
- → How can I serve this dessert?
It’s great warm with vanilla ice cream on top or plop on some whipped cream if you feel fancy.
