Name: Cinnamon Rhubarb Crisp for Two
Prep time: 10 min
Cook time: 15 min
Total time: 25 min
Yield: 4
Ingredients: 1 3/4 cups rhubarb (cut into 1/2-inch pieces for even cooking); 3/4 cup sugar (I use Domino granulated sugar); 2 tbsp flour; 1/4 tsp cinnamon; 1 pinch ground nutmeg; 3 tbsp oats (I prefer Quaker Old Fashioned Oats for a heartier texture); 4 tbsp flour; 3 tbsp brown sugar; 3 tbsp pecans (chopped into 1/4-inch pieces); 2 1/2 tbsp butter (cold and cut into small cubes)

If you ask me, rhubarb crisp is one of those desserts that just hits different when you make it for two.

This small-batch version gives you all the sweet-tart rhubarb filling with a buttery, crunchy topping without leftovers sitting around for days. The rhubarb gets tender and jammy while the oat and pecan topping turns golden brown.

It comes together with simple pantry staples and bakes up in individual portions. A little cinnamon and nutmeg warm things up, while the brown sugar adds a nice caramel note to the crumble.

It’s the kind of dessert that feels special but doesn’t require you to make a whole 9×13 pan.

Why You’ll Love This Rhubarb Crisp

Perfect portion size – This recipe makes just enough for two people, so you won’t have leftovers sitting around or feel tempted to overindulge.
Quick and easy – Ready in under 35 minutes, this dessert comes together fast when you’re craving something sweet but don’t want to spend all evening in the kitchen.
Simple ingredients – You probably have most of these pantry staples on hand already, making this an easy last-minute dessert.
Great way to use fresh rhubarb – If you’ve got rhubarb growing in your garden or found some at the farmers market, this crisp is the perfect way to enjoy it without making a huge batch.

What Kind of Rhubarb Should I Use?

Fresh rhubarb is always your best bet for this recipe, and you’ll find it at most grocery stores during spring and early summer. The color of the stalks can range from deep red to pale pink or even greenish, and while the red stalks look prettier, they all taste pretty much the same. Just make sure to trim off any leaves since they’re actually toxic, and stick to using only the stalks. If fresh rhubarb isn’t available, frozen rhubarb works just fine too – no need to thaw it first, just add a few extra minutes to your baking time.

Options for Substitutions

This cozy dessert is pretty forgiving when it comes to swaps:

Rhubarb: Fresh rhubarb is best here, but if you only have frozen, that works too. Just thaw it first and drain any excess liquid before using. You can also mix in some strawberries or apples with the rhubarb for a different flavor.
Pecans: Any nuts you have on hand will work great in the topping. Try walnuts, almonds, or even hazelnuts. If you’re not a nut person, just leave them out or add extra oats instead.
Brown sugar: Regular white sugar works fine in the topping if that’s what you have. You’ll lose a bit of that caramel-like flavor, but the crisp will still taste good.
Butter: Coconut oil can replace the butter in the topping if you need a dairy-free option. Use the same amount and make sure it’s solid, not melted.
Oats: Quick oats and old-fashioned oats both work here. Just stick with one or the other – don’t use instant oats as they’ll get too mushy.

Watch Out for These Mistakes While Baking

The biggest mistake when making rhubarb crisp is cutting the rhubarb pieces too large or too small – aim for consistent half-inch chunks so they cook evenly and don’t turn to mush or stay too firm.

Many people skip greasing the baking dishes, which makes serving a nightmare, so take that extra minute to butter them well or you’ll be scraping dessert off the sides.

Another common error is not placing the dishes on a baking tray, which is actually important because rhubarb releases a lot of juice that can bubble over and make a mess in your oven.

To get a perfectly golden, crispy topping instead of a pale one, make sure your butter is cold when you blend it into the oat mixture – this creates those nice crumbly bits that brown beautifully in the oven.

What to Serve With Rhubarb Crisp?

The best way to serve rhubarb crisp is warm from the oven with a big scoop of vanilla ice cream melting on top. The cold, creamy ice cream mixed with the warm, tart rhubarb and crunchy topping is absolutely perfect. If you’re not an ice cream person, a dollop of fresh whipped cream or even some plain Greek yogurt works great too. For an extra special touch, you could drizzle a little caramel sauce over the whole thing or serve it alongside a hot cup of coffee for a cozy dessert.

Storage Instructions

Store: Keep any leftover rhubarb crisp covered with plastic wrap or foil in the fridge for up to 3 days. The topping might lose a bit of its crunch, but it still tastes great. I actually don’t mind eating it cold straight from the fridge for breakfast the next day!

Freeze: You can freeze the crisp in an airtight container for up to 2 months. Just let it thaw in the refrigerator overnight before reheating.

Warm Up: To bring back that fresh-baked taste, reheat individual portions in the microwave for about 30 seconds, or pop the whole dish in a 350°F oven for 10-15 minutes. This helps crisp up the topping again and makes the filling nice and bubbly.

Ingredients

For the fruit base:

1 3/4 cups rhubarb (cut into 1/2-inch pieces for even cooking)
3/4 cup sugar (I use Domino granulated sugar)
2 tbsp flour
1/4 tsp cinnamon
1 pinch ground nutmeg

For the topping:

3 tbsp oats (I prefer Quaker Old Fashioned Oats for a heartier texture)
4 tbsp flour
3 tbsp brown sugar
3 tbsp pecans (chopped into 1/4-inch pieces)
2 1/2 tbsp butter (cold and cut into small cubes)

Step 1: Prepare the Oven and Dishes

Preheat your oven to 375°F and lightly grease two small baking dishes (6-8 ounce ramekins or similar).

This ensures even browning and easy serving when the crisp is finished.

Step 2: Prepare the Rhubarb Filling

1 3/4 cups rhubarb
3/4 cup sugar
2 tbsp flour
1/4 tsp cinnamon
1 pinch ground nutmeg

Cut the rhubarb into ½-inch pieces and place in a bowl.

Add the granulated sugar, 2 tablespoons flour, cinnamon, and nutmeg, then gently toss until the rhubarb is evenly coated.

The sugar will begin to draw out the rhubarb’s juices, creating a lightly sweetened filling as it bakes.

Step 3: Make the Crisp Topping

3 tbsp oats
4 tbsp flour
3 tbsp brown sugar
3 tbsp pecans
2 1/2 tbsp butter

In a separate bowl, combine the oats, 4 tablespoons flour, brown sugar, and chopped pecans.

Add the cold butter cubes and work them into the dry mixture using your fingertips or a fork, breaking them down until the mixture resembles coarse breadcrumbs.

I find that keeping the butter cold and working quickly prevents it from becoming greasy, which gives you a better texture in the baked crisp.

Step 4: Assemble and Bake

Divide the rhubarb mixture from Step 2 evenly between the two prepared dishes.

Top each with half of the crisp topping from Step 3, distributing it evenly and gently pressing it down slightly so it bakes into a cohesive crust.

Place the dishes on a baking sheet and bake at 375°F for 18-20 minutes, until the topping is golden brown and the filling bubbles slightly at the edges.

Step 5: Cool and Serve

Remove the crisps from the oven and let them cool for 5-10 minutes before serving.

I like to serve them slightly warm with a dollop of vanilla ice cream or whipped cream—the warmth helps the topping stay crispy while the cold dairy provides a nice contrast.
