Single Serve Rhubarb Crisp

5 from 1 vote

I’m a massive fan of rhubarb, as well as almost anything sour, and there is just something about a crisp that screams “LOVE YOURSELF,” ya know? So when I had a little extra rhubarb leftover from the farmers market, I thought, “Yeah, we’re gonna make a single serve rhubarb crisp.”

After my cousin made a strawberry rhubarb pie once, I was immediately in love and have been forever hunting down anything and everything in between. While spring and summer aren’t necessarily the months for cozy recipes, I prefer to be cozy year-round (and rhubarb season is in the warmer months).

So basically, any time is the perfect time for a little crisp.

SINGLE SERVE RHUBARB CRISP

The crisp itself is made of a gooey rhubarb filling and a buttery oat crumble on top. I used a mini cast iron, but you can also use a ramekin if that’s what you have on hand.

The rhubarb softens as it cooks, giving you the coziest mini crisp you ever did see. If you’re looking for a little sweet but sour treat, this is for you!

What dish can I use if I don’t have a mini cast-iron skillet? Any 6-inch oven-safe dish will work for this recipe! You just want it to have at least an inch or two of depth in the pan. If you have two smaller ramekins, you can split this between them as well!

INGREDIENTS

  • Rhubarb: The fruity star of the show
  • Sugar: Some sweet to balance the sour and help thicken the filling
  • Cornstarch: Brings together the juices to make a gooey base
  • Lemon Juice: Works with the fruit, sugar, and cornstarch for the perfect flavor and texture
  • Butter: Adds flavor and a smooth finish to both the filling and the crumble topping
  • Traditional Oats: For a little extra texture
  • Flour: Binds together your crisp and soaks up any excess moisture
  • Brown Sugar: For a deeper flavor
  • Cinnamon: To bring that cozy spice
  • Salt: Balances out the sweet and brings out the various flavors

What’s the difference between a crisp and a cobbler? The bases of both are fairly similar, and you’ll often find both without a pie crust. The main difference is the topping. A crisp is often topped with something crunchier, like a streusel, while a cobbler has a more biscuit-like finish (sometimes it is actually a biscuit dough).

HOW TO MAKE A SINGLE SERVE RHUBARB CRISP

Preheat your oven to 350°F and lightly grease your oven-safe baking dish. 

In a bowl, make your rhubarb filling by whisking together your sugar and cornstarch to remove any clumps. Then add in your chopped rhubarb and lemon juice and give it a stir.

Add your filling to your pan, smooth into an even layer, and dot with butter.

For your crisp topping, combine your oats, flour, brown sugar, cinnamon, and salt in a bowl. Rub your butter into your mixture using your fingers, until it’s just crumbly.

Top your rhubarb filling in your pan with your crumble and place in the oven to bake for 20-30 minutes. Your crisp is baked when the top is golden, and the filling is bubbly.

Once you remove your baked single serve rhubarb crisp from the oven, allow it to cool for at least 10 minutes before eating! Serve as-is or with a scoop of vanilla ice cream.

TIPS & VARIATIONS

  1. Adjust with any fruit you please, blueberries, apples, or even mix and match! I did mention how much I loved strawberries and rhubarb together, didn’t I?
  2. You can omit the cinnamon in the crumble if you prefer, or swap it in for another spice. Cardamom would be delicious!
  3. A scoop of vanilla ice cream on top pairs perfectly with the cinnamon in this crisp and makes for a cool and smooth bite

STORING YOUR MINI RHUBARB CRISP

For any leftovers, store in an airtight container at room temperature for 3 days or up to 5 days in the refrigerator. To note, the crisp will soften the longer it sits, so if you prefer a really crispy exterior, eat it straight away!
