*A detailed and printable recipe card is available at the bottom of this post.
Crisp topping
You’re going to add all the dry ingredients to the bowl of a stand mixer fitted with a paddle attachment. Add in the butter pats and mix until it is nice and crumbly. Pro tip: no stand mixer? Use a hand-held pastry cutter.
Strawberry Rhubarb Fruit Filling
Slice the strawberries into quarters, place them in a bowl and sprinkle with 2 tbsp of sugar. Stir to combine and set aside.
Slice your rhubarb into 1/4 inch pieces, place them in a bowl and sprinkle with the remaining sugar. Stir to combine and set aside for 20 minutes.
Scoop the rhubarb out and add it to the bowl with the strawberries. You can use a slotted spoon to transfer or just gently drain off any rhubarb juice from the bowl. Dips on “Rhubarb Juice” as a band name.
Gently toss the strawberry/rhubarb mixture with lemon juice, cornstarch, and almond extract. Add to a buttered 9×13 or 8×8 baking dish. Top with the gluten free crisp topping.
Bake until the crisp is lightly browned, the fruit is bubbly, and your house smells like the farts of unicorns. *see recipe card for actual temps and times. 🙂
Pro tips/recipe notes
- You can grind oats in a food processor to make “oat flour” if you don’t have any other gluten-free flour on hand.
- Sub in coconut oil or your favorite non-dairy butter to make this dairy-free or vegan.
- To reheat, you can microwave individual portions, or reheat the whole batch in the oven at 200 degrees for 15 minutes.
- If using frozen fruit (related: freezing strawberries), drain off half of the liquid when it defrosts.
Can I Prepare This Rhubarb Crisp Ahead of Time?
Yes! Prep and store the fruit and crisp topping separately. Drain off any excess liquid from the fruit and place in a baking dish and then top with the crumble.
How to Store Gluten Free Crisp
If you actually have leftovers (unlikely), you can keep this rhubarb crumble recipe (covered) at room temperature for a day. After that, I would transfer it to the fridge. If your summer kitchen has a fruit fly problem (aholes with tiny wings), store it in the fridge immediately.
You can keep some of the crisp topping in an air-tight container in the fridge for up to a week or freeze for six months. No need to defrost before baking.

A friend made this recipe for me recently and it was so good we fought over the leftovers! Delicious served warm with a scoop of vanilla ice cream, and equally good with a bit of yoghurt for breakfast the next day. Definitely making this one again!J
