A crisp of sliced rhubarb and fresh raspberries with sugar, cornstarch, and vanilla, topped with a crumble of oats, brown sugar, cinnamon, and melted butter. Baked until golden and bubbling.
The moment this crisp comes out of the oven, the kitchen smells like a berry patch in spring. Four cups of sliced rhubarb and fresh raspberries tossed with sugar, cornstarch, and vanilla, baked under a crumble of rolled oats, flour, brown sugar, cinnamon, and melted butter. At 350°F (175°C) for forty-five minutes, the fruit bubbles up around the edges and the topping turns golden and crunchy.
The rhubarb is tart enough to stand up to the sweet crumble. The raspberries dissolve into a jammy sauce between the rhubarb pieces. A scoop of vanilla ice cream on top melts into the hot fruit and turns into a warm-cold, sweet-tart pool. We keep making this on repeat when rhubarb is in season.
Tips for Making Raspberry Rhubarb Crisp
Cut the rhubarb into even pieces
Half-inch slices cook evenly. Larger pieces stay crunchy in the centre while the rest turns to mush.
Fresh rhubarb is best. If using frozen, do not thaw it. Add an extra tablespoon of cornstarch to account for the extra liquid.
Make the crumble topping by hand
Mix oats, flour, brown sugar, cinnamon, and salt in a bowl. Pour in the melted butter and stir until everything is clumpy and coated.
Do not press the topping down. Drop it in rough clumps over the fruit. Loose crumble bakes crunchier than a packed layer.

Frequently Asked Questions
Can I use other fruit?
Strawberries, blackberries, or blueberries all work in place of raspberries. The rhubarb is harder to substitute. Without it, the crisp is sweeter and less complex.
Do I need to peel the rhubarb?
No. The skin is edible and softens during baking. Just trim the ends and slice.
Can I make this ahead?
Assemble the fruit in the dish and the crumble separately. Refrigerate both. Top and bake when ready. The crisp is best served within a few hours of baking.
