Gluten Free Strawberry Rhubarb Crumble with Almond Oat Topping

Few desserts hit the way a bubbling fruit crumble does straight from the oven, and this one delivers that same cozy magic without a speck of wheat flour in sight. The filling leans into the natural tartness of rhubarb balanced against sweet strawberries, with arrowroot starch doing the thickening work and a little fresh ginger adding a bright, unexpected warmth. What makes this crumble genuinely special is the topping — rolled oats, almond flour, and sliced almonds come together with coconut oil and maple syrup to form golden, clumpy clusters that bake up crisp and deeply nutty. Arrowroot is a reliable swap for cornstarch or flour-based thickeners, so the filling sets up beautifully without any gummy texture or starchy aftertaste. The whole thing is sweetened entirely with maple syrup, which gives the fruit layer a subtle caramel depth that white sugar just can't match. After 40-plus minutes in the oven, the edges bubble vigorously and the topping turns a deep, toasty brown that's almost impossible to resist. Let it rest just long enough for the filling to thicken, then serve it warm — ideally with a scoop of your favorite vanilla ice cream melting into the cracks.
