Ingredients

Scale
  • 4 cups fresh rhubarb, chopped into 1/2-inch pieces (about 480 grams or 1.06 pounds)
  • 3/4 cup granulated sugar (150 grams)
  • 1 tablespoon cornstarch
  • 1 teaspoon vanilla extract
  • 1 tablespoon fresh lemon juice
  • 1 cup almond flour (100 grams)
  • 1/2 cup gluten-free rolled oats (45 grams)
  • 1/3 cup sliced almonds (35 grams)
  • 1/3 cup brown sugar, packed (65 grams)
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 6 tablespoons unsalted butter, melted (85 grams)

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. In a large bowl, combine the chopped rhubarb, granulated sugar, cornstarch, vanilla extract, and lemon juice. Stir gently but thoroughly to coat the rhubarb evenly.
  3. Transfer the filling to your baking dish and spread it out evenly, smoothing the top with a spatula.
  4. In a medium bowl, whisk together almond flour, gluten-free oats, sliced almonds, brown sugar, cinnamon, and salt.
  5. Pour the melted butter over the dry ingredients and mix with a wooden spoon until the mixture clumps together into crumbly clusters. Add more melted butter if needed to hold together.
  6. Sprinkle the crumble evenly over the rhubarb filling.
  7. Bake for 35-40 minutes until the topping is golden brown and the rhubarb is bubbling around the edges.
  8. Cool slightly for 10 minutes before serving to allow the filling to thicken.

Notes

If the crumble browns too quickly, tent loosely with foil for the last 10 minutes of baking. For a less tart filling, add an extra tablespoon of sugar before baking. Cornstarch can be substituted with arrowroot powder. For vegan versions, replace butter with coconut oil and sugar with maple syrup. Nut-free option: substitute almond flour with oat or sunflower seed flour and omit sliced almonds.
