Equipment

  • Oven

Ingredients

Fruit Filling

  • 4 Granny Smith apples peeled, cored, and thinly sliced; approx. 600g
  • 3 large rhubarb stalks sliced into ¾-inch chunks; approx. 360g
  • ¼ cup granulated sugar aka raw sugar; approx. 50g

Crumble Topping

  • cup old-fashioned rolled oats approx. 60g
  • ½ cup all-purpose flour approx. 60g
  • ½ cup packed brown sugar light or dark; approx. 107g
  • cup plant-based butter or vegan margarine; cold; approx. 75g
  • ¼ tsp salt approx. 1.5g

Instructions

  • Preheat the oven to 360°F. Lightly grease a medium baking dish (around 8x8 inches or similar).

Prepare the fruit filling:

  • Add the sliced apples, chopped rhubarb, and granulated sugar to the prepared baking dish. Toss to combine and spread into an even layer.

Make the crumble topping:

  • In a medium bowl, combine oats, flour, brown sugar, and salt. Add the cold plant-based butter and use your fingertips to rub it into the dry ingredients until the mixture resembles coarse crumbs.

Assemble & Bake:

  • Sprinkle the crumble topping evenly over the fruit mixture.
  • Bake for 40–45 minutes, or until the top is golden brown and the edges are bubbling.
  • Let the crumble sit for 5–10 minutes before serving. Serve warm with vegan ice cream or custard if desired.
