Prep Time

Total Time

Ingredients

  • 1 cup oats
  • 1 cup cashews*
  • 2 1/2 tbsp maple syrup (or to taste)
  • 1 tbsp butter or coconut oil, melted
  • Pinch of salt
  • 1/2 tsp cinnamon
  • 1 tbsp water (optional)
  • 1 tsp vanilla sugar
  • 10 oz / 280 g fresh strawberries, chopped (about 2 cups)

Instructions

  1. Place the oats and cashews in a small high-speed blender or nut grinder and process until they form a coarse flour. Pulse carefully so you don’t turn the mixture into a paste.
  2. Transfer the oat-nut flour to a bowl and stir in the melted coconut oil or butter, cinnamon and maple syrup. The mixture should be crumbly but able to hold small clumps when pressed between your fingers.
  3. Add a pinch of salt and, if the mixture is too dry, stir in up to 1 tablespoon water to help it come together. Taste the crumbs and add a little more maple syrup if you prefer it sweeter.
  4. Preheat the oven to 350°F / 180°C. Lightly oil a small baking pan so the fruit juices won’t stick as it bakes.
  5. Place the washed, hulled and chopped strawberries into the prepared pan. Sprinkle the vanilla sugar (or a little vanilla extract) over the berries and gently shake or toss the pan so the fruit is evenly coated.
  6. Use your hands to break the oat-nut mixture into uneven crumble pieces and scatter them over the strawberries until the fruit is mostly covered.
  7. Bake for 20–25 minutes, or until the topping is golden and the strawberry juices are bubbling around the edges. If you prefer a crunchier top, bake a few minutes longer while watching closely.
  8. Remove from the oven and let the crumble cool for a few minutes so it sets slightly. Serve warm with Greek yogurt, milk, or a scoop of vanilla ice cream for a richer treat.
  9. Store leftovers in an airtight container in the refrigerator for 3–4 days. Reheat gently before serving if you like it warm.

Notes

*You can swap cashews for other nuts such as almonds or hazelnuts. If you use softer nuts like pecans or walnuts, you may need slightly less butter or coconut oil because they pack more natural oil.

For a gluten-free result, ensure your oats are certified gluten-free. Adjust the sweetness to your taste—fresh ripe strawberries can make the crumble sweeter, so taste before adding extra maple syrup.

This crumble keeps well and makes an excellent make-ahead breakfast: portion it into containers and reheat for a quick morning treat.
