Ingredients
  

Main
  • 1 cup all purpose flour 120g
  • 1/2 cup cold unsalted butter 115g, cut into small cubes
  • 1/2 cup light brown sugar 100g, packed
  • 1/4 cup granulated sugar 50g
  • 1/4 teaspoon fine sea salt
  • 1/2 cup old fashioned rolled oats optional, for extra texture

Equipment

  • Large mixing bowl
  • Measuring cups and spoons
  • Pastry cutter or your fingertips
  • Fork for mixing
  • Baking dish for your chosen filling
  • Wire cooling rack

Method
 

  1. Cut cold butter into small half inch cubes and return them to the refrigerator for at least 10 minutes to ensure they stay cold.
  2. Add the flour, brown sugar, granulated sugar, and salt to a large mixing bowl. Whisk everything together until evenly distributed, breaking up any brown sugar clumps with your fingers.
  3. Scatter the chilled butter cubes over the flour mixture. Toss them lightly to coat each piece with flour, which prevents them from sticking together.
  4. Using your fingertips or a pastry cutter, work the butter into the flour by pressing and rubbing the mixture together until you have a shaggy texture with pieces ranging from pea sized to almond sized.
  5. If using oats, fold them in gently with a fork until just combined. Avoid overworking to preserve the irregular clumps.
  6. Squeeze handfuls of the mixture gently to form loose clusters, then break them apart over your filling to create chunky, craggy pieces.
  7. Scatter the crumble topping evenly over your prepared fruit or filling, leaving some gaps for steam to escape. Pile it slightly higher in the center.
  8. Bake at 375F (190C) for 30 to 40 minutes until the topping turns deep golden brown and the filling bubbles at the edges.
  9. Let the crumble rest for at least 10 minutes after baking so the filling can set properly before serving.

Notes

For extra crispy clusters, place the formed crumble topping on a baking sheet and freeze for 15 minutes before adding it to your filling. Unbaked crumble topping keeps in the refrigerator for up to 5 days or freezes for up to 3 months. Use directly from frozen, adding 5 to 10 minutes to baking time.
