Ingredients
  

Main
  • 1 cup 125g all-purpose flour
  • 1/2 cup 100g granulated sugar
  • 1/4 cup 50g brown sugar, packed
  • 1/2 cup 115g unsalted butter, cold and cut into small cubes
  • 1/2 cup 45g old-fashioned rolled oats
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/4 teaspoon ground nutmeg optional

Equipment

  • Large mixing bowl
  • Pastry cutter or fork
  • Measuring cups and spoons
  • Baking dish
  • Parchment paper or aluminum foil

Method
 

  1. Cut your cold butter into small cubes, about half-inch pieces, and return them to the fridge for a few minutes if they start to soften.
  2. Whisk together the flour, both sugars, oats, cinnamon, salt, and nutmeg in a large bowl until evenly distributed.
  3. Add the cold butter cubes to your dry mixture and use a pastry cutter, fork, or your fingertips to work the butter into the flour until the mixture resembles coarse crumbs with some pea-sized pieces remaining.
  4. Squeeze a small handful of the mixture in your palm to check texture. It should clump together when pressed but fall apart into chunks when released. If it stays powdery, work in another tablespoon of cold butter.
  5. Arrange whatever you're topping (fruit, filling, etc.) in your baking dish, making sure it's spread evenly. If using raw fruit, toss it with a tablespoon or two of flour or cornstarch to prevent a soggy bottom.
  6. Sprinkle the crumble mixture evenly over your base in an even layer, covering it completely but without pressing it down.
  7. Bake at 350°F (175°C) for 25-35 minutes, or until the topping turns deep golden brown and you can see the filling bubbling around the edges.
  8. Let your baked creation rest for at least 10-15 minutes before serving so the filling can set slightly and the topping crisps up more.

Notes

Make a double or triple batch and freeze the extra in zip-top bags for up to 3 months. You can sprinkle it directly from frozen onto any fruit filling without thawing. Keep everything cold, especially your butter, which should come straight from the fridge. Don't overmix the butter into the flour or you'll develop gluten and end up with a tough texture. If topping browns too quickly, tent the dish loosely with aluminum foil and continue baking.
