Ingredients:

  • 1 cup (125g) All-purpose flour
  • ½ cup (45g) Old-fashioned rolled oats
  • ½ cup (100g) Light brown sugar, packed
  • 1 tsp (2g) Ground cinnamon
  • ¼ tsp (1.5g) Fine sea salt
  • ½ cup (113g) Unsalted butter, cold and cubed

Instructions:

  1. Combine the flour, rolled oats, brown sugar, cinnamon, and salt in a large bowl. Whisk vigorously to break up any brown sugar clumps.
  2. Add the chilled, cubed butter to the flour mixture. Use a pastry cutter or two forks to work the butter into the flour until the mixture resembles coarse crumbs with some pea-sized chunks of butter still visible.
  3. Using your fingertips, gently pinch the mixture together and squeeze it into small, irregular clusters to create the crumble effect.
  4. Evenly sprinkle the crumble topping over prepared peach filling. Bake at 375°F (190°C) for 35-40 minutes until the topping is deep golden brown and peach juices are bubbling.
