  • 3/4 cup (67 g) oats
  • 1/4 cup (50 g) light brown sugar, packed
  • 1/4 cup (30 g) all-purpose flour
  • 3 tablespoons (42.4 g) unsalted butter, cold and cut into cubes
  • 1/2 teaspoon (1.32 g) ground cinnamon
  • 1/4 teaspoon (2 g) salt


  • Preheat your oven to 375 degrees F. Line a baking sheet with parchment paper and set aside.
  • In a medium bowl, combine the oats, brown sugar, flour, butter, cinnamon and salt. Mix by hand with a wooden spoon until the mixture resembles clumps of sand. Spread the crumble over the parchment paper and bake for 8 to 10 minutes, stirring halfway through. The crumble should be golden brown. Let it cool completely and then crumble the mixture into smaller pieces, if needed.
