Ingredients

  • 40 g flour (1/4 cup)
  • 20 g old-fashioned rolled oats (1/4 cup)
  • 2 g ground cinnamon (1 teaspoon)
  • 1 g kosher salt (1/4 teaspoon)
  • 30 g light brown sugar (2 tablespoons)
  • 25 g butter, melted (2 tablespoons)
  • 0.5 g vanilla extract (1/8 teaspoon)

Method

  • In a bowl combine the flour, oats, cinnamon, salt, and brown sugar with a spoon or spatula until the dry ingredients are incorporated.
  • Pour in the melted butter and vanilla and toss the mixture until almond-size dark oat clusters form.
  • If youre making the pie the same day, the streusel can wait out on the counter.
  • If youre making the streusel in advance, transfer it to an airtight container and store in the fridge or freezer for up to 2 weeks.
