Ingredients

Streusel Topping

Wet

  • 1 medium ripe banana
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 3 tablespoons honey
  • 1 3/4 cups unsweetened oat milk

Dry

  • 1.5 cups quick-cooking oats
  • 1/4 cup oat flour
  • 1 teaspoon baking powder
  • pinch of salt
  • 1 pint blueberries ~2 cups

Instructions

  • First, preheat oven to 375ºF and line a 9x9-inch baking pan with parchment or spray with cooking spray.
  • Add the rolled oats, flour, brown sugar, butter, and vanilla extract to a mixing bowl. Use a spoon (or your hands work best) and cut the ingredients together until a crumble forms. This may take 4-5 minutes. Set streusel topping aside for later.

Tips & Notes

  • If you don’t have oat flour, you can substitute all-purpose flour or white whole wheat.
  • If you don’t have oat milk you can use almond milk.
  • You can substitute the blueberries for raspberries or blackberries.
  • If you want to use frozen blueberries, be sure to thaw them and strain any excess liquid from the blueberries.
