Ingredients Method Notes

Ingredients
  

For the Oat Base:
  • 2 cups old fashioned rolled oats
  • 2 cups unsweetened almond milk or milk of choice
  • 1/3 cup pure maple syrup or other preferred sweetener
  • 2 teaspoons ground cinnamon
  • 1 large egg beaten
  • 1 teaspoon baking powder
  • 1 1/2 cups fresh or frozen blueberries if using frozen, thaw and blot dry
For the Streusel Topping:
  • 1 cup old fashioned rolled oats
  • 1/2 cup all-purpose flour can substitute oat flour or almond meal
  • 1/2 cup brown sugar or coconut sugar
  • 1/4 teaspoon salt
  • 1/2 cup melted coconut oil or butter

Method
 

  1. 1. Prepare the Oats (Overnight):In a large bowl, combine oats, almond milk, maple syrup, and cinnamon. Stir well.Cover and refrigerate overnight to let the oats absorb the liquid and soften.
  2. 2. Assemble the Base (Next Morning):Preheat oven to 375°F (190°C). Grease an 8×8-inch baking dish.Add the beaten egg and baking powder to the soaked oats and mix to combine.Gently fold in the blueberries. Pour the mixture into the prepared baking dish and spread evenly.
  3. 3. Make the Streusel Topping:In a medium bowl, stir together rolled oats, flour, brown sugar, and salt.Add melted coconut oil (or butter) and mix until crumbly.Sprinkle the streusel topping evenly over the oat mixture.
  4. 4. Bake and Cool:Bake for 30–40 minutes, or until the oatmeal is set and the top is golden brown.If the streusel starts to brown too quickly, loosely cover with foil during the last 10 minutes.Let cool for 10–15 minutes before serving.

Notes

  • You can prepare the streusel the night before and store it separately in the fridge.
  • Serve warm as-is or with a splash of milk, a dollop of yogurt, or extra maple syrup.
  • Easily customizable—try it with raspberries, blackberries, or chopped apples.
  • Leftovers can be stored in the fridge for up to 5 days and reheated in the microwave.
