Prep time

15 min.

Cook time

45 min.

  • 1 cup walnuts, divided
  • 2 cups old-fashioned rolled oats
  • 1 tsp baking powder
  • 1 tsp cinnamon plus extra for garnish
  • ¼ tsp kosher salt
  • 1 ¼ cups milk, any type (I used 2%)
  • ½ cup plain low fat Greek yogurt
  • 1 large egg
  • 1/3 cup maple syrup
  • 2 Tbsp melted coconut oil or unsalted butter
  • 1 tsp vanilla extract
  • 1 ½ cups blueberries, divided use
  • 1 ½ cups finely chopped, peeled apple, divided use

Preheat oven to 325 degrees Fahrenheit.

Spray an 8x8-inch baking dish with cooking spray. Finely chop ½ cup walnuts and place them in a bowl along with the oats, baking powder, cinnamon, and salt.

Whisk the milk, yogurt, egg, maple syrup, coconut oil, and vanilla together in another bowl.

Arrange 1 cup blueberries and 1 cup chopped apple in the bottom of the prepared baking dish. Scatter the oat mixture evenly on top. Pour in the milk mixture and press to submerge all of the dry ingredients in the liquid. Roughly chop the remaining ½ cup walnuts and scatter them on top along with the remaining ½ cup blueberries and ½ cup apple. Sprinkle with cinnamon.

Bake 40-45 minutes, until the top is golden and the oats are set. Serve warm or at room temperature.
