Equipment

  • 9x9-inch baking dish
  • Mixing Bowls
  • Whisk

Ingredients
  

Dry Ingredients

  • 3 cups old-fashioned rolled oats not quick oats or steel-cut
  • 2 tsp baking powder
  • 1 1/2 tsp ground cinnamon
  • 1/2 tsp salt
  • 1/4 tsp nutmeg

Wet Ingredients

  • 2 large eggs
  • 2 cups milk dairy or plant-based
  • 1/4 cup maple syrup or honey
  • 2 tbsp melted coconut oil or butter
  • 2 tsp vanilla extract

Mix-ins

  • 2 cups mixed berries fresh or frozen
  • 1/2 cup chopped nuts walnuts or pecans work beautifully

Instructions
 

  • Preheat your oven to 350°F (175°C). Lightly grease a 9×9-inch baking dish with cooking spray or a thin layer of coconut oil.
  • In a large bowl, whisk together the rolled oats, baking powder, cinnamon, salt, and nutmeg until evenly distributed.
  • In a separate bowl, whisk the eggs until slightly frothy (about 30 seconds), then add milk, maple syrup, melted coconut oil, and vanilla extract. Whisk until thoroughly combined.
  • Pour the wet ingredients into the dry ingredients and stir until just combined. Avoid over-mixing.
  • Gently fold in 1½ cups of the berries and most of the nuts, reserving some for topping.
  • Pour the mixture into your prepared baking dish. Scatter the remaining berries and nuts on top.
  • Bake for 35-40 minutes, until the top is golden brown and the center is set but still slightly moist. The oatmeal should spring back slightly when gently pressed in the center.
  • Allow the baked oatmeal to rest for 5-10 minutes before serving.
