Ingredients

Scale

Wet Ingredients

  • 1 and 3/4 cups (420ml) milk (dairy or nondairy)
  • 2 large eggs
  • 1/2 cup (120ml) pure maple syrup
  • 1/4 cup (4 Tbsp; 56g) unsalted butter, melted and slightly cooled
  • 1/4 cup (60g) unsweetened applesauce or mashed banana
  • 1 teaspoon pure vanilla extract

Dry Ingredients

  • 3 cups (255g) old-fashioned whole rolled oats
  • 1 teaspoon baking powder
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt

Additional Ingredients

  • 1 and 1/2 cups (225g) fresh or frozen mixed berries (do not thaw)
  • Optional: 1/2 cup chopped walnuts or pecans for topping

Instructions

  1. Preheat and prepare pan: Adjust the oven rack to the lower third position and preheat the oven to 350°F (177°C). Spray a 9×9 inch square pan or an 11×7 inch rectangle pan (or any similar 3-quart capacity pan) with nonstick spray to prevent sticking.
  2. Mix ingredients: In one large bowl, whisk together the milk, eggs, pure maple syrup, melted butter, unsweetened applesauce or mashed banana, and vanilla extract until well combined. Add the rolled oats, baking powder, cinnamon, and salt, then mix thoroughly. Gently fold in the fresh or frozen mixed berries, reserving some if you’d like to top the oatmeal before baking.
  3. Assemble in pan: Pour the oatmeal mixture into the prepared baking pan, spreading it evenly. If desired, sprinkle chopped walnuts or pecans on top or gently mix them into the batter before baking.
  4. Bake: Place the pan in the oven and bake for about 35 minutes, or until the center is almost set for a moist, soft texture. For a firmer, drier baked oatmeal, bake until the center is fully set, which may require an additional 5–10 minutes.
  5. Cool and serve: Remove from the oven and allow the baked oatmeal to cool for 5 minutes before slicing or spooning it out. Serve warm, optionally topped with yogurt or your favorite toppings. Store leftovers in a tightly covered container in the refrigerator for up to 1 week.

Notes

  • If using a larger 9×13 inch pan, the oatmeal will bake thinner and faster; reduce baking time slightly and check for doneness earlier (around 25-30 minutes).
  • You can customize the sweetness by adjusting the amount of maple syrup or substitute with honey or agave syrup.
  • For a vegan version, use plant-based milk, replace eggs with 1/4 cup ground flaxseed mixed with 3/4 cup water (let sit 5 minutes), and ensure your butter substitute is vegan.
  • Do not thaw frozen berries before adding to the mixture to prevent excess moisture.
  • Leftovers can be reheated in the microwave or oven and make great meal prep breakfasts.
