This Banana Peanut Butter Baked Oatmeal is a delicious, healthy make-ahead breakfast . It's perfect for serving to a crowd or simply cutting into squares and enjoying as an on-the-go breakfast throughout the week.
Preheat oven to 350 degrees F. Lightly grease a 9x11 or 8x8 baking dish and set aside.
Attach the whisk attachment to a stand mixer. To the stand mixer bowl, add the bananas, oat milk, and eggs and whisk on low for 1 minute. Add the maple syrup, peanut butter and vanilla and whisk for another minute, until well combined.
In a mini blender, pulse 3/4 cup of the oats for 4-5 seconds, until they resemble coarse sand. Add the pulsed oats, remaining 3/4 cup rolled oats, baking powder, cinnamon and salt to the wet ingredients in the stand mixture. Whisk for 1 minute, until well combined.
Add the batter to the greased baking dish and bake for 35-40 minutes, until lightly golden on the edges, and a toothpick inserted into the center comes out clean. Allow to cool in the baking dish on a wire rack for 30 minutes. Then slice into squares and store in an airtight container.
*If your peanut butter doesn't contain salt, add 1/8 teaspoon salt with the dry ingredients.
