How to Make No-Flour, No-Sugar Oatmeal Breakfast Bake Recipe
Step 1: Preheat and Prepare
Start by heating your oven to 350°F (175°C). Take a moment to lightly grease an 8×8-inch baking dish with nonstick spray or coconut oil—this helps your finished bake lift out beautifully, so no slice goes to waste!
Step 2: Mix the Dry Ingredients
In a large mixing bowl, combine the rolled oats, baking powder, ground cinnamon, and salt. Give it a good stir so the leavening and spices are evenly distributed—this step ensures every bite is flavorful and tender.
Step 3: Whisk the Wet Ingredients
In a separate bowl, mash your ripe bananas until fairly smooth, then whisk in the eggs, milk, vanilla extract, and maple syrup or honey (if you’re using it). The banana not only sweetens the bake but also keeps it moist and tender.
Step 4: Combine Wet and Dry
Pour the wet mixture into the bowl of dry ingredients. Stir gently until everything is just combined—don’t over-mix. If you’re adding nuts, seeds, berries, or apples, fold them in now for extra texture and flavor.
Step 5: Bake to Perfection
Spread the mixture evenly in your prepared baking dish, smoothing the top with a spatula. Slide it into the oven and bake for 30 to 35 minutes, or until the center is set and the top turns beautifully golden. Let the bake cool for 5 to 10 minutes—this helps it firm up for perfect slices.

Garnishes
Top each warm slice with a dollop of creamy yogurt, a drizzle of nut butter, or a scatter of fresh fruit. A sprinkle of cinnamon or a handful of toasted nuts can make it even more inviting—let your toppings reflect the season or your mood!
Side Dishes

Creative Ways to Present
Try cutting the bake into fun shapes with cookie cutters for a playful breakfast, or layer cubes in parfait glasses with yogurt and fruit for a brunch-worthy presentation. You can even wrap individual slices for a grab-and-go meal that’s both pretty and practical.

FAQs
Can I make the No-Flour, No-Sugar Oatmeal Breakfast Bake Recipe vegan?
Absolutely! Swap the eggs for flax eggs and use your favorite plant-based milk. Maple syrup is already vegan, and the bake will still be delicious and sliceable.

Chopped walnuts, pecans, sunflower seeds, fresh or frozen berries, and small diced apples are all fantastic. Mix and match to suit your cravings or use whatever you have on hand!

Yes! Simply bake it in a 9×13-inch pan, and keep an eye on the baking time. It might need a few extra minutes but will turn out just as delicious and perfect for a crowd.
