How to Make It

Follow these simple steps to create your delicious baked oatmeal.

Preheat

Preheat your oven to 350°F (175°C) and lightly grease a 9-inch square dish with cooking spray or avocado oil.

Mix Wet Ingredients

In a large bowl, combine the mashed banana, peanut butter, maple syrup, milk, egg (or flaxseed mixture for vegan), and vanilla extract. Whisk until fully combined.

Add Dry Ingredients

Stir in the rolled oats, cinnamon, baking powder, salt, and ground flaxseed (if using). Mix until all ingredients are well incorporated. If your batter is too stiff, you may need to add a dash of milk.

Pour

Pour the mixture into the greased baking dish, spreading it evenly.

Bake

Bake for 35 to 45 minutes, until the top is golden brown and the center is set.

Serve

Allow the baked oatmeal to cool for 5 minutes before serving. Optionally, drizzle with extra peanut butter and garnish with banana slices.
