How to Make

Preparation:
Start by preheating your oven to 375°F (190°C) – the perfect temperature for baking up a comforting breakfast delight. In a medium-sized bowl, unite the dry ingredients: nutty oats, a touch of cinnamon for warmth, a generous helping of chopped walnuts for that satisfying crunch, and a dash of baking powder and a pinch of salt to bring it all together.

Mixing and Baking:
Next, in a separate bowl, gather your wet ingredients. Crack in an egg for that binding magic, melt a bit of butter for that rich depth, and add in the star of the show: a ripe and smashed banana, lending its natural sweetness and moistness. Pour in low-fat milk or plain almond milk, and a drop of vanilla extract to elevate the flavor. Mix these luscious wet ingredients into the dry mix, giving it a friendly stir for about a minute – just enough time for everything to harmonize.

Baking and Serving:
Now, it’s time to bake. Grease an 8×8 casserole dish, and pour in your batter. Slide it into the preheated oven, where it will bake for roughly 20 to 25 minutes. Keep an eye on it – when it’s lightly golden and set, that’s your cue. Once baked to perfection, allow it a brief cooling moment, around 5 minutes, before diving in. If you want firm oats, use a toothpick to test the center for doneness.

Consider topping your creation with extra slices of fruit – a touch of sweetness to complement the heartiness of the oatmeal.

Substitutions

Oats: If you’re looking to switch up the oats, consider using quinoa flakes, millet, or a mixture of different grains for a unique texture.

Nuts: Swap walnuts with almonds, pecans, or hazelnuts, or go nut-free by adding seeds like pumpkin or sunflower seeds.

Bananas: Instead of bananas, experiment with mashed berries, grated apples, or even pumpkin puree for a seasonal twist.

Milk: Opt for your favorite milk alternative, such as oat milk, coconut milk, or yogurt for added creaminess.
