Baked Oatmeal with Apple, Banana, and Walnuts
Ingredients
1 cup oatmeal
1 glass of milk
1 apple, chopped
1 banana, sliced
3 eggs
Vanillin sweetener (to taste)
60g walnuts, chopped

Directions
Prepare the Oats:
In a large mixing bowl, combine 1 cup of oatmeal and 1 glass of milk.
Let the mixture sit for 10 minutes to allow the oats to absorb the milk.
Prepare the Fruits:
Chop the apple into small pieces.
Slice the banana.
Mix the Batter:
After the oats have soaked, add the chopped apple and sliced banana to the bowl.
Crack the 3 eggs into the mixture and add the vanillin sweetener to taste.
Mix everything well until fully combined.
Add the Nuts:
Stir in the chopped walnuts, ensuring they are evenly distributed throughout the mixture.
Bake:
Preheat your oven to 180°C (360°F).
Pour the mixture into a baking dish, spreading it out evenly.
Bake in the preheated oven for 40 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Cool and Serve:
Allow the baked oatmeal to cool completely before cutting it into squares or slices.
Serve as is, or with a dollop of yogurt or a drizzle of honey for extra flavor.
