Apple Maple Baked Oatmeal is pure breakfast comfort food. It’s delicious, easy to make and the leftovers are great for snacking.

Baked oatmeal is one of my favorite winter breakfasts. It’s mixed by hand in one bowl and you can prep the ingredients the night before.

I don’t like my breakfast to taste like dessert, so I use just enough maple syrup for a lightly sweet taste. An apple adds a little more sweetness and some moisture.

If you like your oatmeal sweeter you can add up to a 1/2 cup of white or brown sugar to the recipe.

Apple Maple Baked Oatmeal is delicious breakfast comfort food. It's easy to make and the leftovers make a great snack.

Ingredients

3 cups (10 oz, 280g) old-fashioned rolled oats
2 teaspoons baking powder
1 teaspoon ground cinnamon
1/2 teaspoon table salt
1/4 teaspoon nutmeg
1 1/2 cups (12 oz, 360ml) whole milk
1/2 cup (4 oz, 112g) unsalted butter, melted
1/2 cup (4 oz, 120ml) real maple syrup
2 large eggs
1 teaspoon vanilla extract
1 large apple, peeled and diced to 1/4"
1/2 cup walnuts, chopped fine
2 tablespoons granulated sugar for topping

Instructions

Preheat the oven to 350°F. Butter a 9" square pan.
In a large bowl, combine the oats with the baking powder, cinnamon, salt and nutmeg.
In a large measuring cup, whisk together the milk, melted butter, maple syrup and eggs.
Stir the liquid into the oat mixture until combined. Fold in the chopped apples and walnuts. Pour the batter into the prepared pan and smooth to an even layer. Sprinkle with granulated sugar.
Bake until the center springs back when lightly pressed or a toothpick inserted into the center comes out clean, 30-35 minutes. Optionally, you can turn on the broiler for a minute or two after the oatmeal is done baking. The broiler will caramelize the sugar for an extra crunchy topping.
Cool 10 minutes before slicing.
