How to Make Apple Cinnamon Baked Oatmeal
-
Preheat: Begin by preheating your oven to 325°F. Grease a 9×9-inch baking pan to prevent sticking.
-
Arrange Apples: Chop your apples and spread them evenly at the bottom of the greased pan. This layer will caramelize beautifully as it bakes.
-
Mix Dry Ingredients: In a medium bowl, combine the old fashioned rolled oats, brown sugar, baking powder, ground cinnamon, and salt. Mix well to distribute all the flavors.
-
Whisk Wet Ingredients: In a larger bowl, whisk together the milk, eggs, and vanilla extract until fully combined. This will help create a rich and moist texture.
-
Combine Mixtures: Gently fold the dry mixture into the wet ingredients. Add in the melted butter, raisins, and half of the chopped walnuts, stirring until everything is evenly coated.
-
Pour and Top: Pour the oatmeal mixture over the apples in the pan, spreading it out evenly. Sprinkle the remaining walnuts on top for added crunch.
-
Bake: Place the pan in the preheated oven and bake for 40-45 minutes, or until the top is golden brown and set. You’ll know it’s ready when the edges start to pull away from the pan.
Optional: Serve warm with a drizzle of maple syrup for an extra touch of sweetness.
