Ingredients for Cinnamon Apple Baked Oatmeal
Gather these items:
- 3 cups old fashioned oats
- 2 teaspoons cinnamon
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- 1 cup milk
- 1 cup unsweetened applesauce
- 2 large eggs
- 1/2 cup maple syrup (OR brown sugar)
- 2 teaspoons pure vanilla extract
- 2 cups chopped apple
- 1/2 cup chopped pecans
How to Make Cinnamon Apple Baked Oatmeal Step-by-Step
- Step 1: In a large mixing bowl, combine the oats, cinnamon, baking powder, and salt. Stir these dry ingredients well to evenly distribute the spices and leavening agent. Next, add the milk, unsweetened applesauce, eggs, maple syrup, and vanilla extract. Stir thoroughly, breaking up the eggs to create a uniform batter. Finally, fold in the chopped apples and pecans, ensuring they are evenly dispersed throughout the mixture.
- Step 2: Lightly grease a 9×13 inch baking dish with butter or non-stick spray to prevent sticking. Pour the oat mixture into the prepared dish and spread it out evenly.
- Step 3: Cover the dish with plastic wrap or a clean towel and place it in the refrigerator overnight. This resting time allows the oats to absorb the liquids fully, enhancing the texture and flavor of the baked oatmeal.
- Step 4: The following morning, preheat your oven to 350°F (175°C). Bake the oatmeal for 35 to 40 minutes, or until it is set in the center and the top has turned a beautiful golden brown. Once baked, transfer the casserole dish to a cooling rack and let it rest for 5 to 10 minutes before slicing. This helps the oatmeal firm up for clean, neat serving pieces.
