How to make baked oatmeal:
Like all of my baked oat recipes, preparation is a cinch and can be broken down into 4 simple steps.
- stirring together the dry ingredients (oats, nuts, baking powder, salt, cinnamon)
- whisking together the wet ingredients (milk, eggs, juice, syrup, vanilla)
- combining the wet and dry ingredients
- pouring the batter into a prepared pan and bake!
I also add the zest to the dry ingredients because I find it is much easier to distribute. If you add it to the wet ingredients, it tends to stay in one big clump.
Preheat the oven to 375 degrees.
While the oven is heating, prepare the batter. Once the batter is ready, the oven should be ready to go.
Peel and grate the apple with a course grater or box grater. I always use a Granny Smith apple for this recipe because I love the tartness, and they are available year round. But feel free to use whatever variety of apple you prefer.
There are 2 different ways to bake the oats:
- In a 9 x 9 inch baking dish that has been sprayed with cooking spray. This is my preferred method if intended to be eaten right away. I just plop it in the middle of the table with a big spoon and everyone takes a scoop.
- In a muffin pan that has been sprayed with cooking spray. This method is great for meal prepping. Once the oat cups have cooled, place them in a gallon sized ziplock bag and freeze until needed.
If baking in a 9 x 9 inch pan, bake for 60 minutes.
If baking in a muffin pan, bake for 30 minutes.
Allow the baked oats to cool for a few minutes to set.
Enjoy this warm, hearty breakfast on the go or packed in lunch boxes, or as an easy go-to weekend brunch with fresh fruit and a drizzle of warm maple syrup!

Apple Cinnamon Baked Oats
Ingredients
- 2 cups oats old fashioned
- 1 cup walnuts chopped
- 1 tsp baking powder
- 1/4 tsp kosher salt
- 1 tbsp cinnamon
- 1 orange zested
- 1 large apple (preferably Granny Smith) peeled and grated
- 2 eggs
- 1 tsp vanilla
- 1 cups unsweetened almond milk (or milk of your choice)
- 1 cup apple juice (no sugar added)
- 1/4 cup maple syrup
Instructions
- Preheat the oven to 375 degrees. Combine the oats, nuts, cinnamon, salt, baking powder and orange zest in a large bowl. In a separate bowl, whisk together the milk, eggs, juice, vanilla and maple. Pour the wet ingredients into the bowl with the dry ingredients.Add the grated apple and stir to combine. Pour the batter into a 9 x 9 inch baking dish that is sprayed with cooking spray, or divide the batter between 15-16 muffin cups that have been sprayed with cooking spray. If baking in the square dish: bake for 60 minutes, or until the center is cooked through. If the edges become too dark, lay a sheet of foil over the pan until it is fully cooked. Allow to cool for around 15 minutes to set before cutting. If baking in a muffin pan: bake for 30 minutes, then allow to cool for about 10 minutes. Run a butter knife or small offset spatula around the edge of the cups in case any of the batter has stuck to the walls before lifting them out.
