Ingredients

Old-Fashioned Gluten-Free Oats: Old fashioned oats give this baked oatmeal a chewy, firm texture perfect for cutting into squares.
Diced Apples: Apples give the oatmeal extra texture and tons of apple flavor.
Cinnamon: You can't have apple cinnamon anything without cinnamon!
Vanilla: I prefer Singing Dog Vanilla for its deep, rich flavor and quality.
Maple Syrup: Maple syrup sweetens the oatmeal without refined sugar.

See the recipe card at the end of the post for a full list of ingredients and their exact quantities.

Flavor Substitutions and Variations

Sweetener: Honey, agave, or monk fruit would also work for this recipe. If you aren't concerned with keeping things super healthy, you can also use brown sugar.
Apples: Try Granny Smith apples for a tarter apple cinnamon flavor. For a sweeter flavor, try Honey Crisp, Braeburn, or Cortland apples.
Add Nuts: Chopped pecans, walnuts, or almonds are a great addition for more flavor and texture.

How to Make Baked Apple Cinnamon Oats

1: Preheat the oven to 350 degrees and line an 8x8 baking pan with parchment paper.

2: Lightly beat the egg in a small bowl.

3: Combine the eggs, oats, and all remaining ingredients except the apples in a large bowl, mixing well with a rubber spatula. Add the diced apples and mix again. The mixture will be slightly wet.

4: Pour the oat mixture into the prepared pan and decorate with finely sliced apples. Bake for 30 to 35 minutes until the top is golden brown and the mixture is no longer wet.

5: Cool for a few minutes, slice, and enjoy!

Tips for the Best Apple Cinnamon Baked Oats

Make your parchment paper long enough to leave overhang so you can easily remove the baked oats when they're done.
It's important to mix everything with a spatula to achieve the best texture.
Always mix the apples in last. This ensures that all the other ingredients can properly mix without adhering to the apple chunks.
Your oat mixture will look wet before baking. That's good! If it doesn't look wet, it's too dry.
Let your baked oats cool for a few minutes so they can fully set. This allows them to hold their shape when sliced.

Storage

Refrigerate these baked apple cinnamon oats for up to 5 days in an air-tight container. For longer storage, wrap slices individually in plastic wrap and freeze for up to 2 months in an air-tight, freezer-safe container. Defrost overnight in the refrigerator before reheating.

What to Serve with Baked Apple Cinnamon Oats
