Ingredients & Equipment You'll Need
- Old Fashioned Rolled Oats - (also called rolled oats) are soft, flaky, and perfect for baking. For gluten-free purposes, be sure to use certified gluten-free oats.
- Baking Powder - adds volume to the baked oatmeal mixture and helps it rise a bit.
- Salt - enhances the sweet and spiced flavors.
- Cinnamon - gives this oatmeal classic apple pie flavor. You can also add a dash of nutmeg or use apple pie spice instead.
- Vanilla Whey Protein Powder- I used Quest vanilla milkshake whey protein with great results. You can leave this out for regular baked oats. We like the protein boost and if you use a good-tasting and good-quality protein powder you won't even know it's in there. 😉 You can also swap the whey for collagen peptides.
- Vanilla - adds pleasant sweet and caramelized flavor.
- Unsweetened Almond Milk - (or your milk of choice) adds moisture to soften the rolled oats.
- Unsweetened Applesauce - adds moisture and apple flavor to these cake-like oats.
- Eggs - helps bind the oats together.
- Maple Syrup - sweetens the oatmeal perfectly without adding any refined sugar.
- Ground Golden Flaxseed- is a good source of antioxidants, fiber, and healthy fat.
- Chopped Walnuts - adds healthy fats and a nutty crunch to each bite. Chopped pecans are also great here.
- Baked Cinnamon Apples- you'll need fresh apples to whip up this quick microwave cinnamon apple recipe for your topping. I either make these the day before or while the oats are baking. They are so quick and easy! Use the leftovers to top Apple Cinnamon Protein Pancakes or waffles!
- Two 6 x 2" Baking Dishes- or baking ramekins of similar size.
How To Make Apple Pie Baked Oatmeal
To make this baked apple cinnamon oatmeal, follow these easy-to-follow instructions:
Step 1 Preheat oven and prep baking dish:
Preheat the oven to 350 degrees F. Spray two 6x2" baking dishes with cooking spray. Set aside.
Step 2 Blend ingredients: Add the milk, eggs, applesauce, maple syrup, oats, protein powder, vanilla, cinnamon, baking powder, and salt to the blender container and blend until just blended and smooth. For easy blending, add the wet ingredients before the dry ingredients.
Step 3 Bake:
Pour the oat mixture into the prepared baking dish and sprinkle with nuts and a little Purecane brown sugar substitute or coconut sugar, if desired.
Bake for 20-25 minutes (check for doneness at 20 minutes).
Here are a few of my favorite toppings for apple pie baked oats:
- Nut Butter- peanut butter, almond butter, and cashew butter are delicious drizzled on top of baked oats. I like to heat it in the microwave for 30-45 seconds and drizzle that warm goodness on top. Heaven.
- Chia seeds- add a nice fiber boost and crunch.
- Maple syrup- these oats are perfectly sweet with the addition of maple syrup in the batter, but you can also add a drizzle of maple syrup (regular or sugar-free) or a sprinkle of brown sugar on top.
- Greek yogurt- I love adding a scoop of plain Greek yogurt for an added protein boost. This helps me easily hit my 30 grams a meal goal.
- Ice cream- these apple pie oats have a cake-like texture and double as a delicious dessert topped with ice cream or whipped cream. Tastes like homemade apple pie, but is much healthier!
Variations and Substitutions
To make dairy-free baked apple pie oatmeal, use any type of non-dairy milk (almond, soy, coconut, cashew, oat, etc.) and use your favorite plant-based protein powder.
In place of cinnamon or in addition, you can use an apple pie spice mix.
Pour into smaller ramekins and make mini baked apple pie oatmeals, or double-up the recipe and bake in a casserole dish, just be sure to adjust the cooking time.
Storing & Freezing
Storing: You can store these baked oats at room temperature in a sealed container for up to 2 days or stored in a sealed container in the refrigerator for 5 to 6 days. However, the texture of these cake-like baked oats is best fresh from the oven.
Freezing: Wrap cooled and sliced baked oatmeal portions in a couple of layers of plastic wrap and freeze in a freezer-safe container for up to 6 months. Thaw in the fridge or reheat in the microwave straight from the freezer.
What's the best way to reheat baked oatmeal?
You can reheat baked oats in the microwave in 20-30 second increments until just warm or in a 300-degree F oven until heated through. Heating them too long will dry them out.
Can you make this protein-baked oatmeal batter in advance?
I recommend preparing the batter and baking right away so that the oat flour or ground oats don’t soak up too much of the liquid and affect the texture. You can always bake them ahead and reheat them the next day for meal prep.
Can you use steel cut oats in baked oatmeal?
No, I do not recommend using steel-cut oats for this recipe. Steel-cut oats have a coarse texture and require a longer cooking time. You need to use old-fashioned oats/rolled oats to achieve the proper cake-like texture for this baked oats recipe.
