Ingredients
For the base:
- 2 cups gluten-free rolled oats
- 1 teaspoon baking powder
- 1 ½ teaspoons ground cinnamon
- ½ teaspoon ground nutmeg
- ¼ teaspoon salt
- 1 ½ cups unsweetened almond milk (or any milk of your choice)
- 1 tablespoon ground flaxseed (or 1 egg for non-vegan)
- 1 teaspoon vanilla extract
- 1 large apple, diced
- ¼ cup unsweetened applesauce
Optional protein boost:
- 1 scoop vanilla whey protein powder (or a plant-based protein powder for vegan option)
For toppings:
- Sliced banana
- Fresh blueberries
- Diced apple
- Chopped nuts (like pecans or walnuts)
- Drizzle of almond butter or maple syrup
Instructions
Preheat your oven
Set it to 350°F (175°C) and grease an 8×8-inch baking dish with cooking spray or a bit of oil.
Mix the dry ingredients
In a large bowl, combine the oats, baking powder, cinnamon, nutmeg, and salt. Stir well to evenly distribute the spices.
Prepare the wet ingredients
In a separate bowl, whisk together the almond milk, ground flaxseed (or egg), vanilla extract, and applesauce. If you’re adding protein powder, mix it into this wet mixture to ensure it dissolves properly.
Combine the wet and dry ingredients
Pour the wet mixture into the bowl with the dry ingredients. Stir until fully combined. Gently fold in the diced apple.
Transfer to the baking dish
Spread the mixture evenly in the prepared baking dish, smoothing the top with a spatula.
Add your toppings
Arrange your desired toppings over the surface. For a fruity twist, scatter fresh blueberries or sliced bananas. If you love extra crunch, sprinkle chopped nuts on top.
Bake
Place the dish in the oven and bake for 35–40 minutes, or until the oatmeal is set and the top is lightly golden.
Cool and serve
Allow the oatmeal to cool for 5 minutes before slicing into squares or scooping out portions. Enjoy it warm, or let it cool completely and refrigerate for up to 5 days.
Tips for Success
- Meal prep perfection: Cut the baked oatmeal into individual servings and store them in airtight containers in the fridge. Reheat a slice in the microwave for 30–40 seconds for a quick and hearty breakfast.
- Vegan option: Swap the egg for ground flaxseed or chia seeds mixed with water (1 tablespoon of seeds + 3 tablespoons water, let sit for 5 minutes).
- Gluten-free oats: Make sure your rolled oats are certified gluten-free if you have gluten sensitivities.
- Protein boost: When adding protein powder, reduce the almond milk slightly to maintain the right consistency.
High-Protein Variations
- Peanut Butter Delight: Stir in 2 tablespoons of natural peanut butter to the wet mixture and top with banana slices and a drizzle of peanut butter.
- Berry Bliss: Add ½ cup of fresh or frozen mixed berries to the base before baking. Top with more berries after baking for a double dose of antioxidants.
- Apple Pie Protein: Use diced apple in the base, sprinkle with extra cinnamon, and serve with a dollop of Greek yogurt for added protein.
Serving Suggestions
Serve a slice of Apple Cinnamon Baked Oatmeal on its own for a simple, wholesome breakfast. For added flair, pair it with a dollop of almond butter or a drizzle of maple syrup. It also works as a snack or a healthy dessert option.
