Ingredients List
Main Ingredients
2 cups old-fashioned rolled oats
2 scoops vanilla whey protein (about 62g)
1 tablespoon ground cinnamon
1/4 teaspoon salt
1 teaspoon baking powder
1 medium apple (about 160g, with skin), diced

1 cup non-fat milk (or any milk of your choice)
1 large egg
1/4 cup sugar-free maple syrup

Chopped fresh chives or parsley (for a savory twist)
Required Kitchen Tools
Having the right tools makes baking oatmeal a breeze. Here’s what I always use:
Mixing Bowls – A large bowl for dry ingredients and a medium bowl for wet ingredients keeps things organized.
Whisk – Essential for blending eggs, milk, and maple syrup smoothly.
Measuring Cups & Spoons – Accurate measurements help your baked oatmeal come out perfectly every time.
Baking Dish – I use an 8x8-inch square or similar-size oven-safe dish for even baking.
Spatula – Great for folding in the apples and ensuring all ingredients are evenly mixed.
Oven Mitts & Cooling Rack – For safely removing the hot dish and letting it cool slightly before serving.
Preparation and Baking Instructions
Baking this high-protein apple oatmeal is easier than it sounds—I promise! Follow these steps, and you’ll have a warm, comforting breakfast ready in under an hour.
Step 1: Preheat and Prep
First, preheat your oven to 350°F (175°C). While the oven warms up, lightly grease your 8x8-inch baking dish with a bit of butter or non-stick spray. This ensures your oatmeal doesn’t stick and makes cleanup a breeze.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine:
2 cups rolled oats
2 scoops vanilla whey protein
1 tablespoon cinnamon
1 teaspoon baking powder
1/4 teaspoon salt
Whisk these together until evenly blended. This helps distribute the protein powder and spices throughout the oatmeal.
Step 3: Combine Wet Ingredients
In a separate medium bowl, whisk together:
1 cup non-fat milk
1 cup unsweetened applesauce
1 large egg
1/4 cup sugar-free maple syrup
Once smooth, gently fold in the diced apple pieces. I like leaving the skin on for extra fiber and natural sweetness.
Step 4: Mix Wet and Dry Ingredients
Pour the wet mixture into the dry ingredients bowl. Using a spatula, gently fold everything together until all the oats are coated. Don’t overmix—the batter should be slightly thick but pourable.
Step 5: Bake the Oatmeal
Transfer the mixture into your prepared baking dish and smooth the top evenly. Bake in the preheated oven for 35–40 minutes, or until the top is golden and a toothpick inserted into the center comes out clean. The aroma of cinnamon and baked apple will fill your kitchen—it’s heavenly!
Step 6: Cool and Serve
Let the baked oatmeal cool for about 5–10 minutes. This helps it firm up slightly, making it easier to slice. I like to serve it warm, straight from the dish, and sometimes sprinkle with a few fresh apple slices or chopped chives for a subtle savory note.
Serving and Garnishing
I love serving this baked oatmeal warm, straight from the oven. It’s naturally sweet from the apples and maple syrup, so it pairs beautifully with a few extra touches:
Optional Garnish: Sprinkle with fresh chives or parsley for a subtle savory contrast, or add a handful of chopped nuts for crunch.
Toppings: A dollop of Greek yogurt, nut butter, or a drizzle of sugar-free maple syrup takes it to the next level.
Portioning: Slice into 6–8 squares for a satisfying breakfast or post-workout snack.
Storage Instructions
This baked oatmeal keeps well, making it perfect for meal prep:
Refrigeration: Store in an airtight container for up to 5 days. Reheat in the microwave for 30–60 seconds before serving.
Freezing: Slice into portions and wrap individually with parchment or foil, then place in a freezer-safe bag. Freeze for up to 2 months. Thaw overnight in the fridge or microwave for a quick breakfast.
Tips for the Best High Protein Apple Baked Oatmeal
Choose the Right Apple: I recommend firm, sweet-tart varieties like Honeycrisp or Fuji—they hold their shape and add natural sweetness.
Customize Your Protein: Vanilla whey works best, but chocolate or unflavored protein powders can also be used. Adjust cinnamon and sweetness if using flavored powders.
Moisture Balance: If your protein powder is particularly absorbent, add an extra 1–2 tablespoons of milk to keep the oatmeal moist.
Spice It Up: A pinch of nutmeg or ginger pairs beautifully with the apples and cinnamon.
Conclusion
This High Protein Healthy Apple Baked Oatmeal is my go-to breakfast for a nutritious, filling start to the day. It’s simple, flavorful, and packed with protein, fiber, and natural sweetness. Whether you’re meal prepping for the week, need a post-workout boost, or just want a cozy breakfast, this recipe delivers every time.
The best part? It’s versatile—you can tweak the fruit, protein, or spices to suit your taste, making it a staple in your healthy baking repertoire. Give it a try, and I promise it will become a favorite in your household too!
