Essential Ingredients for Your Apple Cinnamon Walnut Baked Oatmeal
Crafting this protein and fiber-packed Apple Cinnamon Walnut Baked Oatmeal requires a selection of simple, wholesome ingredients that come together to create a truly spectacular breakfast. Each component plays a crucial role in delivering flavor, texture, and nutritional value. Remember, this recipe yields approximately **22 Grams of Protein & 13 Grams of Fiber** per serving!
**Wet Ingredients:**
- 2 cups unsweetened almond milk: Or any milk of your choice. Almond milk provides a light, dairy-free base, but cow’s milk, soy milk, or oat milk can also be used.
- ½ cup Vanilla Orgain protein powder (or 4 scoops): This adds a significant protein boost (Orgain often contains 42 grams per ½ cup). You can use any vanilla-flavored protein powder you prefer, or omit it entirely if you’re not looking for extra protein (just note that you may need to increase the sweetener if omitting).
- 2 tablespoons flax seeds: A fantastic source of omega-3 fatty acids and dietary fiber, contributing to a healthy digestive system and a slightly nutty flavor.
- 2 tablespoons chia seeds: Another superfood, chia seeds absorb liquid to create a gel-like texture, adding thickness, fiber, and omega-3s.
- 3 teaspoons cinnamon: The star spice! Cinnamon brings warmth, sweetness, and a host of antioxidant benefits.
- 2 tablespoons agave or maple syrup: Natural sweeteners that complement the apple and cinnamon flavors. If you’re not using protein powder, consider adding 2 more tablespoons for desired sweetness.
- ½ teaspoon salt: Essential for balancing the flavors and enhancing the sweetness of the other ingredients.
- 1 teaspoon vanilla extract: A crucial flavor enhancer that adds depth and aroma.
- 1 teaspoon baking powder: Helps the oatmeal achieve a light, fluffy texture, preventing it from becoming too dense.
- ½ cup unsweetened applesauce: Provides natural sweetness and moisture. A mashed medium-sized banana can be substituted for a different flavor profile and added creaminess.
- ¼ cup Jif No Sugar peanut butter: Or almond butter, cashew butter, or Sun butter. Nut butter adds healthy fats, protein, and a rich, satisfying flavor.
**Dry Ingredients & Add-Ins:**
- 2 cups Kodiak® Protein Classic Rolled Oats: These oats are fortified with protein (40 grams per 2 cups), making them an excellent choice for a protein-rich breakfast. Any brand of old-fashioned rolled oats will work, and gluten-free rolled oats can be used for a gluten-free version of this bake.
- 1 ½ cups chopped apples: Varieties like Granny Smith or Honeycrisp work wonderfully, offering a balance of tartness and sweetness. Reserve some to sprinkle on top before baking for an extra visual and textural appeal.
- ½ cup chopped walnuts: These add a delightful crunch, healthy fats, and a distinct nutty flavor that pairs perfectly with apples and cinnamon.

Instructions: How to Make the Most Delicious Apple Cinnamon Walnut Baked Oatmeal Ever
Get ready to create a breakfast masterpiece that’s as simple to make as it is incredibly delicious and nutritious. Follow these straightforward steps to prepare your Apple Cinnamon Walnut Baked Oatmeal – trust us, the wholesome flavor and incredible health benefits are truly worth it!
- **Prepare Your Baking Dish:** Begin by preheating your oven to 375 degrees Fahrenheit (190°C). Lightly spray a 9-inch baking dish with a non-stick cooking spray to ensure your baked oatmeal doesn’t stick and comes out perfectly.
- **Combine Wet Ingredients:** In a large mixing bowl, combine the unsweetened milk of your choice, vanilla protein powder, flax seeds, chia seeds, cinnamon, agave or maple syrup, salt, vanilla extract, and baking powder. Whisk vigorously until all these wet ingredients are thoroughly blended and smooth.
- **Integrate Applesauce/Banana and Nut Butter:** In a separate small bowl, mash your banana (if using as a substitute) and mix it with the unsweetened applesauce or peanut butter until creamy. Add this mixture to your large bowl of wet ingredients and whisk again until everything is perfectly combined and homogenous.
- **Fold in Oats:** Gently add the old-fashioned rolled oats to the wet mixture. Using a rubber spatula or a wooden spoon, mix until the oats are just incorporated. Be careful not to overmix, as this can lead to a tougher texture.
- **Add Apples and Walnuts (First Batch):** Take about two-thirds of your chopped apples and walnuts. Fold these into the oat mixture. This ensures a good distribution of fruit and nuts throughout the baked oatmeal.
- **Transfer to Pan and Top:** Pour the entire oat mixture evenly into your prepared baking dish. Once spread, sprinkle the remaining one-third of chopped apples and walnuts over the top. This creates a beautiful, caramelized crust and ensures you get delicious fruit and nut in every bite.
- **Bake to Perfection:** Carefully place the baking dish into your preheated oven. Bake for approximately 45 minutes, or until the oatmeal is set in the center and the top is golden brown and slightly firm to the touch. A toothpick inserted into the center should come out mostly clean.
- **Cool, Slice, and Serve:** Once baked, remove the pan from the oven and allow the Apple Cinnamon Walnut Baked Oatmeal to cool slightly before slicing. Serve warm, perhaps with a delicate drizzle of maple syrup or agave for extra sweetness, a generous dollop of Greek yogurt for an added protein boost, or a splash of milk – customize it however you like! I personally love to warm an individual slice in the microwave for 15-30 seconds for that ultimate cozy, comforting breakfast experience. Enjoy every scrumptious bite!


Storing Your Healthy Apple Cinnamon Walnut Baked Oatmeal for Freshness
One of the many benefits of this Apple Cinnamon Walnut Baked Oatmeal is how perfectly it stores, making it an ideal option for meal prepping and enjoying healthy breakfasts throughout the week. Proper storage ensures your baked oatmeal remains fresh and delicious.
- **Refrigerator Storage:** Once your baked oatmeal has cooled completely, slice it into individual portions. Store these slices in an airtight container in the refrigerator for up to 4-5 days. When you’re ready to enjoy a cozy breakfast, simply warm a slice in the microwave for about 30 seconds, or until heated through. It’s just as delicious on day five as it is fresh from the oven!
- **Freezer Storage:** For longer-term storage, this apple breakfast bake freezes beautifully. Allow the entire dish to cool completely before cutting it into individual slices. Place these slices in an airtight, freezer-safe container, separating layers with parchment paper to prevent sticking. Your baked oatmeal can be stored in the freezer for up to 3 months. To reheat, you can thaw a slice in the refrigerator overnight and then warm it in the microwave, or heat directly from frozen at a lower power setting in the microwave until thoroughly warm.
Creative Variations: New Ideas for Your Apple Cinnamon Walnut Baked Oatmeal
The beauty of this Apple Cinnamon Walnut Baked Oatmeal recipe lies in its incredible adaptability. While the original recipe is a flavor sensation, don’t hesitate to get creative and customize it to your heart’s desire. Here are some inspiring ideas to transform your baked oatmeal into new and exciting culinary experiences:
- **Berry Burst Oatmeal:** Elevate your fruit game by adding 1 cup of your favorite berries directly into the mixture. Strawberries, blueberries, raspberries, or mixed berries all work wonderfully. For an extra touch of freshness and visual appeal, sprinkle some additional fruit on top before baking. This adds a vibrant tang and boosts antioxidant content.
- **Decadent Chocolate Oatmeal:** For the chocolate lovers, this variation is a dream! Simply swap the vanilla protein powder for a chocolate-flavored protein powder. To enhance the chocolate experience, stir in some mini chocolate chips (dairy-free if maintaining vegan status) into the batter before baking. The warmth of the baked oatmeal will slightly melt them, creating pockets of gooey chocolate bliss.
- **Nutty Raisin & Spiced Oatmeal:** If you’re a fan of classic oatmeal raisin cookies, you’ll love this twist. Add 1 cup of plump raisins along with some extra walnuts or even pecans to your oatmeal mixture. After baking, consider a luxurious topping: a delicate drizzle of melted white chocolate (vegan white chocolate chips are available) or a homemade glaze. To make a simple glaze, whisk together 1/2 cup of organic powdered sugar with a tablespoon or more of dairy-free milk until smooth and pourable.
- **Super Seed & Nut Medley:** Beyond flaxseed and chia seeds, there are countless ways to boost the nutritional profile and texture of your baked oatmeal. Experiment with adding hemp seeds for extra protein and healthy fats. Incorporate different nut butters like almond butter, cashew butter, or even sunflower seed butter for unique flavors. For a varied crunch, try pistachios, almonds, or even pumpkin seeds. For a touch of fruity elegance, swirl in some sliced fresh strawberries or raspberries during the last few minutes of baking, or serve them on top for a vibrant contrast. The possibilities truly are limitless when it comes to customizing your healthy baked oatmeal!

In conclusion, this Apple Cinnamon Walnut Baked Oatmeal is far more than just a delightful breakfast dish – it’s a versatile, incredibly nutritious, and profoundly satisfying meal that can be enjoyed by anyone. It caters to a range of dietary preferences with its easily adaptable ingredients and offers a delicious texture and explosion of flavors that will brighten your morning.
Through its thoughtfully selected, simple ingredients and straightforward preparation, this apple baked oatmeal recipe harmoniously combines the natural sweetness of apples, the comforting warmth of cinnamon, and the wholesome crunch of walnuts. This combination not only creates an undeniably delicious flavor profile but also delivers a wide array of health benefits, from sustained energy and digestive support to heart-healthy fats and vital micronutrients. So, why hesitate? Give this recipe a try and experience the remarkable difference a truly nourishing and delicious breakfast can make.
