• 2 teaspoons ground cinnamon

For the Protein Glaze:

Pro Tips

Balance Your Protein Sources: When selecting protein powder for your High Protein Cinnamon Roll Baked Oatmeal, choose one with a mild flavor profile that complements the cinnamon. Whey isolate works beautifully for a tender texture, while plant-based options like a vanilla pea/rice blend maintain the protein content for vegan variations. The combination of protein powder with Greek yogurt creates a balanced amino acid profile superior to using either source alone.

Perfect Texture Control: The key to avoiding dry, rubbery baked oatmeal lies in proper liquid ratios. If your protein powder is particularly absorbent, increase the milk by 2-3 tablespoons. For a more custard-like center, reduce baking time by 5 minutes and allow it to set while cooling. Conversely, for a firmer texture ideal for meal prep, bake until the edges turn golden brown and pull away slightly from the pan.

Cinnamon Swirl Technique: For the most dramatic and flavorful cinnamon swirl effect, drizzle the cinnamon mixture in a spiral pattern over the oatmeal base, then use a knife to create deep “figure 8” motions throughout the mixture. This distributes the cinnamon flavor while maintaining distinct swirls rather than fully incorporating the mixture, giving you that authentic cinnamon roll experience in every bite.

Instructions

Step 1: Prepare Your Baking Dish
Preheat your oven to 350°F (175°C). Lightly grease an 8×8-inch baking dish with cooking spray or coconut oil. This preparation ensures your High Protein Cinnamon Roll Baked Oatmeal releases easily after baking and develops those desirable crispy edges.

Step 2: Mix Dry Ingredients
In a large bowl, combine the rolled oats, protein powder, ground flaxseed, baking powder, and salt. Whisk thoroughly to eliminate any clumps, especially from the protein powder, which can sometimes create dry pockets if not properly incorporated.

Step 3: Combine Wet Ingredients
In a separate bowl, whisk together the eggs, Greek yogurt, almond milk, maple syrup, melted coconut oil, and vanilla extract until smooth and well combined. The mixture should have a uniform consistency with no streaks of yogurt remaining.

Step 4: Create the Oatmeal Base
Pour the wet ingredients into the dry ingredients and stir until just combined. Be careful not to overmix, which can make your oatmeal tough. The batter should be relatively thick but pourable, similar to a muffin batter consistency.

Step 5: Prepare the Cinnamon Swirl
In a small bowl, mix the brown sugar, melted butter, and cinnamon until it forms a thick paste. This creates the signature cinnamon roll flavor that will ribbon throughout your baked oatmeal.

Step 6: Assemble and Swirl
Pour half of the oatmeal mixture into your prepared baking dish. Drizzle half of the cinnamon mixture over this layer. Add the remaining oatmeal batter, then drizzle the rest of the cinnamon mixture on top. Use a knife to create swirls throughout, creating that classic cinnamon roll pattern.

Step 7: Bake to Perfection
Bake for 35-40 minutes until the center is set and the edges begin to turn golden brown. A toothpick inserted into the center should come out mostly clean with a few moist crumbs. For a softer texture, aim for the lower end of the baking time.

Step 8: Create the Protein Glaze
While the oatmeal bakes, whisk together the Greek yogurt, cream cheese, maple syrup, and protein powder in a small bowl. Add almond milk by the teaspoon until you reach a pourable but thick consistency, similar to traditional cinnamon roll icing.

Step 9: Finish and Serve
Allow the High Protein Cinnamon Roll Baked Oatmeal to cool for 10-15 minutes before drizzling with the protein glaze. This cooling period helps the oatmeal set and makes the glaze adhere better without melting completely.

Variations

Blueberry Cinnamon Protein Oatmeal: Transform your High Protein Cinnamon Roll Baked Oatmeal by folding 1 cup of fresh or frozen blueberries into the batter before baking. The blueberries burst during baking, creating pockets of juicy sweetness that complement the cinnamon swirl perfectly. This variation adds antioxidants and a beautiful color contrast to your breakfast.

Chocolate Protein Oatmeal Bake: For chocolate lovers, substitute chocolate protein powder for vanilla in the base, and add 2 tablespoons of cocoa powder to the dry ingredients. Replace the cinnamon swirl with a mixture of 2 tablespoons cocoa powder, 2 tablespoons brown sugar, and 1 tablespoon melted coconut oil. Top with a few dairy-free chocolate chips for an extra indulgent but still protein-rich breakfast option.

Apple Pie Protein Oatmeal: Fold 1 cup of diced apples (preferably Honeycrisp or Granny Smith) into the oatmeal base and increase the cinnamon in the swirl mixture to 1 tablespoon. Add ¼ teaspoon of nutmeg and a pinch of cloves to the cinnamon mixture for a warm apple pie flavor profile that pairs beautifully with the protein-enhanced base. This variation brings additional fiber and natural sweetness to your breakfast.

Storage and Serving

Your High Protein Cinnamon Roll Baked Oatmeal keeps beautifully in the refrigerator for up to 5 days when stored in an airtight container. For longer storage, cut into individual portions and freeze for up to 3 months. Thaw overnight in the refrigerator for the best texture. When reheating, add a splash of milk and microwave for 30-45 seconds, or warm in a 350°F oven for 10 minutes to restore the freshly-baked texture.

For an elevated breakfast experience, serve warm with a dollop of Greek yogurt and a drizzle of pure maple syrup to enhance the cinnamon roll flavors. For a post-workout protein boost, pair a square with a small protein shake or a side of scrambled egg whites. This baked oatmeal also works beautifully as a dessert when topped with a scoop of vanilla protein ice cream or coconut yogurt, creating a healthier alternative to traditional cinnamon roll desserts without sacrificing satisfaction.

FAQs

Can I make this recipe vegan?
Yes! Replace eggs with 2 flax eggs (2 tablespoons ground flaxseed mixed with 5 tablespoons water, left to gel for 5 minutes). Use plant-based protein powder, plant-based yogurt, and plant milk. The texture may be slightly less fluffy but will remain delicious.

How much protein is in each serving?
Each serving contains approximately 15-20g of protein, depending on the specific protein powder used. This makes the High Protein Cinnamon Roll Baked Oatmeal an excellent balanced breakfast option.

Can I use quick oats instead of rolled oats?
Yes, quick oats will work, but the texture will be softer and less defined. Reduce the liquid by 2 tablespoons to compensate for their faster absorption rate.

Is this recipe meal-prep friendly?
Absolutely! This recipe is perfect for meal prep. Bake once and enjoy throughout the week. The flavor actually improves after a day as the spices meld together.

Can I reduce the sugar content?
Yes, you can reduce the maple syrup in the base to 2 tablespoons and use a sugar-free sweetener in the cinnamon swirl. The protein powder often contains sweeteners that help maintain overall sweetness.
