This high-protein cinnamon roll baked oatmeal transforms ordinary breakfast into a guilt-free treat that tastes like dessert. The warm cinnamon aroma fills your kitchen while you get all the nutrition of a balanced breakfast with the satisfaction of your favorite pastry.

I created this recipe during my fitness journey when I craved something comforting but nutritious. Now it's become my Sunday ritual to prepare this for busy weekday mornings, and it makes the whole house smell like a bakery.

Ingredients

  • Rolled oats: Provide fiber and sustained energy release to keep you full all morning
  • Nonfat Greek yogurt: Adds creaminess and protein without excess calories
  • Liquid egg whites: Boost the protein content without adding fat
  • Monk fruit sweetener: Gives natural sweetness with zero calories or sugar impact
  • Almond milk: Keeps the recipe light and dairy flexible
  • Vanilla extract: Enhances the dessert flavor profile without added sugar
  • Ground cinnamon: Provides warming flavor and has natural blood sugar balancing properties
  • Baking powder: Ensures the oatmeal rises properly for a fluffy texture
  • Fat-free cream cheese: Creates an authentic cinnamon roll frosting experience without the guilt

Step-by-Step Instructions

Mix Wet Ingredients:
Thoroughly whisk together the almond milk, Greek yogurt, egg whites, vanilla, and sweetener until completely smooth. This forms the protein-rich base that will give the oatmeal its custard-like texture. Take your time here to ensure everything is fully incorporated for the best consistency.
Add Dry Ingredients:
Gently fold in the oats, cinnamon, baking powder, and salt until evenly distributed. Be careful not to overmix as this can make the final texture tough. The mixture will look loose at this stage but will thicken significantly during the soaking period.
Soak Overnight:
Cover the bowl and refrigerate for at least 4 hours, preferably overnight. This critical step allows the oats to absorb the liquid and soften while the flavors meld together. The mixture will transform from soupy to thick and pudding-like during this time.
Bake To Perfection:
Transfer the soaked mixture to your prepared baking dish, spreading evenly to the corners. Bake at 350°F for 45-60 minutes until the edges become golden and slightly pull away from the sides. The center should be set but still maintain a slight jiggle for the perfect texture.
Create The Frosting:
Whisk the cream cheese with sweetener until smooth, then gradually add almond milk until you reach a pourable consistency. The frosting should be thin enough to drizzle but thick enough to not completely soak into the oatmeal.

The moment I pull this from the oven always takes me back to Sunday mornings with my grandmother, who made cinnamon rolls from scratch. This healthier version lets me enjoy those same comforting flavors while supporting my nutrition goals. The vanilla and cinnamon aroma that fills the kitchen is truly the best part of the process.

Meal Prep Magic

This baked oatmeal is designed for busy lifestyles. After cooling completely, cut into individual portions and store in airtight containers. They'll keep perfectly in the refrigerator for 5 days. For longer storage, wrap portions individually and freeze for up to 3 months. A quick 60-90 seconds in the microwave returns them to their warm, comforting state.

Customization Options

This recipe welcomes personal touches without compromising its nutrition profile. Add fresh berries before baking for bursts of flavor and antioxidants. Stir in chopped apple and extra cinnamon for an apple pie variation. For texture contrast, sprinkle chopped walnuts or pecans on top before baking to add healthy fats and crunch. The base recipe remains macro-friendly while adapting to your taste preferences.

Serving Suggestions

Enhance your baked oatmeal experience by pairing it with complementary sides. A dollop of additional Greek yogurt adds extra protein and creaminess. Fresh berries alongside provide color and antioxidants. For special occasions, a small drizzle of pure maple syrup elevates the cinnamon roll experience. Consider serving with a protein shake on the side for an ultra-high protein breakfast that will keep you satisfied until lunch.

Yield: 9 Servings (9 squares)

Dietary: Vegetarian, Gluten-Free

Ingredients

→ Main Batter

01 1 cup rolled oats
02 1 cup unsweetened vanilla almond milk
03 ½ cup nonfat plain Greek yogurt
04 ½ cup liquid egg whites
05 2 tablespoons monk fruit sweetener
06 1 teaspoon vanilla extract
07 1 teaspoon ground cinnamon
08 ½ teaspoon baking powder
09 ¼ teaspoon salt

→ Frosting

10 2 tablespoons fat-free cream cheese
11 2-3 tablespoons unsweetened vanilla almond milk
12 1 tablespoon monk fruit sweetener

Instructions

Step 01

In a large bowl, whisk together the unsweetened vanilla almond milk, nonfat plain Greek yogurt, liquid egg whites, vanilla extract, and monk fruit sweetener until well combined. Add the rolled oats, ground cinnamon, baking powder, and salt to the wet ingredients. Stir until fully incorporated. Cover the mixture and let it soak for several hours or overnight in the refrigerator to allow the oats to absorb the liquid and expand.

Step 02

Preheat your oven to 350°F (175°C). Lightly grease an 8×8-inch baking dish or line it with parchment paper. Pour the soaked oat mixture into the prepared baking dish, spreading it evenly. Bake in the preheated oven for 45-60 minutes, or until the center is set and a toothpick inserted comes out clean. Remove from the oven and allow it to cool slightly.

Step 03

In a small bowl, whisk together the fat-free cream cheese, monk fruit sweetener, and enough unsweetened vanilla almond milk to achieve a smooth, drizzle-able consistency.

Step 04

Drizzle the frosting over the baked oatmeal. Cut into 9 equal pieces and serve warm. Store any leftovers in an airtight container in the refrigerator for up to 5 days. Reheat individual portions in the microwave as needed.

Notes

  1. Allow the batter to soak overnight for better texture and flavor.
  2. Store leftovers in an airtight container and reheat for convenience.
