How to Make High-Protein Cinnamon Roll Baked Oatmeal
Step 1: Prep Your Baking Dish and Oven
Start by preheating your oven to 350°F (175°C) and lightly greasing an 8×8-inch baking dish. This ensures your High-Protein Cinnamon Roll Baked Oatmeal comes out cleanly and bakes evenly, with those perfectly golden edges we all love.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, combine the rolled oats, vanilla protein powder, ground cinnamon, baking powder, and salt. Stir everything together so the flavors will be well distributed throughout the oatmeal bake.
Step 3: Whisk the Wet Ingredients
In a separate bowl, whisk together the almond milk, maple syrup or honey, eggs, vanilla extract, Greek yogurt, and melted butter or coconut oil. This step adds all the moisture and richness the oats need to turn into a fluffy, cake-like bake.
Step 4: Combine Everything and Pour
Pour the wet ingredients into the bowl of dry ingredients. Stir gently until everything is just combined—don’t overmix. Pour this mixture into your prepared baking dish and smooth the top with a spatula for even baking.
Step 5: Swirl in the Cinnamon Goodness
Mix together the almond butter or melted butter, maple syrup, and cinnamon in a small bowl. Drizzle this sweet, spiced swirl over the top of the oatmeal mixture, then use a knife to gently swirl it in, creating those gorgeous cinnamon roll ribbons.
Step 6: Bake to Perfection
Slide your dish into the oven and bake for 30 to 35 minutes, or until the center is set and the edges are beautifully golden. Let it cool for 5 to 10 minutes—just enough time for the flavors to settle and make slicing a breeze.
Step 7: Optional Icing Drizzle
If you’re feeling extra fancy, stir together Greek yogurt, maple syrup, and vanilla extract for an easy “cream cheese” style icing. Drizzle it over the warm oatmeal and get ready for the ultimate cinnamon roll experience in every bite.
How to Serve High-Protein Cinnamon Roll Baked Oatmeal

Garnishes
For an eye-catching (and mouthwatering) finish, top your High-Protein Cinnamon Roll Baked Oatmeal with a generous drizzle of the optional yogurt icing, a sprinkle of extra cinnamon, or even a handful of chopped pecans or walnuts for crunch. Fresh berries on top add a pop of color and a bright, tangy contrast.
Side Dishes
This oatmeal bake is plenty satisfying on its own, but you can serve it alongside a fruit salad, a green smoothie, or a dollop of extra Greek yogurt for a breakfast spread that feels like a weekend treat any day of the week.
Creative Ways to Present
Try baking the oatmeal in individual ramekins for single-serve portions, or cut it into squares and stack them for a brunch buffet. You can even pack cooled slices into lunchboxes for an on-the-go snack that tastes like dessert but is secretly healthy.
Make Ahead and Storage
Storing Leftovers
Leftover High-Protein Cinnamon Roll Baked Oatmeal keeps wonderfully in the fridge for up to 5 days. Simply let the bake cool completely, then cover tightly or transfer to an airtight container. It’s meal prep magic for busy mornings!

Reheating
To reheat, simply microwave individual slices for about a minute or warm a larger batch in a 350°F oven until heated through. Add a splash of milk before reheating to keep things extra moist and delicious.
