Ingredients
Makes 4 servings
For the Baked Oats
- 2 cups old-fashioned rolled oats
- 2 scoops vanilla protein powder, approximately 60 grams
- 1 1/2 teaspoons baking powder
- 1 1/2 teaspoons ground cinnamon
- 1/4 teaspoon salt
- 1 cup unsweetened milk of choice
- 2 large eggs
- 1/2 cup plain nonfat or low-fat Greek yogurt
- 2 tablespoons maple syrup or honey
- 1 teaspoon vanilla extract
For the Cinnamon Swirl
- 1 tablespoon maple syrup or honey
- 1 teaspoon ground cinnamon
- 1 teaspoon melted butter or coconut oil, optional
For the Greek-Yogurt Icing
- 1/2 cup plain Greek yogurt
- 1 tablespoon maple syrup, honey or powdered sweetener, adjusted to taste
- 1/2 teaspoon vanilla extract
- 1–2 teaspoons milk, as needed for drizzling
Step-by-Step Instructions
1. Prepare the Pan
Preheat the oven to 350°F. Lightly grease an 8-inch square baking dish or line it with parchment paper, leaving enough overhang to lift the baked oats from the pan.
2. Combine the Dry Ingredients
In a large bowl, whisk together the rolled oats, protein powder, baking powder, cinnamon and salt. Break apart any clumps of protein powder before adding the wet ingredients.
3. Mix the Wet Ingredients
In a separate bowl, whisk the milk, eggs, Greek yogurt, maple syrup and vanilla until mostly smooth. Pour the wet mixture into the oats and stir until evenly combined. Let the mixture rest for 5 minutes so the oats begin absorbing the liquid.
4. Add the Cinnamon Swirl
Spread the oat mixture evenly in the prepared dish. Stir together the maple syrup, cinnamon and optional melted butter. Drizzle it across the surface, then use a butter knife to create a loose swirl without mixing it completely into the batter.
5. Bake Until Set
Bake for 25–32 minutes, or until the center is set and a toothpick comes out mostly clean. Protein powders absorb moisture differently, so begin checking near 25 minutes and avoid overbaking.
6. Mix the Greek-Yogurt Icing
Whisk the Greek yogurt, sweetener and vanilla together. Add milk 1 teaspoon at a time until the icing is thin enough to drizzle. Refrigerate the icing while the oats cool for at least 10 minutes.
7. Portion the Baked Oats
Cut the baked oats into four equal portions. Drizzle with the Greek-yogurt icing before serving, or store the icing separately and add it after reheating.

Nutrition values are estimates and will vary based on the protein powder, milk, Greek yogurt, sweetener, optional fat and portion sizes used.
Meal-Prep and Storage Tips
- Refrigerator: Store cooled portions in airtight containers for up to 4 days.
- Keep the icing separate: Refrigerate it in a sealed container and drizzle it over the oats after reheating.
- Reheating: Microwave one portion for 45–75 seconds, adding a splash of milk if the oats seem dry.
- Freezer: Freeze individual un-iced portions for up to 2 months. Thaw overnight in the refrigerator before reheating.
- Travel tip: Pack the icing in a small leak-resistant cup and keep the meal chilled until ready to reheat.
Easy Swaps and Variations
- Add chopped walnuts or pecans for extra crunch.
- Mix diced apple into the batter for apple-cinnamon baked oats.
- Use chocolate protein powder for a chocolate-cinnamon variation.
- Replace the maple syrup with your preferred heat-safe sweetener.
- Add raisins or chopped dates for more natural sweetness.
- Use certified gluten-free oats when needed.
Recipe Success Tips
- Use rolled oats rather than steel-cut oats for the intended texture and baking time.
- Do not overmix the cinnamon swirl; visible ribbons create the cinnamon-roll effect.
- If your protein powder is especially absorbent, add 2–4 tablespoons of extra milk.
- Allow the oats to cool briefly before slicing so the portions hold together.
- Taste the icing before adding more sweetener because protein powders vary in sweetness.
Food-Safety Note
Because this recipe contains eggs and dairy, refrigerate cooled portions within 2 hours. Reheat only the serving you plan to eat and keep the Greek-yogurt icing refrigerated until use.

CIWO Meal-Prep Notes
Protein Cinnamon Roll Baked Oats works best when the serving size is planned around your own calorie, protein and training needs. Nutrition numbers in recipes are estimates because brands, ingredient weights, sauces and substitutions can change the final totals.
Storage, reheating and food safety
Cool cooked food appropriately, portion it into clean covered containers and refrigerate promptly. As a practical rule, many cooked leftovers are best used within about three to four refrigerated days; freeze later-week portions when appropriate. Reheat hot components thoroughly, and keep fresh toppings or cold sauces separate when that improves texture.
Adjust the meal for your goal
For a higher-energy training meal, increase an appropriate carbohydrate portion or add a nutrient-dense side. For a lighter meal, emphasize vegetables and moderate calorie-dense sauces, oils and cheese. For more protein, adjust the main lean-protein portion or pair the meal with a protein-rich side.
Make the nutrition estimate more accurate
Weigh or measure the ingredients you actually use and calculate the batch from their labels, then divide by the number of portions. This is more reliable than assuming every version of the recipe has identical calories or macros.
