What Kind of Oats Should I Use?

Old-fashioned rolled oats are the best choice for this recipe. They offer the ideal texture that holds up to baking and absorbs the cinnamon and vanilla flavors without becoming mushy. Avoid using quick oats or steel-cut oats, as they won’t yield the same baked structure or softness.

How To Make the High-Protein Cinnamon Roll Baked Oatmeal

Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C). Lightly grease an 8×8-inch baking dish or line it with parchment paper.

Step 2: Mix the Dry Ingredients

In a large bowl, combine the rolled oats, vanilla protein powder, baking powder, cinnamon, and salt.

Step 3: Add the Wet Ingredients

In another bowl, whisk together almond milk, Greek yogurt, maple syrup, egg, coconut oil, and vanilla extract. Pour the wet mixture into the dry ingredients and stir until fully combined.

Step 4: Prepare the Cinnamon Swirl

In a small bowl, mix together the brown sugar and cinnamon for the swirl. Pour half the oat mixture into the baking dish, then sprinkle half the swirl mixture on top. Repeat with the remaining oat mixture and swirl topping. Use a butter knife to gently swirl through the batter.

Step 5: Bake It

Place the dish in the preheated oven and bake for 35-40 minutes, or until the top is golden and set in the center.

Step 6: Cool and Glaze (Optional)

Let it cool slightly before drizzling with a bit of cream cheese icing or yogurt glaze if you like a classic cinnamon roll finish.

Serving and Storing This Protein-Packed Oatmeal

This baked oatmeal is perfect straight from the oven, but it’s just as good chilled or reheated. Slice it into squares for an easy grab-and-go breakfast. Store leftovers in an airtight container in the fridge for up to 5 days or freeze for up to 2 months. For reheating, microwave a portion for 30–60 seconds or pop it into a toaster oven until warmed through.
