Cinnamon Roll Baked Oatmeal

Sunday meal prep that actually makes the week feel manageable. That’s what this is.

Blended cottage cheese and eggs go into the batter for a creamy, high-protein base. A coconut sugar cinnamon swirl goes on top and sinks into the oats while it bakes creating those gooey pockets of cinnamon you want in every bite. A sweet frosting drizzle goes on right before serving so it looks and tastes like an actual cinnamon roll. Nine grams of protein per slice, five days of breakfast handled, one pan.

If you’re already making the pancake breakfast bars or the blueberry muffin overnight oats for the week, this fits right in.

why you’ll love this cinnamon roll baked oatmeal

It tastes like a cinnamon roll for breakfast. Genuinely. The coconut sugar swirl sinks into the oats while it bakes and creates gooey pockets of cinnamon throughout, the frosting drizzle ties the whole thing together, and nobody is going to look at this and think “healthy breakfast.” Blended cottage cheese disappears completely into the batter and bumps each slice up to nine grams of protein without any protein powder involved.

Make it Sunday and breakfast is handled all week. It reheats in under a minute, works dairy-free and gluten-free, and the active time is about 10 minutes. The oven does the rest.

Ingredients you’ll need

• Rolled oats: old-fashioned rolled oats give you the best texture here. Quick oats will work but the result is softer and less chewy. Steel-cut oats do not work — they need much longer to cook and will come out crunchy and undercooked in the center.
• Milk of choice: any milk works. Start with 1.5 cups for a denser, sliceable result. Go up to 2 cups if you want something softer and more spoonable.
• Cottage cheese, blended smooth: the protein base of the batter. Full-fat gives you the creamiest result. Blend it with the milk and eggs before it goes in so it disappears completely into the batter. You cannot taste it, see it, or identify it in the finished bake.
• Eggs: two large eggs or half a cup of egg whites. Eggs give the bake structure so it holds together when you slice it. Without them it will not set properly.
• Maple syrup: sweetens the batter without refined sugar. A third of a cup is the right amount since the cinnamon swirl is adding sweetness on top.
• Vanilla extract: one teaspoon in the batter. This is what makes the whole thing smell and taste like a cinnamon roll rather than just spiced oatmeal.
• Cinnamon and pumpkin pie spice: cinnamon is the dominant flavor. The pumpkin pie spice adds warmth and depth without tasting identifiably like pumpkin spice. It just makes the cinnamon taste more complex.
• Baking powder and salt: baking powder gives the bake a slight lift. Salt makes everything else taste more like itself.

For the cinnamon swirl:

• Coconut sugar: a third of a cup mixed with coconut oil and cinnamon. Coconut sugar has a deeper, more caramel-like flavor than white sugar and gives the swirl that almost brown-buttery quality once it bakes into the oats.
• Coconut oil: two to three tablespoons melted and mixed into the swirl paste. This is what makes the swirl sink into the batter while it bakes and create those gooey pockets rather than sitting as a dry topping on the surface.
• Cinnamon: two teaspoons in the swirl on top of the cinnamon already in the batter. This is the step that makes it actually taste like a cinnamon roll.

For the frosting:

• Powdered monkfruit sweetener: half a cup whisked with two tablespoons of milk until smooth. If you use regular powdered sugar the ratio is the same. The frosting should be thick enough to drizzle in a ribbon but thin enough to flow. Add milk a little at a time until you get there.

How to make high protein cinnamon roll baked oatmeal

Step 1: Preheat, prep, and blend wet ingredients. Preheat oven to 350°F and grease an 8×8 baking dish. Add cottage cheese, milk, eggs, maple syrup, and vanilla to a blender and blend until completely smooth. This is what makes the cottage cheese disappear entirely into the batter.

Step 2: Mix the batter. In a large mixing bowl stir together oats, cinnamon, pumpkin pie spice, baking powder, and salt. Pour the blended wet mixture in and stir until fully combined. The batter will look quite loose and liquid-y. That is correct. The oats absorb the liquid as it bakes.

Step 3: Make the swirl and assemble. Melt the coconut oil and stir in coconut sugar and cinnamon until a thick paste forms. Pour the oat batter into the prepared baking dish and spread evenly.

Step 4: Swirl the cinnamon mixture. Spoon the cinnamon swirl over the top, then use a butter knife to drag through the batter in figure-eight or S-shaped motions. You are not mixing it in fully. You want visible swirl ribbons that sink into the oats while it bakes.

Step 5: Bake. Bake uncovered at 350°F for 35 to 40 minutes until the center is just set when you gently shake the pan and the edges are golden. A toothpick inserted in the center should come out mostly clean with just a few moist crumbs. Do not overbake. The center should still have a very slight jiggle when you pull it. It firms up as it cools.

Step 6: Frost and serve. Let cool for 10 minutes. Whisk powdered monkfruit sweetener with milk until smooth and drizzle over the top before slicing. The frosting goes on warm, not hot. If the bake is too hot the frosting will run off and pool rather than drizzle and set.

Simple swaps for cinnamon roll baked oatmeal

• No cottage cheese? Greek yogurt is the closest swap and works well. The texture will be slightly less custardy but still creamy and the protein content stays high. Same amount, no blending needed.
• No coconut sugar for the swirl? Brown sugar is a direct swap and gives you a similar deep, caramel-like flavor.
• No coconut oil? Melted butter works exactly the same way in the swirl and gives it a slightly richer flavor.
• Want to add protein powder? Stir one scoop of vanilla protein powder into the dry ingredients before adding the wet. Add two to four extra tablespoons of milk to account for the extra absorption. The brown butter blackberry streusel muffins use a similar approach to protein in baked goods if you want another high-protein baked breakfast option.
• Dairy-free? Use plant-based milk, dairy-free yogurt in place of cottage cheese, and coconut oil in the swirl. Everything else stays the same.
• Want individual portions? Divide the batter between lined muffin tins and bake for 18 to 22 minutes. Same swirl technique, same frosting, just portioned individually for grab-and-go.

Meal prep and storage

Bake it Sunday, slice into six portions, store in an airtight container in the fridge, and breakfast is ready every morning. It reheats in 45 to 60 seconds in the microwave. Add a splash of milk before reheating to keep it from drying out and add the frosting fresh rather than storing it on the slices.

The breakfast hot pockets are another strong Sunday prep option that reheat just as well if you want variety in the same week.

Store in the fridge for four to five days. Freeze for up to three months. To freeze, slice and wrap individual portions in parchment or plastic wrap, transfer to a freezer bag, and freeze. Thaw overnight in the fridge or microwave from frozen for 60 to 90 seconds.

Frequently asked questions

Can I use quick oats instead of rolled oats?

Yes but the texture will be softer and less chewy. Rolled oats give you a more substantial, sliceable result. Steel-cut oats do not work here.

Do I have to blend the cottage cheese?

Yes. Unblended cottage cheese leaves visible curds in the batter that do not disappear during baking. Thirty seconds in the blender makes it completely smooth and undetectable.

Why does my batter look so wet?

This is correct. The batter is supposed to look loose and liquid-y before baking. The oats absorb the liquid as they cook. Pour it in, trust the process, and do not add more oats to compensate.
