Cinnamon Roll Baked Oatmeal (34g Protein, Single Serve)

This cinnamon roll baked oatmeal is one serving of soft, cake-like protein baked oats with a cinnamon sugar swirl and cream cheese Greek yogurt icing. 34 grams of protein, gluten-free, and it tastes like a cinnamon roll for breakfast.

The second summer ends I want everything cinnamon, and this is what I make on the mornings I don’t have three hours for Memere’s cinnamon rolls. Soft, warm, swirly, and WAY closer to an IKEA cinnamon roll than oatmeal has any right to be.

Cinnamon roll baked oatmeal is a single-serve breakfast made by blending oats, banana, vanilla protein powder, cinnamon, and almond milk into a batter, swirling in cinnamon sugar, and baking it in a small dish until it’s soft and cakey. Topped with a cream cheese Greek yogurt icing, one serving has about 34 grams of protein and takes 32 minutes start to finish.

Why You’ll Love This Baked Oatmeal

• It eats like dessert. Cakey middle, gooey cinnamon swirl, cream cheese icing melting into the top.
• One dish, one serving. No family-size casserole sitting in your fridge all week. Want more? Double or triple it.
• Fall in a bowl. Cozy enough for Christmas morning, quick enough for a Tuesday.

Ingredients for Cinnamon Roll Baked Oatmeal

For the oats

• Certified gluten-free oats: rolled, old-fashioned, or quick all work since they get blended into flour. Skip steel-cut, they stay chewy.
• Banana: the main sweetener and what makes the texture soft and moist.
• Maple syrup: a little extra sweetness. Swap in coconut sugar or light brown sugar if that’s what you have.
• Vanilla protein powder: where most of the protein comes from. Use a vegan protein powder to keep it dairy-free.
• Cinnamon and vanilla extract: the cinnamon roll flavor base.
• Unsweetened vanilla almond milk: any milk works.
• Baking powder: gives it that fluffy, cake-like rise instead of a dense oat brick.

For the cinnamon swirl

• Coconut sugar and cinnamon: stirred together and swirled through the batter. Light brown sugar works too.

For the icing

• Cream cheese and plain Greek yogurt: tangy, thick, and adds even more protein. Vegan cream cheese and vegan yogurt make the whole thing plant-based.
• Powdered sugar: just enough to make it taste like real icing. Sugar-free powdered sweetener works.

How to Make Cinnamon Roll Baked Oatmeal

1. Preheat the oven to 350°F and grease a small oven-safe dish.
2. Blend the oats in a high-speed blender until they turn into a fine flour.
3. Add the banana, maple syrup, protein powder, cinnamon, almond milk, baking powder, and vanilla, then blend on high until smooth.
4. Pour the batter into the dish and let it sit for 5 minutes. It thickens up, which keeps the swirl from sinking.
5. Sprinkle the cinnamon sugar over the top and drag a knife through it in a few S-shapes.
6. Bake for 22 to 25 minutes, until the center is set.
7. Stir the cream cheese, Greek yogurt, and powdered sugar together while it bakes.
8. Let it cool slightly, then spread the icing on top.

Tips and Add-Ins

• Air fryer: split the batter between two small greased ramekins and air fry. Let them cool 5 to 10 minutes before icing.
• Spice it up: a pinch of nutmeg, cloves, or cardamom in the swirl tastes like a bakery cinnamon bun.
• Mix-ins: a drizzle of coconut oil or cashew butter in the batter, or a handful of chocolate chips.

Cinnamon Roll Baked Oatmeal FAQ

What size dish do I need?

I use a small dish about 6 by 4 inches. A small dish gives you a fluffier, taller bake. A wider dish spreads the batter thin and it bakes up flatter and drier. Thrift stores are the best place to find cute little baking dishes for cheap.

Can I use quick oats or steel-cut oats?

Quick oats work, they get blended anyway, but I like the texture of old-fashioned rolled oats best. Steel-cut oats don’t blend down the same way and leave the bake chewy.

Is cinnamon roll baked oatmeal gluten-free?

Yes, as long as you use certified gluten-free oats and check that your protein powder and baking powder are gluten-free too. Regular oats are often processed alongside wheat.

Can I meal prep baked oatmeal?

Yes. Let it cool, then store it airtight in the fridge for about a week, with the icing in a separate container. It also freezes for up to 3 months, before or after baking. Reheat in the microwave for 20 to 30 seconds or in a 350°F oven for 10 to 15 minutes, then add the icing.
