What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, making it easy to pull together anytime you want a cozy breakfast.

• Rolled Oats – 2 cups (about 180g), old-fashioned for best texture (avoid instant oats)
• Baking Powder – 2 teaspoons, to give the oatmeal a light, tender crumb
• Ground Cinnamon – 2 teaspoons, the star spice of our cinnamon roll baked oatmeal
• Brown Sugar – ½ cup (100g), packed, for that rich caramel sweetness
• Salt – ½ teaspoon, balances flavors
• Milk – 2 cups (480ml), any kind works; whole milk adds creaminess, or use almond milk for a dairy-free option
• Eggs – 2 large, room temperature, help bind everything together
• Vanilla Extract – 1 tablespoon, pure vanilla really makes the flavors pop
• Unsalted Butter – 4 tablespoons (57g), melted, adds richness
• Light Brown Sugar – ¼ cup (50g), for the cinnamon swirl
• Additional Ground Cinnamon – 1 teaspoon, to mix into the swirl
• Powdered Sugar – 1 cup (120g), for the vanilla glaze
• Vanilla Extract – ½ teaspoon, for the glaze
• Milk or Cream – 2-3 tablespoons, to thin the glaze to a drizzle consistency

For the best results, I recommend using Bob’s Red Mill rolled oats for that hearty chew and Nielsen-Massey vanilla extract for authentic flavor. If you’re craving a seasonal twist, swap the cinnamon swirl with pumpkin pie spice during fall or add fresh berries on top before baking for a fruity note.

Substitutions? Use coconut sugar instead of brown sugar for a lower glycemic index, or swap the dairy milk with oat milk to keep it vegan-friendly (just use a flax egg instead of regular eggs).

Equipment Needed

• 9×9-inch Baking Dish: Glass or ceramic works great for even baking and easy cleanup. I personally prefer a ceramic one because it holds heat nicely.
• Mixing Bowls: At least two—one for the dry ingredients and one for the wet.
• Whisk: To combine ingredients smoothly; a stand mixer is optional but not necessary.
• Measuring Cups and Spoons: Accurate measurements make a huge difference.
• Spatula or Spoon: For mixing and spreading the batter evenly.
• Small Bowl: For preparing the vanilla glaze.
• Oven Mitts: Safety first when pulling that golden baked oatmeal from the oven.

If you don’t have a 9×9-inch dish, an 8×8-inch will work but expect a thicker bake and slightly longer cooking time. When it comes to whisking, I like to keep things simple—no fancy gadgets needed. Just a good old-fashioned balloon whisk or a sturdy spoon will do the trick.

Preparation Method

1. Preheat your oven to 350°F (175°C). Lightly grease your 9×9-inch baking dish with butter or nonstick spray to prevent sticking.
2. Mix the dry ingredients: In a large bowl, combine 2 cups (180g) rolled oats, 2 teaspoons baking powder, 2 teaspoons ground cinnamon, ½ cup (100g) packed brown sugar, and ½ teaspoon salt. Whisk them together to evenly distribute all the spices and leavening agents.
3. Prepare the wet ingredients: In another bowl, whisk 2 cups (480ml) milk, 2 large eggs (room temperature), 1 tablespoon vanilla extract, and 4 tablespoons (57g) melted unsalted butter until smooth and combined.
4. Combine wet and dry: Pour the wet mixture into the dry ingredients. Stir gently with a spatula until just combined—don’t overmix, or the texture can get gummy. The oats will soak up the liquid, so let the batter sit for 5 minutes to thicken slightly.
5. Prepare the cinnamon swirl: In a small bowl, mix ¼ cup (50g) light brown sugar with 1 teaspoon ground cinnamon. Sprinkle about half of this mixture evenly over the bottom of the prepared baking dish.
6. Assemble the baked oatmeal: Pour half of the oat batter over the cinnamon sugar layer. Then sprinkle the remaining cinnamon sugar mixture evenly over the batter. Finally, add the remaining oat batter on top and gently spread to cover the cinnamon sugar swirl. This layering creates that iconic cinnamon roll effect.
7. Bake: Place the dish in the preheated oven and bake for 35-40 minutes. You’ll know it’s done when the top is golden brown and the center is set (a toothpick inserted should come out mostly clean with a few moist crumbs).
8. Make the vanilla glaze: While the baked oatmeal cools for 10 minutes, whisk together 1 cup (120g) powdered sugar, ½ teaspoon vanilla extract, and 2-3 tablespoons milk or cream until smooth and pourable. Adjust the milk quantity for your desired drizzle thickness.
9. Serve: Drizzle the vanilla glaze over warm slices of baked oatmeal. It’s best enjoyed warm but also tastes great at room temperature.

Pro tip: If you find the oats too dry after baking, a quick brush of melted butter before serving adds extra moisture and richness. And if the glaze thickens too much while resting, just whisk in a splash more milk.

Cooking Tips & Techniques

Getting that perfect cinnamon roll baked oatmeal texture is all about balance and timing. Here are some tips I’ve picked up along the way:

• Don’t rush the soaking: Letting the oat mixture rest for a few minutes before baking helps the oats absorb the liquid, creating a tender, creamy texture instead of dry bits.
• Use old-fashioned rolled oats: They hold their shape better than quick oats, giving you that satisfying chewiness. Instant oats tend to get mushy.
• Room temperature eggs and milk: These mix more evenly with dry ingredients, reducing clumps and ensuring a smooth batter.
• Layer your cinnamon sugar: This trick gives you those beautiful cinnamon swirls, just like in a classic cinnamon roll.
• Watch your bake time: Oven temperatures vary, so start checking at 35 minutes. Overbaking can dry it out, while underbaking leaves a raw center.
• Glaze consistency: If your vanilla glaze is too thick, add more milk a teaspoon at a time. Too thin? Toss in a bit more powdered sugar.
• Personal fail alert: Once, I skipped the cinnamon swirl layer and, honestly, it was just oatmeal with cinnamon, not the same magic. Don’t skip that step!

Multitasking tip: While it bakes, clean up your prep bowls and start making that glaze. That way, you’re ready to drizzle as soon as it’s out of the oven.

Variations & Adaptations

Want to mix things up or cater to special diets? No problem! This recipe is super adaptable:

• Vegan Version: Replace eggs with flax eggs (2 tablespoons ground flaxseed + 6 tablespoons water, chilled for 5 minutes) and use almond or oat milk. Swap butter for coconut oil or vegan margarine.
• Gluten-Free: Use certified gluten-free rolled oats to keep it safe, perfect if you’re sensitive but still want that classic baked oatmeal feel.
• Fruit Boost: Add ½ cup of diced apples or pears into the batter for natural sweetness and texture. Blueberries or raspberries work beautifully in summer.
• Spice It Up: Add ¼ teaspoon nutmeg or cardamom to the cinnamon sugar swirl for a warm spice twist.
• Nutty Delight: Sprinkle chopped pecans or walnuts on top before baking for crunch and extra flavor.

One of my favorite tweaks is swapping half the brown sugar with maple syrup and adding toasted coconut flakes on top—a tropical spin that still feels cozy. Feel free to customize based on what you’ve got or what you’re craving.

Serving & Storage Suggestions

This cozy cinnamon roll baked oatmeal is best served warm, right after you drizzle the vanilla glaze. It pairs wonderfully with a cup of coffee or a glass of cold milk—perfect for a comforting start to your day.

For a full breakfast, serve alongside fresh fruit, Greek yogurt, or scrambled eggs to balance sweetness with protein and freshness. If you’re enjoying it as a snack or dessert, a dollop of whipped cream or a scoop of vanilla ice cream wouldn’t hurt.

Storing is simple: cover leftovers tightly with plastic wrap or transfer to an airtight container. It keeps well in the refrigerator for up to 4 days. To reheat, pop individual portions in the microwave for 30-45 seconds or warm in a 325°F (160°C) oven for 10 minutes until heated through.
