This Cinnamon Roll Oatmeal recipe blends the comforting flavors of a cinnamon roll with the hearty satisfaction of baked oats. It’s an easy breakfast that tastes indulgent while still being nourishing—high in fiber and perfect for busy mornings. My family loved it the first time I made it; the oats bake up chewy and tender with a warm cinnamon-brown sugar note and a simple vanilla glaze on top.

The combination of old fashioned oats, instant oats, cinnamon, brown sugar and a touch of almond butter gives this baked oatmeal a rich, dessert-like flavor without being overly sweet. It’s quick to mix together, bakes in a single pan, and makes a batch that’s easy to slice and reheat throughout the week. If you enjoy baked oatmeal classics, this version delivers on flavor and convenience.
Ingredients for Cinnamon Roll Oatmeal
- Rolled oats (old fashioned): Flat, flaky oats that absorb liquid well and hold their texture when baked.
- Quick oats (instant): Added to prevent the bars from becoming too dense after baking.
- Brown sugar: Adds warmth and depth from its molasses content.
- Cinnamon: Essential for that classic cinnamon roll flavor; add more if you like extra spice.
- Baking powder: Provides a little lift for a lighter texture.
- Eggs: Give structure and help the oatmeal hold together as bars.
- Milk: Any milk will work; 1% is used here for a lighter result.
- Vanilla: Pure vanilla enhances the overall flavor.
- Almond butter: Adds richness, protein, and a hint of nutty flavor; any nut butter can be substituted.
- Glaze ingredients: Unsalted butter (melted), vanilla, milk, and powdered sugar to create a smooth vanilla glaze for drizzling.
How to make Cinnamon Roll Oatmeal
- Preheat the oven to 350°F and line an 8×8-inch baking dish with parchment paper.
- In a medium bowl, combine 2 cups old fashioned oats, 1 cup instant oats, 1/2 cup brown sugar, 1 1/2 tablespoons ground cinnamon, and 2 teaspoons baking powder. Stir to mix evenly.
- In a separate bowl, whisk together 2 eggs, 1 cup milk, 1 teaspoon vanilla, and 1/3 cup almond butter until smooth.
- Pour the wet ingredients into the dry and stir until fully combined. Spread the mixture into the prepared pan and smooth the top.
- Bake for about 35 minutes, or until a toothpick inserted near the center comes out clean.
- While the oatmeal bakes, whisk together the glaze: 2 tablespoons melted unsalted butter, 1/2 teaspoon vanilla, 1–2 tablespoons milk, and 1/2 cup powdered sugar. Adjust milk to reach your desired drizzle consistency.
- When the baked oatmeal comes out of the oven, let it cool for 5 minutes, then drizzle the glaze over the top. Cut into squares and serve warm.

Baked Oatmeal Tips
This baked cinnamon roll oatmeal is forgiving and easy to adapt. Here are a few suggestions to make it turn out even better:
- Glaze only after the oatmeal is fully cooked and has cooled for a few minutes; pouring glaze onto hot, underbaked oatmeal can cause it to sink in instead of sitting on top.
- For extra protein, add one scoop of vanilla protein powder and an additional tablespoon of milk to keep the batter moist.
- Use certified gluten-free oats to make the recipe gluten-free.
- Swap almond butter for peanut butter, cashew butter, or sunflower seed butter to suit preferences or allergies.
- For a nuttier crunch, sprinkle chopped nuts or a few rolled oats on top before baking.
Tips for storing and reheating
Store leftover baked oatmeal in an airtight container in the refrigerator for 4–5 days. Reheat individual squares in the microwave for about 30 seconds or until warmed through. You can also enjoy them cold with a spoonful of yogurt or a drizzle of extra milk.
