Few breakfasts are as cozy and fuss-free as these Cinnamon Swirl Baked Oatmeal Cups. They capture everything I love about oatmeal—the warm cinnamon scent and hearty oats—alongside a gooey swirl reminiscent of a fresh cinnamon roll. Baking them in single-serving cups makes busy mornings smoother, and they never fail to disappear fast from my kitchen. They are especially perfect for cool Q4 mornings when you crave both comfort and grab-and-go ease.
I started making these during our back-to-school mornings and everyone in my house loves when I pull them from the oven—the aroma alone feels like a warm hug.
Ingredients
- Rolled oats: choose certified gluten-free oats if needed for a nutty flavor and chewy bite
- Baking powder: ensures a light and fluffy texture in each cup
- Ground cinnamon: infuses warming spice throughout the oatmeal and swirl
- Salt: highlights the sweetness and balances flavor
- Milk of choice: brings creaminess dairy or dairy-free both work
- Large egg: binds everything for a cohesive texture
- Maple syrup or honey: only a touch but it gives natural sweetness and depth
- Melted coconut oil or butter: keeps the oatmeal moist and adds richness
- Vanilla extract: enhances all the flavors for a classic bakery aroma
- Brown sugar: dark or light draws out the gooey cinnamon ribbon
- Chopped pecans or walnuts: the textural crunch on top is optional but adds heartiness
Instructions
- Prepare Your Pan
- Grease a 12-cup muffin tin or line with silicone muffin liners Get the pan ready before mixing so the batter retains its lift

- In a separate bowl whisk together your milk egg maple syrup melted coconut oil and vanilla extract Mix until the liquids look uniform and smooth
- Blend Wet and Dry
- Pour wet mixture over the dry ingredients Use a big spoon to gently stir until no dry spots remain but do not overmix so the cups stay tender

- Fill Muffin Cups and Swirl
- Divide oatmeal batter evenly among muffin cups filling each three quarters to the top Drop a teaspoon of cinnamon swirl in the center of each cup Use a toothpick or skewer to twirl the swirl throughout the batter for a marbled look
- Bake to Perfection
- Place pan in the center of your oven and bake for about 22 to 25 minutes Cups are finished when tops look set and slightly golden and a toothpick comes out with only moist crumbs

For me the vanilla extract is the magic touch I have a vivid memory of making a double batch during a weekend sleepover and the kids cheered when they saw the cinnamon swirl hiding inside each cup
