Cooking Steps
- Prepare The Oven:
- Preheat your oven to 325 degrees Fahrenheit and lightly grease a 9 by 13 inch baking pan using nonstick spray or a thin layer of butter to prevent sticking.
- Mix The Wet Ingredients:
- In a large bowl whisk together the eggs milk melted butter or coconut oil maple syrup brown sugar and vanilla extract until fully combined and smooth.
- Combine Dry Ingredients:
- Add the oatmeal baking powder and ground cinnamon to the wet mixture and stir everything gently but thoroughly so the flavors blend evenly.
- Let Batter Rest:
- Allow the oatmeal batter to sit for about 10 minutes so the oats can absorb the liquid and thicken the mixture a bit.
- Bake The Oatmeal:
- Pour the oatmeal batter into your prepared baking dish spreading it evenly then bake for 20 to 25 minutes or until the top is golden brown and set.
- Prepare The Icing:
- While the oatmeal bake is in the oven whisk together powdered sugar and a tablespoon or two of milk in a small bowl until you achieve a smooth icing. Adjust the thickness by adding more milk if too thick or powdered sugar if too thin.
- Cool And Serve:
- Let the bake cool for about 10 minutes once out of the oven then slice into squares drizzle generously with the icing and enjoy while warm.

One of my favorite things about this oatmeal bake is how it manages to capture the indulgence of cinnamon rolls without the fuss of dough or frosting. Serving it warm right from the oven feels like a hug on a plate especially when the cinnamon aroma fills the room.
Best Storage Practices
Store any leftovers in an airtight container in the refrigerator for up to four days. Reheat individual portions briefly in the microwave or oven to bring back that fresh-baked warmth. This bake can also be frozen in portions for up to three months. Thaw overnight in the fridge and warm before serving.
Ingredient Swaps
Use plant-based milk like almond or oat milk and coconut oil instead of butter for a vegan-friendly version. Experiment with adding chopped nuts such as pecans or walnuts in the batter for extra crunch. You can also mix in dried fruits like raisins or chopped dates to add natural sweetness and texture that pairs wonderfully with the cinnamon flavor.
Serving Pairings
Serve alongside a dollop of Greek yogurt or a scoop of vanilla ice cream for brunch indulgence. Fresh fruit like sliced apples or pears complements the spice and sweetness beautifully. A hot cup of coffee or chai tea turns this oatmeal bake into a complete comforting meal.

This oatmeal bake combines comfort and nutrition in a simple dish that feels like a warm embrace on a cool morning.
