Soft Cinnamon Roll Baked Oatmeal topped with brown sugar cinnamon and a simple glaze. An easy make-ahead breakfast with all the flavor of a cinnamon roll.
In a large mixing bowl (or directly in the casserole dish), mix the wet ingredients and dry ingredients together in one bowl: bananas, rolled oats, maple syrup, Greek yogurt, eggs, milk, vanilla, cinnamon, salt and baking powder. Combine the oat mixture well (I like to use a whisk).
Next, pour the oatmeal mixture into a non-stick or greased casserole dish.
Combine brown sugar and cinnamon in a small bowl and sprinkle evenly on top of the oatmeal mixture.
Bake oatmeal in the oven for about 30-35 minutes until golden brown and firm in the middle.
To make the glaze, combine powdered sugar and milk. Drizzle on top of the cinnamon roll baked oats and serve warm. Store leftovers in an airtight container for up to 5 days.
Notes
Don't overbake. Remove the baked oatmeal when the center is set and no longer looks wet or jiggly. It will continue to firm up as it cools, and overbaking can make it dry.
Let it cool before glazing. Give the baked oatmeal 5–10 minutes to cool before adding the glaze. This also gives it time to set so it's easier to slice.
Storage: Refrigerate leftovers in an airtight container for up to 5 days. Reheat individual slices for 30–60 seconds in the microwave. For the freshest result, add the glaze after reheating.
