Ingredient Tips for Baked Oatmeal

Oatmeal: Old-fashioned oats (AKA rolled oats) are less processed, so they retain their shape and texture better. Other kinds of oatmeal will produce a softer texture, but can still be used.
Eggs & Milk: To ensure this baked oatmeal is fluffy and holds together well enough to be sliced, eggs and milk are essential. You can swap in almond or oat milk.
Sweetener & Flavoring: Brown sugar and cinnamon are cozy and comforting. For your own signature flair, try adding nutmeg, coconut extract, or pumpkin spice.
Topping: Butter is blended with oats and brown sugar, making a sweet crumble topping.

Tasty Topping Options

The oat topping used in this recipe gives a nice sweet crunch when baked, but there are so many fun options to choose from!

Swirl on cream cheese frosting, then top with berries or bananas. Try peanut butter with sliced apples, too.
For a fun twist, add strawberry jam and mini chocolate chips.
A splash of cream with fresh berries makes it extra special.
For a dessert-style dish, top bars with ice cream and a drizzle of caramel, honey, or maple syrup.
