If you are an oatmeal fan, the recipe I’m sharing in this post is guaranteed to be added to your oatmeal-making rotation. Baked oatmeal is one of our favorite make-ahead breakfast dishes and this spiced brown sugar oatmeal version is a certified family-favorite in my house. 

What is Baked Oatmeal?

Baked oatmeal is a breakfast casserole that is generally made with a combination of quick-cooking or regular oats, cream or milk, eggs, and sugar. This basic baked recipe oatmeal is an extremely forgiving and customizable dish. If necessary, nut milk can be used in place of the dairy ingredients and non-sugar sweeteners can replace any measure of sugar in a recipe. Flavors can be changed up in a pan of baked oatmeal according to preference, or seasonally by adding in whole fruit or fruit puree, and spices.  And there are a number of delicious toppings and combinations of toppings that would be delicious served with it!

Baked oatmeal has been compared to bread pudding in several blog posts I’ve read, but my kids always refer to this breakfast casserole as breakfast CAKE when I make it! I would definitely liken this dish more to a breakfast cookie bar, a soft breakfast cookie, or indeed a breakfast cake rather than bread pudding, truthfully. It retains much more texture than bread pudding does in my opinion due to the nature of the oats. 

We like to eat slices of baked oatmeal warm, served on its own with a side of fresh fruit (especially summer berries). However, I also enjoy eating a slice of baked oatmeal served in a bowl and nestled in a shallow pool of creamy, ice-cold milk! Warm, spiced oatmeal, and milk is just such a comforting combination!

This recipe makes a large 9×13 in pan full of this delicious breakfast treat. We like to bake this on a Sunday morning and have it around in our fridge to make our mornings easy for the next few days. You could also slice this into individual food containers to food prep for busy mornings on the go. It keeps beautifully in the refrigerator for up to 7 days!

Happy eating, my friends!
