Bananas Foster Baked Oatmeal

I just LOVE Baked Oatmeal and banana baked oatmeal is my go-to on the regular because we always have bananas that need to be used up. To make it other level and worthy of the fanciest brunch ever, I added all the flavor of classic bananas foster because rum before 9 AM isn’t a bad thing.

Baked Oatmeal is made with rolled outs, eggs, sugar and other ingredients that bake up to make this cake-like treat decadent and sweet. It could easily pass for dessert if topped with a scoop of vanilla ice cream or a dollop of whipped cream.

What to Serve It With

This breakfast is hearty enough on it’s own but we also love it with a fresh, light fruit salad.

We also like to serve it alongside a big pile of bacon (this Millionaire Bacon is perfect because of the hint of spice!)

Don’t forget the mimosas!

Bananas Foster Baked Oatmeal is completely dreamy. It’s what oatmeal should be….loaded with caramelized bananas, drenched in a warm rum caramel sauce and creamy like a smooth custard. Drooling yet?
