Chef's Notes

Recipe Sugar – I did not include any added sugar in this recipe because I used very brown bananas. The more brown your bananas, the sweeter this baked oatmeal will be. If you’re using unsweetened milk and your bananas are not over ripe, I would suggest adding 2-3 tablespoons of brown sugar to bananas while mashing. OR you could just serve with a little maple syrup. Adjust according to your sweetness preference!
Milk – Feel free to use your choice of milk here. Whether you use cow’s milk,  goat’s milk or a dairy-free alternative. For a richer flavor, you could also do part half & half or canned coconut milk.
Half the recipe – For a smaller batch, cut the ingredients in half, mix as directed and bake in a 8×4 medium loaf pan; 375ºF for 20-25 minutes.
Double the recipe – To feed a crowd, double the ingredients and mix as directed; bake in a 9×13 pan for 25-30 minutes, until edges are golden.
Mix-Ins – Feel free to do a combo of any of these mix-ins as well. For example, blueberries + walnuts. Or blueberries + peanut butter. Or include peanut butter in all three variations. This recipe is a great base – have fun with it!

Just made again this weekend! Love this recipe and how easy it is to mix it up with whatever you have on hand! Great for breakfast, snack or dessert!

J poteau ★ 5.0/5

This was fantastic!! Can you make ahead and bake next day?

Stacy ★ 5.0/5

Great way to use those left over bananas without making a cake, or bread! Added peanut butter and chocolate chips this time, think I’ll go blueberry peanut butter next! PBJ?

Peggy ★ 5.0/5

This is my favorite meal prep breakfast recipe! I make the banana bread style as a double recipe. I cut it into 15 pieces and freeze them individually. I pull them out, defrost a bit in the microwave, and then cook for about 2 minutes. I skip the milk (they are almost bread consistency), put a little honey on it and am ready to go! It’s also great to send with my husband in his truck for the week! (HEADS UP: I did print the 2x recipe the second time I made them. All of the items on the base recipe except bananas did not double the measurements).

Tori ★ 4.0/5

I made the base recipe. Really simple and so easy to substitute ingredients you already have. I cut into bars and froze to eat during the week. Very moist and not too sweet.

Veronique Phelps ★ 5.0/5

Loved this recipe. Simple ingredients, quick to throw together, and most importantly, a healthy breakfast that the entire family can enjoy (including my 10 month old). Substituted flax for chia seeds and it worked wonderfully. Thanks Ashley!

Becky ★ 5.0/5

This recipe is amazing!! We make the blueberry version 2-3x per week and it disappears every time. (Also great with other frozen fruits) Super toddler friendly and healthy.

Katie ★ 5.0/5

This is going to be my go-to baked oatmeal recipe!
