Banana Bread Oatmeal

I’ve had this recipe up my sleeve for about a week and a half now, but just haven’t had time to post it… I’ve been enjoying this breakfast gem in secret all week!

After the half-way success of the gingerbread baked oatmeal, I decided that what makes a truly good baked oatmeal is fruit or vegetable puree (like the pumpkin puree in the baked pumpkin pie oatmeal). It provides thickness, body, and moisture. So, banana bread oatmeal, with mashed up bananas, was a natural next step. I basically just used the pumpkin pie oatmeal recipe and tweaked it to be banana bread flavored. I am happy to report, it was every bit as much of a success as the pumpkin pie oatmeal!

This baked oatmeal is moist, fluffy, thick, hearty and delicious. It tastes just like the best banana bread you’ve ever had and is 10x healthier (very little fat, lower sugar, and tons of fiber). It’s just an all around win!

One more interesting thing about this oatmeal: it’s nice and golden brown when it finishes baking, but as it sits in the fridge during the week it turns a little grey… but that’s just the bananas oxidizing like a peeled banana would if it sat on your countertop. It didn’t affect the flavor at all. So, don’t let that scare you!

Step By Step Photos

mash bananas
Start by mashing your bananas. The more ripe the bananas are, the easier they are to mash. Bananas can seem dry and hard to mash at first, but they tend to get more moist and mushy the more you mash.

measure mashed bananas
Measure the bananas. You want about 1.5 cups. This took me about four medium sized bananas. Start with three and then mash more as neeeded

other ingredients
Whisk the mashed bananas together with the brown sugar, eggs, salt, vanilla, baking powder, cinnamon, nutmeg, and baking soda.

And then it will look like this.

add milk
Next, whisk in the milk.

add oats
Then stir in the old-fashioned oats.

chop walnuts
Roughly chop the walnuts and stir them into the mixture.

pour in baking dish
Pour it all into a non-stick coated glass baking dish. Cover this with foil and bake for 30 minutes. Remove the foil after 30 minutes and bake for another 15 minutes or until the center is solid and the edges are golden brown.

When it comes out, it is golden brown and delicious looking. This picture really does not do it justice. It is AH-MAZ-ING.

golden brown
You can see how it’s kind of golden brown on the edges. Yummmmm.

baked banana bread oatmeal
It’s fantastic plain but I like it with a little milk, and maybe some maple syrup, or even some whipped cream. DELISH! …and very hearty. Because the bananas are so sweet, I might even try it with less brown sugar next time!
