Slow Cooker Banana Bread PROTEIN Oatmeal Recipe

Slow Cooker Banana Bread Protein Oatmeal Recipe
Written by The Protein Chef

I’ve wanted to do this for awhile and today is the day we start it. Slow Cooker Sunday (#SlowCookerSunday) starts now! From here on out (or until you guys get sick of them), I’ll be making a new slow cooker recipe every single Sunday. If you don’t have yourself a slow cooker yet, it’s time to buy one. Today we take oatmeal to the next level with this super easy Slow Cooker Banana Bread Protein Oatmeal recipe. It only takes a couple minutes to prep and it’s gonna change your morning routine!

We start this off with a little tip. If you hate cleaning up your slow cooker after your meal prep (like me), use one of these liners. You should be able to find them locally and they are usually pretty cheap if you don’t wanna order them online. Now add into your slow cooker 2 cups of steel cut oats, 2 teaspoons of ground cinnamon, 2 ripe bananas either broken up or you can mash them before you add them in, 2 tablespoons of a sweetener, 1 teaspoon of vanilla extract, 2 tablespoons of chia seeds, 4 scoops of Labrada Nutrition 100% Whey vanilla protein powder (chocolate for a chocolate banana taste), 1/2 teaspoon of salt, 2 tablespoons of melted butter, 4 cups of unsweetened vanilla almond milk, and 4 cups of water.

Mix everything together while mashing in your banana if you didn’t pre-mash it then throw your lid on and cook it for around 9-10 hours on high. Be prepared for your whole house to smell delicious during this time (which is also great to wake up to if you throw this on before bed).

Once done, let it cool and then portion it however you want to. I usually make 5 servings and each serving is around 450 grams. As for the taste…it’s like a banana bread, banana pie combo with just the right amount of sweetness!  Oh, and you can eat this cold or re-heat it in the microwave for a minute or a two with a little extra milk if it’s too thick. I always top mine with some crushed up pecans and extra banana slices too.

Other than that, I want you guys to start using the hashtag #SlowCookerSunday when you make these so I can feature you. Every so often I’ll choose my favorite pics and we’ll do something unique for those people!
