Slow Cooker Banana Bread PROTEIN Oatmeal Recipe

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

If you don’t have yourself a slow cooker yet, it’s time to buy one for this recipe alone! 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’re usually pretty cheap if you don’t want to order them online.

All you do for this one is simply add into your slow cooker 2 cups of steel cut oats, 2 teaspoons of ground cinnamon, 2 broken up bananas, 2 tablespoons of a sweetener, 1 teaspoon of vanilla extract, 2 tablespoons of chia seeds, 4 scoops of vanilla or chocolate protein powder, 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 bananas. You could also mash them before adding them into your slow cooker to speed this process up.

That’s it!

You’re done. Throw your lid on and cook it for around 9-10 hours on high and be prepared for your whole house to smell AMAZING!

Once it’s done, let it cool for bit and then portion it out however you want to. I usually make 5 servings and each serving is around 450 grams.

You can eat this cold or reheat it in the microwave for a minute with a little extra milk if it’s too thick. I always top mine with some crushed up pecans and extra banana slices!
