These Cake Batter Overnight Protein Oats are a party waiting to happen! What will you celebrate? Maybe the fact that you can have dessert for breakfast and feel good about it? These overnight protein oatmeal jars are packed with protein, fiber, and volume to keep you feeling full.

In fact, I have a special trick for extra volume and fluff 😉 Instead of using half a cup of liquid to half a cup of oats, double the liquid to one cup, microwave for a couple minutes, then add one-quarter cup more liquid (plus remaining ingredients). Leave in the fridge overnight and wake to fluffy, pudding-like chilled oats. Yumm!

Did you know? Oats are the chief source of avenanthramides, a special class of antioxidants that help lower blood pressure, decrease inflammation, and have anti-itch properties (why oats is often an ingredient in “soothing” lotions and soaps). (source)

Protein recommendations

To keep this vegan and high protein, I added LIV Body Lean Vegan Protein in Cake Batter (how fitting!) This protein powder is great because it contains no artificial ingredients, AND it provides organic superfoods and probiotics. I seriously notice better digestion when I have it everyday versus not. You can use my code “NOEXCUSES” for 20% off all LIV Body products (including their whey protein and beauty products!):

Since this recipe is no bake, you can easily substitute whey, casein, or another vegan blend without other modifications. If using collagen instead of plant-based protein, you may need to reduce the amount of liquid as much as half a cup since collagen is not very absorptive.

Choosing the right oatmeal

The oatmeal I used was quick oats – I just love the fluffier texture it provides! However, you can use old-fashioned oats no problem. I do not recommend steel-cut oats as they will not fluff up as much. Of course, if you need this to be gluten-free, be sure to get certified gluten-free oats!

Sweetener substitutions

It’s probably not a surprise to you that I used my favorite organic stevia blend to sweeten this recipe! It’s what most of my recipes call for, and for good reason. This sweetener is cost-effective, you need half as much as a cup of sugar, it has zero aftertaste, zero calories, and is 100% organic. Did I mention you can also buy it at Walmart?

If you don’t have this particular sweetener, you can use twice as much baking stevia, granulated erythritol, granulated monk fruit sweetener, or liquid stevia drops to taste. You might want to start with a little less sweetener than the recipe calls for if your protein powder is quite sweet.

Other substitutions

I did use nonfat plain Greek yogurt in this recipe… however, if you need this 100% vegan then you’ll want to use a thick, dairy-free yogurt. This coconut milk one is quite a bit thicker than most I’ve tried! You can use vanilla yogurt if you prefer.

This recipe also calls for cashew butter. I used this coconut vanilla cashew butter, but you can totally use plain! Or, if you don’t like cashew butter or are allergic, try white chocolate peanut butter or sunflower seed butter.

Last but not least, I added some pure vanilla extract and butter extract for the ultimate cake batter experience. Butter extract is usually by the vanilla extract but it’s totally optional.

It wouldn’t be CAKE BATTER oats without some natural sprinkles and dairy-free white chocolate chips! AND you can simply switch up the toppings for more flavors (cookie dough, cookies and cream, peaches and cream, strawberries and cream, PB&J, so many options).

Here’s the printable recipe for these Cake Batter Overnight Protein Oats! I’d love for you to rate this recipe or comment below if you try it 😉
