🔖 Recipe Ingredient Notes

Collagen Peptides — Many High Protein Oats recipes call for vanilla protein powder, whey protein powder, or chocolate protein powder. Although that's acceptable to use, I prefer using a scoop of Collagen Peptides Powder. Not only is it tasteless and mixes well, but one scoop adds 10 grams of protein! Collagen Peptides also support your skin, hair, and joints. How are your skin and hair doing? Mine can definitely use a little boost! 😉
Oats — Oats are usually recommended for those trying to lower their cholesterol. Although oats are pretty bland on their own, they do a fantastic job of soaking up the flavor of the other delicious ingredients they're mixed with. You'll want to make sure to use Old Fashioned Oats or quick oats instead of Steele Cut Oats, which need to be cooked.
Spices — I add a pinch of cinnamon to this recipe, but you can add your favorite spices.
Peanut Butter — Add smooth or crunchy peanut butter to your protein oats, or use low-fat peanut butter, if you prefer. Feel free to add anywhere from 1 teaspoon to 1 tablespoon peanut butter.
Yogurt — Non-flavored Greek yogurt or vanilla yogurt work well in this recipe. Steer away from flavored, high-sugar yogurts.
Nuts — I like to top the finished Protein Overnight Oats with various nuts. I don't add them with the other ingredients because they would soften overnight. Besides pistachios, you can use walnuts, cashews, or almonds. If you don't like nuts, add shredded coconut or a few blueberries instead.
Milk — Although I use almond milk, you can substitute whole, skim milk, soy milk, or oat milk.

🤷🏻‍♀️ Recipe FAQs

Can you add protein powder to oats?

Yes, protein powder can be added to overnight oats. Choose the right flavor that will complement the rest of the ingredients in the recipe. Non-flavored or vanilla-flavored protein powders are the best options.

Another great alternative is adding collagen peptides instead. Collagen is flavorless, high in protein, and blends very well. Not to mention it has a ton of benefits for your joint and bone health.

Can eating oatmeal make me gain weight?

Like eating any other food, moderation is the key when it comes to eating protein overnight oats. Since oats are filling, you only need ⅓ of a cup. The other ingredients you add will make a difference too. For example, almond milk adds 15 calories per ½ cup, while 2% milk adds 122 calories per ½ cup.

The calories can skyrocket from there by adding sweeteners, fruit, fats, and nuts. The ingredients in this overnight oats recipe were carefully considered and balanced to give you plenty of protein without a ton of extra calories.
