This High Protein Chocolate Peanut Butter Smoothie is one of my favorite high protein snacks. Made with just five simple ingredients, this smoothie is filled with protein, fiber and healthy fats to fuel your day.

Smoothies are one of my go-to’s when I want a QUICK, healthy breakfast or snack. All you have to do is throw everything into a blender, blend it up, and you are ready to go.
the perfect on-the-go snack
One of the best parts about smoothies is you can take them on the go. If I’m running out the door for an appointment or errands, I’ll blend up a smoothie and drink it while I’m driving. I absolutely love this blender because it comes with a screw on lid so you can drink the smoothie RIGHT out of the blender cup. Less time, less dishes, it’s genius.
WHAT YOU NEED
- Frozen ripe banana: Using frozen banana makes the smoothie super thick and creamy, kind of like an ice-creamy texture. The key here is to use RIPE banana. The more brown and speckled the banana, the sweeter your smoothie will taste, which means you don’t need to add any other sweetener! I always keep frozen bananas in my freezer to add to smoothies.
- Protein powder: I always add a serving of protein powder to my smoothies. It makes them more ‘well-rounded’ so you are getting a source of carbs from the fruit, protein from the protein powder, and I always throw in a healthy fat like peanut butter. This combo will keep you fuller and more satisfied for longer!
- Cocoa powder: Adds a delicious rich chocolate taste. Even if I am using chocolate protein powder I will add a tbsp or two of cocoa powder to really amp up the chocolate flavor. Plus, cocoa powder is high in antioxidants that can reduce inflammation, and boosts your serotonin levels (aka chocolate makes you HAPPY!)
- Peanut Butter: I find that adding a source of fats makes smoothies so much more filling! I always buy natural peanut butter and check the ingredient list to make sure it’s just made with peanuts and salt.
- Milk: You can use any type of milk you’d like for this recipe. Sometimes I will use whole milk because it’s high in protein, but almond milk is great if you want it to be lower calorie.
MY FAVORITE PROTEIN POWDER
I tried soooo many protein powder brands over the years searching for my favorite. Some had a gross aftertaste, some were full of questionable ingredients, and some made me feel sick and bloated. I finally found Promix and have never looked back.
Promix uses grass-fed whey and only pure, natural ingredients. It’s made in the USA and doesn’t contain any artificial sweeteners, which I find are the culprit to feeling bloated. They sweeten their protein powder with coconut sugar and use justttt the right amount so its not too sweet but still tastes great.
Each serving has 25 grams of protein, so I add it to my oatmeal, smoothies, pancakes, baking, you name it! They also have a few delicious flavors to choose from – my favorite is the Vanilla Whey Protein Powder because I find it to be the most versatile, but I also LOVE the Peanut Butter.
I have been a Promix partner for over a year now and I truly stand by their products and brand! If you want to try their products, you can use the discount code ‘CLAIRE’ at checkout for 15% off.
