Dark Chocolate Peanut Butter Collagen Smoothie {with Dates}

A delicious and healthy dark chocolate peanut butter smoothie with collagen protein, naturally sweetened with dates. What is so exciting about this smoothie is that yes, it tastes like chocolate, but uses 100% cacao powder which is not only anti-inflammatory but great for brain health!

Honestly, I don’t care much for peanut butter unless it’s paired with chocolate. Who doesn’t love the flavors of chocolate and peanut butter?

Smoothies are great options to fill in those nutrient gaps plus they’re quick and easy to make. This smoothie can easily help you reach a higher protein and fiber intake. Plus, it actually tastes good! This could be a high protein snack or even consumed as a meal. I have been on a smoothie kick for lunch lately!

Reasons I Love This Collagen Smoothie:

  • Anti-inflammatory properties & improved brain function. Cocoa is now considered a “superfood” because studies are showing that it can enhance immune function and contribute to lower inflammation. Cacao powder is rich in polyphenols which may improve cognition and even enhance mood. Dates have anti-inflammatory properties as well! Read more about this below!
  • It incorporates collagen protein. While there is still much more research that needs to be done, collagen protein is especially important for bone and joint health. The potential anti-aging benefits are exciting for women, though. A recent review of studies found that oral collagen consumption may improve skin moisture, elasticity, and hydration!
  • Peanut butter + chocolate heaven. No refined sugars here yet you still get that rich, chocolatey flavor. It’s super simple to make, too – just 6 simple ingredients.
  • Packed with protein, fiber and antioxidants. This smoothie has 26 grams of protein and 6 grams of fiber. Dates are rich in antioxidants that help lower the risk of several chronic diseases.

Smoothie Ingredients

The ingredients for the dark chocolate collagen smoothie on a counter.

This smoothie makes one serving (about 10-12 ounces). Adjust the ingredients to your preferences! This smoothie is easily customizable.

  • Unsweetened Almond Milk (1 cup) or preferred milk. Skim milk would increase the protein content.
  • Unsweetened Dark Cacao Powder (1 tablespoon). I used Hershey’s Special Dark 100% cacao powder.
  • Collagen Protein (4 tablespoons or serving size listed on label). My go-to is the Vital Protein Collagen Peptides. Sub with any protein powder you prefer!
  • Peanut Butter (1 tablespoon)
  • Medjool Pitted Dates (2). I love Natural Delights Pitted Medjool Dates and find they are pretty soft. Talk about softening the dates.
  • Ice Cubes (about 4 large ice cubes).
  • Frozen Banana, optional. Mixed berries or spinach could also be added if consuming this smoothie as a meal.

Peanut Butter Chocolate Smoothie Instructions

This smoothie has all the “traditional” chocolate and peanut butter flavors but with nutritional benefits that you might not think about. Dates are high in fiber and provide a natural sweetness to this smoothie without the need for any added sugar.

Both dates and dark chocolate contain flavanols which have been shown to lower inflammatory markers and improve brain function. There is potential for both of these ingredients to lower cognitive disorders, like dementia and Alzheimer’s disease.

I switch between whey and collagen protein powder when making smoothies. Although we don’t have a large amount of evidence regarding collagen supplements and their role in anti-aging – it’s worth a try! I know a lot of dietitians are now starting to use it.

  1. Add all ingredients to a high speed blender and puree for at least 45 seconds, until smooth and well-combined.
  2. Pour into a glass and enjoy! This smoothie is best if consumed immediately.

The dates should be very soft or else the blender may leave small chunks. To soften the dates, place them in a bowl with hot water and allow them to soak for 10-20 minutes prior to blending.
