Who doesn’t want to start their day off with chocolate?

Sure, you could blend up a variety of berries, tropical fruits, and juice, but sometimes dark and luxurious sounds better than bright and light.

And let me tell you, this smoothie tastes rich. Nothing light about it. Well, except in the nutrition facts department.

So many smoothies are high in sugar, thanks to the addition of fruit juice, that they’re more of a dessert than a healthy breakfast or snack.

But not this one.

Naturally sweetened with honey and banana, it has a rich chocolate taste and a decadent, frothy texture thanks to the cacao powder and kefir.

And yes, I said cacao, not cocoa. So, what’s the difference?

Let’s start with what makes them similar. Both start out as beans from the cacao plant. These beans are then milled and processed. And that’s where their paths diverge.

For cacao powder, the beans are processed at a low temperature and then milled into a fine powder. Because the heat that’s applied in processing is minimal, cacao powder retains many of the nutrients found in raw cacao beans, and it has a strong bitter flavor.

Cocoa powder, a staple in many households, is made by fermenting and roasting the beans at a high temperature. They’re also alkalized to reduced acidity, resulting in a powder that’s still bitter, but less so than cacao powder.

Nutritionally speaking, both have just 1 gram of sugar per tablespoon, but cacao powder is significantly richer in minerals.

Specifically, cacao powder is a good source of iron, phosphorus, calcium, magnesium, and potassium.

While you can likely find it at your local health food store, buying it online is always a good way to go, and may even be cheaper.

Now onto the second key ingredient: kefir.

Have you ever had drinkable yogurt? Well, kefir is similar.

A cultured, fermented drink, kefir is a creamy, tart beverage that contains a good amount of protein, calcium, potassium, and B-vitamins. Together, these nutrients can help with bone, muscle, and heart health.

But what makes kefir so special? It’s also a rich source of beneficial bacteria known as probiotics.

While we’re still learning exactly how probiotics affect our wellbeing, some of the more studied benefits include improving gut health (such as relieving symptoms of IBS and IBD), helping with anxiety and stress, reducing LDL cholesterol, and boosting the immune system.

Next, to sweeten this smoothie up a bit, we’re enlisting the help of honey and a banana.

While still a source of sugar, honey does have the added benefit of being rich in antioxidants. Plus, depending on the flowers used to make it, local honey can add lovely floral notes to your smoothie.

And a little sweetness helps to balance the bitter qualities of the cocoa, making it the perfect smoothie to serve your family members something healthy without getting caught!

You can also add a splash of coffee to perk up the flavor and energy level, or top it with some superfood cacao nibs for a finishing crunch!

Finally, bananas. High in potassium and fiber, adding them to your smoothie is a nutritious way to add extra sweetness.

Plus, if you freeze the banana beforehand, you’ll end up with a super creamy smoothie, worthy of enjoying as a dessert, whether in a chocolate based beverage like this one or in a seductively luscious green smoothie.

If you haven’t tried adding a frozen banana to your smoothies yet, do yourself a favor and throw one in the freezer right now!

Just be sure to peel it first.

So, what are you waiting for? Break out the blender and whip up a nutrient-packed, smoothie with a rich, dark chocolate taste!

Cooking By the Numbers…

Step 1 – Measure Ingredients

Measure out your ingredients. For a creamier smoothie, use a frozen banana.

If you don’t have cacao powder, you can substitute in cocoa powder instead; however, you may need to add more cocoa powder, as it doesn’t have as strong of a taste as cacao.

Maple syrup can be substituted for the honey if you prefer.

Step 2 – Blend and Serve

Sweeten It Up

Despite having a deep chocolate color, this smoothie is not overly sweet. If you want to turn it into more of a dessert, you can sweeten it up even more by adding an extra banana (preferably frozen) and another one to two teaspoons of honey or maple syrup.

10 thoughts on “Healthy Chocolate Banana Kefir Smoothie”

  1. I have something similar to this (sans the honey) everyday. I usually don’t use as much chocolate as you do, but I’ll have to try it.

    • This recipe yields 2 servings, so that’s about 6 tbsp. of cacao per serving. A “standard” serving of raw cacao powder is 2.5 tbsp., so that is quite a bit. I would recommend adjusting to taste.

      If you’re concerned about the caffeine content, 6 tbsp. contains about 60 mg of caffeine (though this can vary). A standard cup of coffee has about 95 mg of caffeine.
