Chocolate Banana Oat Smoothie

If you’re looking for a smoothie that tastes like dessert but is packed with nourishing ingredients, you’re in the right place. This chocolate banana oat smoothie is thick, creamy, and tastes like a cross between a milkshake and a frosty; yet it’s made with simple, wholesome ingredients you likely have on hand.

As a former gym owner and nutrition coach, I’ve helped hundreds of busy women find quick, high protein breakfast options they actually enjoy. Smoothies like this one are one of my favorite recommendations, especially for those who need something filling before or after a workout. The combo of protein and carbs in this smoothie makes it both satisfying and energizing, and it takes just minutes to make.

If chocolate smoothies are your thing, don’t miss my Tahini Chocolate Smoothie, Chocolate Strawberry Banana Smoothie and Chocolate Mango Smoothie. These are all perfect for a protein packed breakfast or post-workout snack.

Ingredient spotlight

• Banana – Naturally sweetens the smoothie and adds creaminess, especially when frozen. The riper the banana, the sweeter the smoothie.
• Oats – Use rolled or quick oats for best texture. They also make the smoothie really thick and creamy.
• Cacao Powder – Provides rich chocolate flavor with antioxidants and less bitterness than cocoa powder.
• Chocolate Protein Powder – Boosts protein and gives the smoothie a thick, milkshake like texture. Vegan protein powder works especially well. Need help with protein powder? Be sure to check out my article on adding protein powder to smoothies.
• Almond Butter – Makes the smoothie more filling and creamy. Any nut or seed butter can be used as a substitute (another great option would be tahini).

Ingredients

• 1 banana - medium
• 1 tablespoon cacao powder
• ¼ cup rolled oats
• 1 serving chocolate protein powder
• ¾ cup dairy free milk
• 1 tablespoon almond butter

Instructions

• Measure the ingredients into a high speed blender in the order listed.
  1 banana, 1 tablespoon cacao powder, ¼ cup rolled oats, 1 serving chocolate protein powder, ¾ cup dairy free milk, 1 tablespoon almond butter
• Blend on high until smooth. Enjoy immediately.

Equipment

• 1 High speed blender

Notes

• Use frozen bananas for the best texture and taste. Frozen bananas chill the smoothie and make it thick and creamy. If using fresh banana, add 1/4–1/2 cup ice and reduce the liquid by 1/4 cup.
• Add more or less liquid to adjust the texture. Use less for a thicker smoothie, more for a thinner consistency.
• If not using protein powder, add a sweetener. The protein powder adds sweetness and protein. If skipping it, add maple syrup, honey, or 1–2 medjool dates to balance the flavor.

Common questions

Why put oats in a smoothie?

Oats are a great source of protein and fiber help to make this smoothie extra thick, creamy and delicious. I recommend using rolled oats or quick oats.

Can I use fresh banana?

Yes, just add 1/4-1/2 cup of ice to get the same creamy consistency and reduce the liquid in this recipe by 1/4 cup. 

How to freeze bananas for smoothie?

Slice the banana into coins then place on a parchment paper or wax paper lined baking sheet to freeze the banana. Once the banana coins are frozen, transfer to a freezer safe bag or container.

Can I make this chocolate smoothie without bananas?

Yes, you can substitute the banana with an additional 1/4 cup of oats or a half of an avocado and add sweetness from maple syrup, honey or dates. Another great alternative would be frozen mango.
