This recipe combines two of our favorite things—coffee and peanut butter. So, it's no surprise that this is one of our favorite go-to morning smoothies. But, we make this one just a little different. Don’t you hate when you crush up ice in a smoothie and it immediately waters it down? Our solution?

We’re showing you how to make coffee ice cubes from your leftover morning coffee (or favorite cold brew concentrate) to blend in your smoothie with no extra water! And, as a bonus, if you want a little extra caffeination, you can throw a couple extra cubes into the blended smoothie and let it slowly melt as you sip.

This recipe also takes advantage of the extra protein found in the chocolate milk to add a rich, creamy addition of protein without being watered down. If you prefer, you can substitute almond milk or your favorite nut milk to create a lighter option. Cacao nibs could be added as well to give the smoothie a crunchy kick without the added sugar of the chocolate milk.

The best part about smoothies is that you can adjust the recipe to be vegan friendly or lower calorie, all based on your mood that day!

What You Need to Make A Peanut Butter Coffee Smoothie Recipe

Bananas. Of course, doesn’t peanut butter go best with bananas? This also helps to give the smoothie its creaminess. If you have overripe bananas, save them by placing them in the freezer and using the frozen banana pieces in the smoothie!

Vital Proteins Collagen Peptides. We’re using this as our protein of choice. It’s a great protein option and benefits hair, skin and nails!

Nuttzo Organic Crunchy Peanut Butter. Nut butter adds to the richness and creaminess of the smoothie and pairs perfectly with the cold brew and bananas.

Chocolate Milk. This is what makes our smoothie a little different than most. Get the chocolate flavor in the form of rich, creamy chocolate milk.

Greek Yogurt. Greek Yogurt is a great way to add additional protein and probiotics into your morning smoothie.

Cold Brew Coffee Ice Cubes. We’ll show you a few different ways to make these ice cubes, but our personal preference is Chameleon Cold Brew Concentrate for that strong coffee flavor.

Cinnamon. Top it off with just a dash of cinnamon for the added health benefits!

Easy Ingredient Swaps

Swap cold brew concentrate for regular coffee. You can create these coffee ice cubes without concentrate. Using leftover morning coffee is a great way to prevent waste in the kitchen and save it for later.

Use the protein powder of your choice. Have a favorite vanilla or chocolate protein powder you love? Use that instead.

Use your favorite nut butter. You can easily exchange the peanut butter in this recipe if you have allergies or simply don’t like the taste. Almond butter or cashew butter will make this recipe just as creamy.

Lower the fat in the smoothie. Two tablespoons of peanut butter can have as much as 16g of fat. While we love adding healthy fats, if you want to reduce the fat content, switch the spoonful of peanut butter for a powdered peanut butter, such as PB2.

Use a different yogurt. Not a fan of the tartness of Greek yogurt? It can be easily substituted for non-dairy options, such as soy or coconut yogurt.

Use cacao powder. If you want the raw taste of cacao powder, you can substitute this for the chocolate milk and use your favorite milk instead!

How to Make Cold Brew Coffee Ice Cubes

Using an ice cube tray, (we love this silicone option!) pour in leftover morning coffee. If using cold brew or coffee concentrate, mix the coffee and water to the correct ratio before pouring into the ice cube trays. Unless, of course, you want a lot of morning caffeine.
Freeze ice cubes until you are ready to use.

How to Make Peanut Butter Chocolate Banana Smoothie

Slice banana into small slices.
In a blender, add banana, Vital Proteins, Nuttzo peanut butter, chocolate milk, and greek yogurt. Blend well.
Add cold brew coffee ice cubes and continue to blend until cubes have fully mixed. Top with a dash of cinnamon and extra cold brew cubes if desired.

Cold Brew Smoothie Variations

Infuse your coffee ice cubes. Want to infuse your coffee ice cubes with even more flavor? Try adding a 1-2 drops of vanilla extract into each cube for that rich flavor. Or, add a splash of heavy cream!

Sneak in veggies. Did you know that you can add frozen cauliflower? It can take the place of traditional ice cubes, but also had a daily serving of vegetables. Even better? It’s absolutely tasteless!

Use cacao powder or cocoa powder. If you prefer a stronger chocolate flavor, you can mix cacao powder into your smoothie. Cacao has a stronger and slightly more bitter taste than cocoa powder, but can expand the chocolate in this recipe, upgrading it to a more distinct recipe.

Use instant espresso. You can skip the coffee ice cubes entirely if you do not have time to make them. Instead, use traditional ice cubes and add 1-2 teaspoons of instant coffee or espresso.

Make it vegetarian. By nature, collagen peptides are made from animal products. To make it vegetarian, simply exchange for a protein powder of your choice and trade the chocolate milk for almond or nut milk.

Make it vegan. All of the ingredients in this recipe can be swapped out for plant-based protein options to make this cold brew smoothie completely vegan-friendly.

Add sweetness with dates. Medjool dates can be a great way to add natural sweetness to a smoothie without added artificial sugar.
