Why This Coffee Smoothie Recipe Works

Classic combo with a twist. Sweet bananas paired with creamy peanut butter is a classic combo that I can’t get enough of. But, pair those two with iced coffee and a scoop of protein powder, and you’ve got yourself a new favorite breakfast drink. Bring it in a to-go mug to kickstart your day in the best way possible! 

Coffee lover’s dream breakfast. I always thought that nothing would beat my original recipe for a Coffee Smoothie—until I put peanut butter in it. o.m.g. 😱 Friends, this little addition made a huge difference. The following morning, I added a scoop of chocolate protein powder, too, and things got even better. My protein smoothie turned into a powerhouse of antioxidants, vitamins, and fiber, but best of all, it had a delicious coffee flavor!

Household favorite. Smoothies are a breakfast favorite around here. Our go-to is the one and only Banana, Kiwi, and Kale Smoothie – SO amazing! – or a bowl of this Rainbow Protein Smoothie. We all got used to just throwing a bunch of good-for-you ingredients in the Blendtec, and with just a whirl, our breakfast is done.

The Ingredients

You can make this fantastic coffee smoothie with just five simple ingredients! This recipe combines brewed coffee with the creaminess of natural ingredients to create a smoothie that’s not just delicious but also a healthy start to your day.

  • Brewed Coffee: Make a cup of your favorite coffee and pour it into an ice tray to freeze overnight.
  • Large Banana: Adds natural sweetness and adds to the smoothie’s thick and smooth texture.
  • Smooth Natural Peanut Butter: Contributes a nutty flavor and protein boost. Almond butter, or any other nut butter, is a good substitute.
  • Chocolate Protein Powder: Provides a chocolate flavor while increasing the protein content. For a different flavor, you could use vanilla or any other flavored protein powder.
  • Almond Milk: You could also use regular milk, coconut milk, or soy milk.

How To Make a Coffee Protein Smoothie

Making coffee smoothies is so, so simple. Just freeze your coffee overnight, and in less than a minute of blending the next day, you’ll enjoy an energizing smoothie.

  1. Brew and Freeze. Before going to sleep, start by brewing a cup of coffee. Do not drink it. 🙂 Instead, please pour it into an ice tray and place the tray in your freezer.
  2. Combine and Blend. The following morning, pour out the coffee ice cubes into a blender. Add a banana to the blender, as well as the peanut butter, protein powder, and milk. Blend until the mixture is well combined and thickened. 
  3. Consistency. If the smoothie is too thick for your liking, add a bit more milk, about a couple of tablespoons at a time, and blend until combined. If it’s too thin, add ice cubes and mix until combined.
  4. Serve. Pour into glasses and serve. 

Proper Storage

Smoothies are the perfect meal prep – they keep in the fridge for up to 3 days – and are an easy way to keep our first meal of the day on track. Store smoothies in an airtight glass container secured with a lid. Refrigerate for 2 to 3 days. Smoothies can also be frozen into popsicle molds – they are perfect on a hot summer day.
