Start your morning with a whole new kinda energy from a coffee smoothie. All the taste and sweetness of those fancy iced drinks you love without the artificial sugars and weird ingredients.

Healthy Coffee Smoothie using protein and caffeine

Coffee in moderation is a great way to boost your morning energy levels, but a plain cup of joe isn’t enough to carry you through until lunch. With this coffee smoothie, you get all the benefits of coffee along with the perfect pairing of good-for-you, nutrient-packed ingredients.

Health benefits in coffee banana smoothie

  • Frozen cauliflower – Yes, you read that right! Frozen cauliflower thickens this smoothie while adding a ton of health benefits (it’s a cruciferous veggie). Trust us, you won’t even notice it’s there.
  • Protein powder – A scoop of plant-based protein powder helps you feel full longer and prevents loss of lean muscle mass. It’s also a great way to get in your daily protein requirement.
  • Banana – Adds natural sweetness and creaminess to the smoothie, and it’s a great source of potassium and vitamin B6.
  • Dates – Naturally sweetens the smoothie and adds a little fiber.
  • Coffee – Caffeine in moderation is not a bad thing. It can improve energy levels, boost your metabolic rate and may help protect against Alzheimer’s disease.
  • Oat Milk – This non-dairy alternative contains beta-glucan, which has been linked to improved gut health. Make sure to check out the Best Oat Milk Brands of 2020 before hitting the store. You can also use cashew milk and almond milk if you prefer.
  • Cacao Powder – An antioxidant-rich powder that adds a chocolate-y flavor and pairs so well with coffee. This is where we got the mocha part of the name…. and will never ever take it back. It’s soooo good!

How to make a coffee smoothie

Now, this isn’t any coffee smoothie— this is a breakfast smoothie that’ll keep you full and energized (and satisfy your coffee craving). You will need…

  • cauliflower
  • banana
  • cacao
  • vanilla extract
  • oat milk (or other non-dairy milk)
  • dates
  • brewed coffee (or cold brew)

It’s important to make sure the coffee is cold for this recipe. Cool it in the fridge before adding to the blender (or put a few ice cubes in it). When ready, place all of the ingredients in a high-powered blender and blend until smooth and creamy.

What kind of coffee to use

There are a few different methods for making coffee for your smoothie:

If using a drip coffee maker, brew a pot of coffee and reserve a few cups for making smoothies. Cool the coffee to room temperature before using in the smoothie. Pour any extra coffee in a mason jar or glass container and store in it the fridge for up to 5 days. Or pour the room temperature coffee into an ice cube tray and freeze for future smoothies.

As for beans, I always recommend supporting your local coffee roaster. For me, that’s Mountaineer Coffee Roaster in our central Florida small town.

You can use instant coffee if that’s what you’ve got on hand. Simply make a cup of instant coffee according to the directions on the package. For stronger coffee flavor, add an extra serving of instant coffee granules. Let the coffee cool to room temperature before using it in a smoothie. You can also add instant coffee granules directly to your smoothie. Add 1-2 tsp of instant coffee to your blender along with the rest of the ingredients.

If using store-bought cold brew coffee, follow the instructions on the bottle to make ¾ cup coffee. It’s usually a 1:4 ratio of coffee to water.

Healthy Coffee Alternatives

If you’re trying to be more mindful of what you put in your coffee (or even drinking caffeine in general), we’ve been there! Here’s a few tasty options that I think you might like to play with:

I went from exhausted mama to running across the Grand Canyon, riding & hiking to the top of the tallest waterfall in North America with my kids. How? I fell in love with the smoothies and plant-based meals you can find on my blog.

    I didn’t have frozen cauliflower so substitute me frozen broccoli – still very tasty!

    1. Hey Lisa,

      Great question. The only ingredient that might not have a similar consistency after a long sit in the fridge would be the frozen cauliflower. I say, give it a try! With all these delicious ingredients, I can’t imagine this smoothie ever tasting bad.

  2. Hiya love your smoothies just not a fan of bananas is there anything I can substitute it with was thinking avocado but would need something to sweeten it would u just add more dates if so how many I followed what one of your followers said and put in chia seeds am also amazed at the cauliflower didn’t notice it at all and I don’t eat any veg so this will def be a plus for me.keep up the great work

    1. You can def try adding in another date or two to sweeten it up. Another option is to add a little maple syrup. So glad you are enjoying the smoothies. It’s amazing how you can sneak in some veggies and make them taste yummy!

    This is an awesome smoothie. I am breaking the habit of drinking “hot mochas”. This is much-needed, healthier and more satisfying replacement!

    This is so good! Who needs Starbucks when you can have this! You can’t even tell there is cauliflower in it.

  5. This looks really good, can’t wait to give it a try tomorrow morning! I’m curious where the bulk of the 33g of sugar comes from? Is it the protein powder?
