The Most Important Meal of the Day

Are you a breakfast fan? I am! Actually, if I’m being honest, most nights I go to bed excited to wake up and eat in the morning. With recipes like Chocolate Ganache Overnight Oats, Gluten-Free Vegan Cinnamon Rolls, and Churro Waffles with “Mexican Hot Chocolate” Sauce, how could I not be excited to wake up?! I love mornings when I can take the time to make a delicious meal and enjoy a hot cup of coffee. 

That being said, with 3 littles running around, a full-time job, daily tasks, and more, my schedule doesn’t always allow me to make a full meal in the morning. However, they don’t call breakfast the most important meal of the day for nothing, and I know if I skip it altogether I will not be setting myself (or anyone else who I come into contact with) for a good day. So, on those mornings when I need something that is fast but is still full of nutrients and filling, I opt for this Cold Brew Coffee Smoothie! 

Not only is it delicious, but it’s also loaded with fresh fruit and vegetables, healthy fats, protein, and most importantly, caffeine! Basically, it’s got everything you could need and more to feel awake, energized, and satisfied all morning long. Even better, you can make it ahead of time so all you have to do is grab and go, but we’ll get into that later! Keep reading to find everything you’ll need to know to make this coffee smoothie recipe. 

Ingredients for a Healthy Coffee Smoothie

For this coffee smoothie, I used 7 ingredients that are full of nutrients and taste amazing! However, feel free to experiment with your own combinations and add-ins to make this smoothie recipe your own. To get you started, I used: 

  • Coffee – Make sure you cool your coffee before making a smoothie! If you don’t, it will explode.
  • Milk – I used soy milk, but you can use any milk you like best. However, I recommend sticking with a plain milk flavor to avoid overpowering the rest of the ingredients.
  • Avocado – Avocado helps to create a thick, creamy smoothie similar to what a banana with achieve without adding extra sugar. *if you use a protein powder that isn’t sweet, swap the avocado for a banana!
  • Nut/Seed Butter – Any nut or seed butter you like best can be used for this recipe. I recommend a neutral-tasting option such as cashew butter! (use code: kellyk to save a few bucks on Georgia Grinders, if you want!)
  • Cauliflower – I promise you can’t taste the cauliflower! When frozen, it helps create a thicker texture and adds vitamins, nutrients, and fiber to keep you full!
  • Cocoa Powder – Make sure you use unsweetened cocoa powder to add antioxidants and a rich, chocolatey taste to your coffee smoothie.
  • Protein Powder – I like to use Vanilla protein powder from Nuzest (code: thekellykathleen), but any other protein you have on hand will work, too! Feel free to use different flavors such as chocolate or a coffee flavor, if you prefer. 

Optional Add Ins for Even More Nutrition

As if this coffee smoothie recipe wasn’t already loaded with good-for-you ingredients, you can easily add more! Some of my favorites include: 

Flaxseeds: A great way to add fiber, flaxseeds can be added to smoothies without altering the taste. I wouldn’t use more than a tablespoon, though! Otherwise, the texture might become a little grainy.

Chia Seeds: Tasteless, a tablespoon of chia seeds can help provide healthy fats and fiber to your diet. 

Oats: To thicken your smoothie and make it a little more hearty, add less than ½ cup of oats to your smoothie. Just make sure they aren’t steel cut oats as they won’t blend! 

Avocado: Believe it or not, adding avocado to your smoothies can help create a super creamy texture you’ll love. Plus, it’s full of healthy fats to keep you satisfied! 


How to Make this Cold Brew Coffee Smoothie

The best part about this recipe is how easily and quickly it comes together! Essentially, in one step, you’ll be on your way to a delicious meal. All you have to do is add the ingredients to a high-speed blender, and blend until it is smooth. 

Tips for the Best Consistency

Take a look at my top tips to get the best taste and texture out of your smoothie! 

Scrape the Sides. While blending, stop once or twice, and scrape the mixture from the sides of the blender to ensure that everything is well-blended. 

Add Milk. If your smoothie is too thick, add a splash or two of milk to help thin it out. 

Add Powders. If your coffee smoothie turns out to be too runny for your liking, add an extra tablespoon or two of cocoa powder or protein powder, and blend the ingredients again. 

3 Make-Ahead Options

For easy mornings, try making this coffee smoothie ahead of time using one of my 3 meal prep methods below! 

Ice Cube Tray Method: Blend your smoothie as usual. Then, add it to an ice cube tray, and pop it in the freezer. When you’re ready to eat (drink), place it in the fridge for an hour, and enjoy! Or, place the cubes in a blender, add a dash of milk or more coffee, and blend until smooth.

Mason Jar Method: Blend your smoothie until the desired consistency is reached, pour it in a mason jar, and store it in the fridge for up to 3 hours or in the freezer for up to 3 months

Smoothie Pack: Add all of the ingredients, except for the coffee to a sealable bag, and place it in the freezer for up to 3 months. Then, add them to the blender, pour the coffee over, and blend to enjoy! Or, blend your smoothie, and store it in a sealable bag in the freezer instead. To drink, let it thaw in the fridge, pour it into a glass, and sip away! 

Can I Use Decaf Coffee? 

Sure! If you are avoiding caffeine, use decaf coffee instead, and follow the instructions as they are written below.

      Whatever your stomach can handle is the best route. The raw frozen cauliflower doesn’t bother me but steaming and freezing is a great option too!
