    My Banana Smoothie with coffee, peanut butter and chia seeds is the best way to fuel and caffeinate your mornings in one sip.

    Close up of two glasses of coffee banana smoothies.

    Smoothies are such a convenient breakfast option because they only take 5 minutes and you can sip on them during your commute, at your desk, in meetings, etc. I always use my perfect fruit smoothie guide, but lately I've been obsessed with making banana smoothies with coffee. It's the best way to get in caffeine incorporated with my breakfast, helping it absorb slower into the bloodstream, and adds a delicious coffee flavour.

    Caffeine, protein, fiber and healthy fats all in one yummy smoothie: what more could you ask for at breakfast?

    Why This Recipe Is Dietitian Approved

    1. Balanced. If you ever find yourself hungry 1 hour after drinking a smoothie, it's probably because it was just fruit and milk. This smoothie is packed with protein, fibre and healthy fats to keep you full and energized.
    2. Easy and fast. It only takes 5 minutes to whip up this smoothie.
    3. Caffeine + food. Do you ever feel sick or jittery having caffeine on an empty stomach? This coffee banana smoothie is a great option, because pairing the caffeine with other nutrients slows its absorption.

    Ingredients

    Ingredients including cold brew, collagen, banana, ice, chia seed, peanut butter, milk, greek yogurt, dates and vanilla.

    Cold brew coffee. I use the Stok cold brew coffee that comes in a jug, however any brewed strong coffee will work great. I typically recommend ensuring it is cold before adding to the smoothie (so the ice doesn't melt). 

    Milk. Any milk of choice will work great. I typically use dairy milk but the choice is yours.

    Greek yogurt. For protein and to add a creamy texture. I like using 2% plain greek yogurt to ensure you are getting some fat without additional added sugar. 

    Banana. You will need one whole banana for this recipe. The banana helps create a thick and creamy consistency, while also adding sweetness and additional fiber. You can use a fresh or frozen banana.

    Protein powder. Any protein powder or collagen will work great. This is a key ingredient in adding some protein to power you through your morning, so you're not immediately hungry. In the photo above I used Vital Protein collagen peptides, however protein powder will also work.

    Peanut butter. For healthy fats! I usually look for peanut butter that only contains 1 ingredient: roasted peanuts (and sometimes salt).

    Cinnamon. I love adding a pinch of cinnamon to my coffee in the morning, so this adds the perfect amount of coziness!

    Chia seeds. For fiber! 1 tablespoon of chia seed has 4g of fiber and helps thicken the smoothie.

    Ice. This is optional, but helps thicken the smoothie and keep it cold.

    Dates. Nature's candy! I love it because it adds a rich caramel tasting sweetness to this banana coffee smoothie.

    Vanilla extract. For flavour!

    The complete ingredient list with measurements can be found in the recipe card below. 

    Instructions

     Blending baana smoothie with coffee.
    1. To a blender add cold brew coffee, greek yogurt, banana, collagen or protein powder, peanut butter, chia seeds, cinnamon, ice, one date and vanilla extract. Blend until smooth.

    1. Pour into a glass and enjoy!

    Substitutions and Variations

    To make gluten-free: this recipe is naturally gluten-free.

    To make dairy-free: substitute the greek yogurt with any thick non-dairy yogurt of choice and substitute the milk with a non-dairy option. Ensure your protein powder is dairy-free too.

    To make nut-free: swap the peanut butter for sunflower butter or omit.

    Equipment

    • High powered blender

    Storage

    This banana coffee smoothie tastes best fresh.

    Top Tips for Success

    If you are looking for the CREAMIEST, thickest smoothie, I recommend using a frozen banana. This will create a thicker, more ice cream-like consistency.

    As with any smoothie it is very easy to customize this to meet your taste preferences. Looking for a sweeter flavour? Add an additional date or a little maple syrup. Looking for a strong coffee flavour? Substitute the milk with additional coffee!

    Frequently Asked Questions

    Is this smoothie a meal or snack?

    This banana coffee smoothie has lots of protein, fiber and healthy fats because it's meant to be a meal-sized smoothie to keep you full for hours. If you would like to try it as a snack, you could split it into two snack sized smoothies.

    What kind of coffee can I used in this coffee smoothie?

    I recommend using cold brew or brewed coffee (cooled). I don't recommend using pure espresso because it may be too strong.
