Why You’ll Love This Peanut Butter Avocado Smoothie Recipe

Since this smoothie highlights avocados, it’s a more savory smoothie than most fruit smoothies.  

Even if you’re not an avocado fan, the taste is so muted because of the peanut butter and banana flavors that you won’t even notice it! 

Even if you are an avocado fan, you may be wondering: avocado and peanut butter…do those two things even go together?! To be honest, I wouldn’t have thought so but seriously, it’s so good! You just need to try it, I swear!

This avocado peanut butter smoothie is also a great way to get a lot of nutrients in because it’s packed with great nutrition. It has a high amount of fat, particularly healthy monounsaturated fats that can help to improve your heart health and reduce inflammation. 

It’s also loaded with fiber, with one serving of this peanut butter avocado smoothie giving you 13g of fiber. The Institute of Medicine (IOM) recommends 25g of fiber per day for adult women under 50 years old and 38g of fiber per day for adult men under 50 years old (1).

Now let’s get into how you make this delicious smoothie!  

Ingredients You’ll Need

• Avocado – I used frozen avocado chunks to make a thicker smoothie and it also replaced the need for ice. You can certainly use fresh ripe avocado though, you may just need to add a few ice cubes to get the desired consistency and temperature you want.

• Peanut Butter – a natural peanut butter that’s smooth or chunky is perfect for this smoothie. You could also substitute another nut butter like almond or cashew butter if you’d prefer.

• Frozen Banana – I stuck my banana in the freezer for a little while to make it more conducive for a smoothie but you could also use a fresh banana too. Fruit, especially a ripe banana, adds natural sweetness to cover up the avocado taste. Sweet taste without the added sugar? Count me in!

• Spinach – spinach is a great leafy green addition that packs in a lot of nutrients without altering the smoothie taste. Spinach is also the secret ingredient that gives this green smoothie its bright and gorgeous color.

• Almond Milk – unsweetened almond milk is my liquid of choice for smoothies…it’s just so light and refreshing. You can use any type of traditional milk or plant based milk that you enjoy or have on hand though.

• Protein Powder – I added just one scoop of unflavored collagen peptides to this to increase the protein content to make it a more filling and balanced meal. You can use any type of protein powder you enjoy, or you could omit this altogether too!

• Cinnamon – this is mainly for flavor but cinnamon is actually a great addition to reduce blood sugar levels (2, 3)

• Monk Fruit Sweetener – this is a natural sweetener taken from monk fruit. This monk fruit sweetener is my favorite one. If you don’t typically use monk fruit sweetener, you could substitute honey or maple syrup instead. 

How To Make It

One of the reasons I love smoothies so much is because they’re ridiculously easy to make. You really don’t need any significant cooking skills to make them either. 

To make this smoothie, you’ll simply add all of your ingredients into a high-speed blender. I generally add all liquid ingredients to the bottom of the blender and more solid ingredients towards the top. 

Then blend the ingredients on high-speed for 20-30 seconds or until smooth. 

Pour into a tall glass and enjoy immediately!
