    As a Certified Nutrition Coach, I can tell you that you don't need protein powder to reap the benefits. It's simply that it makes life as a busy mom easier because you can grab something and dash out the door.

    If you’re an avid gym-goer, this key lime pie smoothie makes an indulgent and replenishing post-workout shake. Not only does the flavor give you a burst of energy, but it gives your muscles the recovery tools they need... and all in smoothie form! Learn more about adding protein to smoothies!

     

    The Best Things About This Protein Shake

    • Made in just five minutes
    • 31 grams of protein so perfect for breakfast
    • Great for on-the-go days
    • Refreshing and energizing flavor (it tastes like key lime pie!)
    • Indulgent (just like the dessert!)

    Ingredients You'll Need

    One of the awesome things about this key lime pie smoothie is that you can make it as indulgent (or not!) as you like).

    Fresh lime juice: typically a key lime pie will use key lime juice for its flavor. These limes are smaller than normal and normally a bit more yellow. Whether you choose to use key lime juice is up to you, regular lime juice will work just as well. This also applies for something like a piña colada smoothie too!

    Coconut yogurt: this helps keep the key lime pie smoothie super creamy. Any dairy-free yogurt will work but any Greek Yogurt will result in a very thick texture and you may need more liquid.

    Vegan protein powder: each protein powder will result in a slightly different consistency and flavor. Pea protein will create a thicker texture and non-pea protein will be thinner.

    Spinach: get that lovely green flavor and a dose of nutrients! Frozen spinach leaves blend best into the key lime smoothie as they tend to crystalize.

    Gluten-free graham crackers: make the smoothie as indulgent and dessert-like as you wish by adding these in or using something lighter like keto graham crackers with almond flour crust.

    Date: adding just a hint of sweetness without added sugar.

    How To Make A Key Lime Pie Smoothie

    1. Juice a lime into a high-powered blender.
    2. Add in the remaining ingredients.
    3. Process until smooth.
    4. Portion the key lime pie smoothie into a jar.
    5. Topped with graham cracker crumbs and whole30 whipped cream if desired.

    Choosing A Protien Powder For The Key Lime Smoothie

    This recipe has been made with a variety of protein powders. In fact, it was originally made with whey protein.

    When choosing a protein powder make sure to read the ingredients and opt for one that suits your dietary needs and has minimal ingredients.

    I personally use Genuine Health for my protein powder. Not only do they have a few healthy additions to their protein powders (it’s fermented, they add healthy fats etc) but it also doesn’t contain any seed oils which have a multitude of health risks but are common in purchased products.

    Another great option is Botanica protein powder. It is made solely from whole-food ingredients.

    Keep in mind that the protein powder you choose will affect the flavor and the texture of the key lime pie smoothie. Vegan protein powders are made with different protein blends and absorb liquid uniquely.

    Learn more about how to choose a protein powder for your goals.

     

     

    Important Teaching Tips

    If you want to boost the protein of the smoothie and don’t follow a vegan diet, use cottage cheese in place of coconut yogurt.

    Fresh lime juice will have the best flavor for the smoothie.

    The nutritional values are calculated with one store-bought graham cracker added to the smoothie. However, if you’re looking to scale back carbohydrates, omit that.

    The graham crackers you choose as well as the protein powder will affect both the flavor and the texture of this smoothie. You may need to add more water.

    You can either buy graham crackers to have on hand or make your own keto graham crackers.

    Frequently Asked Questions About The Key Lime Pie Smoothie

    Is lime good in smoothies?

    Lime is an easy add-in to smoothies and gives them a burst of flavor. Plus, many people are energized by lime. Thus, it makes a great ingredient to refresh post-workout and give you a little pep in your step.

    Can you make the key lime pie smoothie ahead of time?

    Though you can make the smoothie ahead of time it will lose its creamy consistency while stored. It tastes best fresh.

    What do you top the smoothie with?

    Depending on your personal goals and dietary restrictions, you can top the key lime pie smoothie with coconut whipped cream, graham cracker crumbs, and lime zest.

    Do I need to use key lime juice?

    Key limes tend t be smaller than normal and have a slightly stronger flavor. However, they're not necessary. Regular limes + the zest of the lime tastes just as delicious!
