Ingredient notes:
For the full ingredient list and exact measurements refer to the recipe card later in this post.
Jump to the Recipe- Limes - for both the lime zest and lime juice. You can use either key limes or regular limes to make this smoothie.
- Yogurt - full fat plain yogurt is used to help thicken this smoothie. I use full fat coconut yogurt to keep it dairy free but you can use any type of plain yogurt that you prefer including greek yogurt to make it higher in protein.
- Coconut milk - I recommend using full fat coconut milk rather than low fat coconut milk as low fat coconut milk is more watery.
- Maple syrup - to add a little natural sweetness. You could swap this for honeyl.
- Spinach - spinach is used to create the beautiful green colour of this smoothie. And don't worry, if you don't like spinach you can't actually taste it. You can really use as much or as little spinach as you like.
- Collagen peptides - are used to add protein to this smoothie. If you are vegan you can omit the collagen from the recipe, but just note that this will make the recipe lower in protein.
- Hemp hearts (also known as hemp seeds) - hemp hearts are another source of protein and healthy omega fats.
Recipe variations and add ins:
- Feel free to add other seeds such as flax seeds or chia seeds to this smoothie.
- To give this smoothie even more healthy fats and make it even thicker you can add some avocado.
- For dairy free: use a dairy free yogurt.
- To make this smoothie vegan: omit the collagen peptides and use dairy free yogurt.
How to make key lime pie smoothie:
- Step 1: First, place all the ingredients into your high speed blender.
- Step 2: Then blend everything well until smooth.
Top tips:
- Be sure to use a ripe banana to make this smoothie rather than a green banana. You want the banana to be sweet.
- Serving idea: You can serve this smoothie as is, or add some crushed graham crackers to the top of it to make it even more like key lime pie.
