Add the ice cubes to your blender cup, then add the milk and remaining ingredients.
Blend for about 30 seconds to a minute, or until smooth and creamy, ensuring the marshmallows are well incorporated.
Pour the shake into a tall glass or shaker (or drink right from the blender cup!).
Garnish with additional graham cracker crumbs, chocolate chips, or a toasted marshmallow for that authentic campfire flavor (optional).
Enjoy your S'mores Protein Shake!
Notes
Ingredient Substitutions
Try different milk options, like Fairlife dairy milk or your preferred milk alternative.
Experiment with different flavored protein powders for a unique twist. Chocolate whey protein would be great here, as would cinnamon flavored protein powder.
Use sugar-free chocolate syrup instead of chocolate chips.
Replace keto marshmallows with vegan marshmallows for a cruelty-free option.
Recipe Variations
Turn this shake into frozen protein bites by freezing the mixture in a silicone mold.
Create Peanut Butter S'mores Smoothies by adding a tablespoon of peanut butter to the shake.
Add ¼ teaspoon alcohol-free vanilla extract to enhance the flavor further.
Turn this into ice cream with 30 g protein by adding the shake to an ice cream maker or Ninja Creami.
Storage InfoThis protein dessert shake is best enjoyed fresh. However, you can store any leftovers in the refrigerator for up to 24 hours.
