What You'll Need for this Recipe

Frozen Cauliflower makes this smoothie thick and frosty without adding ice, plus it provides a boost of fiber without changing the taste. Don't worry, your kids won't even guess that a vegetable is in there!
Dark Cocoa Powder creates rich, chocolately flavor without adding any sugar or dairy.
Olive Oil adds a dose of healthy fat and extra richness in the smoothie. It definitely makes a difference.

Substitutions & Variations
Milk - I developed this high-fiber smoothie with no yogurt and use almond milk, so it is dairy-free, but you can use whichever type of plant-based or animal milk you prefer. Just note that this will change the macros.
Protein Powder - Neutral-tasting protein powder or collagen peptide powder works best here so that the flavor of the other ingredients can come through. Or you can reduce your ingredient list by using a dark chocolate protein powder.
Sweetener - This high fiber chocolate smoothie turns out just as well with other sweeteners. Try Medjool dates, honey, agave nectar, or your favorite zero-sugar option like stevia or monk fruit!
Vegan - Use plant-based milk and vegan protein powder to make this recipe vegan-friendly.

Is this recipe good for people with PCOS?
The magic of this fiber-filled smoothie is how balanced it is. The ingredients help support stable blood sugar, fight insulin resistance, and feed happy hormones. Here's how:
Cinnamon has been shown to lower fasting glucose and improve insulin sensitivity. (NIH)
Chia seeds are nutrient-dense and particularly high in fiber, omega-3 fatty acids, minerals, and antioxidants (NIH). You could also try basil seeds--just be sure to soak them first.
Fat, fiber, and protein in combination help reduce glucose spikes, increase fullness, and improve androgen levels and inflammatory markers in PCOS. (NIH)
Bonus: This smoothie can easily be tweaked into a great seed-cycling recipe to support balance in every phase of the cycle! Add pumpkin seeds and swap the chia for flaxmeal during the menstrual and follicular phases, or add in sunflower and sesame seeds during the ovulatory and luteal phases.

I made this after my workout yesterday and it was delicious! I felt like I was drinking a milkshake, but better because it was healthy. It kept me nice and full until dinner time! Def keeping this recipe in the rotation.

I started exercising in earnest about 6 months ago so I'm really concerned with getting enough protein. This is shake was a wonderful snack for me on busy days - I substituted cardamom for the cinnamon and added grape seed instead of olive oil. Terrific!
