Creamy, Indulgent Peanut Butter Banana Smoothie…

This smoothie is naturally sweet and creamy, thanks to the frozen banana, with a hint of yummy vanilla flavor. Throw a bit of peanut butter into the mix, and you get an ultra-creamy texture and the perfect balance of salty and sweet!

Of course, you can use any nut butter that you prefer, or substitute with sunflower seed butter to transform this peanut butter banana smoothie into a nut-free smoothie.

Finally, you can maximize the thick, creamy texture and stick-to-the-roof-of-your-mouth goodness by blending in some steamed cauliflower! (It won’t actually stick to the roof of your mouth, but it’s THAT luscious and decadent.)

…With a Serving of Cauliflower?!

Believe it or not, cauliflower is one of the most versatile veggies, and it can be used in all sorts of amazing ways. The taste of cauliflower is invisible in this peanut butter banana smoothie, but you still get to enjoy its incredible nutritional benefits!

Cauliflower is a great source of dietary fiber and essential vitamins, like immune-boosting vitamin C and bone-strengthening vitamin K. Combined with a frozen banana, you get almost your entire days’ worth of vitamin C in this peanut butter banana smoothie!

Plus, cauliflower is one of the best plant-based sources of choline, which can boost our memory and brain function. Though most people associate choline with animal products like eggs, liver, and salmon, cauliflower is a great plant-based option!

The Subtly Sneaky Superfood

Most impressively, cauliflower turns this peanut butter banana smoothie into a disease-fighting superstar. Like kale and broccoli, cauliflower is a cruciferous vegetable, rich in antioxidants and anti-inflammatory compounds.

It contains a few powerful anti-cancer compounds, like glucosinolates and isothiocyanates—both of which have demonstrated the ability to actually slow the growth of some cancers in research studies! Fighting cancer with a smoothie?? It doesn’t get much peanut BETTER than this!
