Nourish Me Free. Chocolate Beetroot Brownie Cake. What is not to love about a soft and spongy brownie or cake! This one is made even better by being healthy with beetroot and carob, and is AIP compliant. It has the perfect balance of flavours so you feel good while eating it, and is so light in texture. Yummy! Super light, spongy and semi sweet, this is the perfect brownie or cake in my mind with the benefit of being vegetable based. It makes a quick and nutritious AIP snack or treat.
