If you serve this to your kids for breakfast they may think you have lost your marbles and have given up on healthy food! This is an outstanding breakfast shake and provides highly nutritious, blood sugar balancing and brain-boosting ingredients to keep your child focused and full all the way to lunchtime. This shake is also a superb pick-me-up after a long school day. The best part is that it will take all of 60 seconds to whiz up in a blender. I have used cashew butter from Biona in this recipe but you can use any nut butter (peanuts are not strictly nuts and are prone to aflatoxin so they are best avoided). If you have a nut allergy then pumpkin butter or tahini (or half of each) works equally well. You can use water instead of a plant-based milk but I like the creaminess that comes from almond or homemade cashew milk. Please see our Ultimate Guide to the Best Dairy-Free Milk for inspiration. Raw Organic Cacao is the highest plant-based source of iron available, but given this is a non-animal-based iron (also known as non-heme) it needs some vitamin C for the iron to get absorbed by our bodies. For this reason, I have added a kiwi fruit to the recipe but you can replace it with a large clementine or medium-sized orange or 1/2 a cup of peeled papaya and in the summer a handful of strawberries will do the job very nicely. If you want a sweeter flavour then add in 2 to 4 large soft medjool dates to give a lovely caramel flavour and keep even the sweetest tooth blissfully happy.
