Get a very ripe banana, peel it, and freeze it overnight. It will come out just as yummy with an unfrozen banana too, but i prefer mine frozen. Add your strawberries, blueberries, chai soy milk and spices. If you don't have pumpkin pie spice, basically all it is is allspice, nutmeg, cinnamon, and ginger so you can add a little bit of each. I usually just put in a quick shake of cinnamon and a quick shake of pumpkin pie spice. If it's too thick you can add more chai soy so it will blend better. You can also use fresh strawberries and blueberries instead of frozen but you may need to sweeten it a little. It's up to you! And that's it! Super simple, and it's got such a nice flavour!
