medium-sized bananas • vanilla extract • large spoonful of sweetened peanut butter (I chose Jiff because it’s saltier than other sweetened peanut butters, balancing the flavors.) • Chocolate syrup (to your preference) • chunks of ice • Milk (your choice of milk and desired amount. The less milk the thicker the shake will be which is what I recommend.) • Crushed cashew nuts (Desired amount. Optional)
