To make the drink, you need a juicer, any kind will do as long as it can produce juice. Cut the banana into pieces and put them into the juicer
Add a box of yogurt. The reason why I like making drinks is that it is not as serious as baking. The amount of ingredients used is very casual and does not need to be very precise.
Then pour in the milk, just pure milk. Bananas are very sweet, so there is no need to use sweetened milk, as it will be too sweet
Next, just start the juicer, crush and mix all the ingredients inside to make a fine juice.
