Take an empty jar. Now, add 1-2 tablespoons of your desired coffee flavor into the jar. After that, add 1 and a half cups of water into the jar.
Give it a good stir. Cover the jar and leave it in the refrigerator for 5 hours or overnight. Once the coffee is ready, after the estimated time, let's get set to make the banana.
Now, take out your bananas, about 5 of the ripe ones, slice them into bits, and pour them into the blender. After that, add 1 cup of milk to the blender. Now, add 1/2 cup of coconut milk.
Next, add 2 tablespoons of Icing sugar (optional). 1/2 Tablespoon of vanilla extract would go in next. Now, add 1-2 tablespoons of ground almonds. Cover the lid of the blender and blend until smooth.
Now, strain your coffee into two big mugs equally (as indicated in the video below). Remember to add coffee mixture to your taste, add less if you don't like strong flavor. Once that is done, add your banana milk.
Sprinkle some ground almonds and coffee powder on top to garnish. You can also add a banana slice to the glass tip. Your smoothie is ready. You can pour them out in jars
