Take banana slices, cocoa powder and sugar in a blender/mixer. Grind together to fine puree. Include milk and pulse it once again.
Next adjust consistency by adding some water and then pour in to popsicle mould. Freeze it for at least 8 hours or overnight.
After the freezing time, take out the popsicle mould and hold under running water. Let it be outside for 5 minutes. Then slowly pull out the popsicle from mould and enjoy. Kids favourite chocolate popsicle is the actual summer delight.
Notes
Adjust the sugar depending upon the sweetness of banana.
Do not overuse the cocoa powder as it may turn the popsicle bitter.
As we are using milk here the consistency will be thick. So include water to get it in pouring consistency.
