Chocolate Coffee Frappe

Coffee jelly made with agar powder and rice flour-- no gelatin called for. This frappe is perfect for those hot summer days ♪ A tip for added sweetness-- use overripe bananas that have brown sugar spots. The natural sweetness of the bananas adds to the taste and keeps the processed sugar content low. If you happen to have bananas that have turned completely black, stick them into the freezer for later use in this frappe recipe!
