Although ice cream is lean, I make it not only in the Post. Very tasty and flavorful - it is very popular with my children. It is prepared with only 2 ingredients, you can do without special molds for this dessert.
You need a ripe banana. Peel it and cut it into pieces.
Mash with a fork, add vanilla and cinnamon.
Add the cocoa.
Stir well with a fork.
Beat with a mixer.
Put in molds. I put them in small jars. It is very convenient to give them to children. Put in the freezer for 5-6 hours. For a more uniform texture, you can punch the blender again an hour after the start of freezing.
