Place the cocoa, cinnamon and sugar into a bowl and mix them together completely with a fork. If your cocoa is lumpy, break those up as much as you can with the fork and mix the lumps in.

Add one tablespoon of milk to the center of the cocoa mixture. With the fork, mix it in, making a paste of cocoa.

Making a paste every time until it's fully diluted, add the milk by tablespoon increments.

Add the remaining milk and vanilla and mix thoroughly.

Place in the microwave in a microwave-safe bowl for 3 minutes.

While that is heating, place the corn syrup in a saucer or bowl bigger than the mouth of your mug.

Place the sprinkles in a similar bowl.

Dip the mouth of the mugs into the corn syrup, then into the sprinkles to rim the edges well.

When the hot cocoa is done in the microwave, remove it carefully and pour half in each mug.

Top with ice cream cone, 2 pink/white marshmallows on either side of the ice cream cone and more marshmallows.

Drizzle strawberry syrup over the top and serve!
