Chocolate banana pudding

In a small bowl, use a fork to mash the banana to a smooth pulp.
In a medium bowl, use a fork to whisk cocoa powder, cornstarch, cinnamon, and salt.
In a second medium bowl, lightly beat eggs. Whisk eggs into the cocoa mixture to make a smooth paste. Whisk out any pockets of flour and cocoa completely.
In a medium pot over medium heat, heat milk and honey. Bring to a simmer.
Pour a small amount of the hot milk mixture over the egg mixture. Whisk constantly until smooth. Continue adding milk, a little at a time, until about half the milk mixture is used.
Add egg mixture to pot with remaining milk. Cook over low heat, stirring constantly with a rubber spatula until it just begins to bubble and thicken. Remove from heat.
Whisk in mashed banana right away until fully combined.
Pour warm pudding into 6 small cups. Eat warm, or refrigerate until set, about 2 hours.
