In a medium-sized bowl, whisk the cocoa powder, sugar, cornstarch, and salt together until the dry ingredients are clump-free.
Whisk half of the milk into the dry ingredients. Whisk until smooth. Whisk in the remaining milk.
Heat the mixture over medium heat until thickened. Stir with a spatula paying careful attention to the sides and bottom so the mixture does not burn. Once it looks like a chocolate sauce (this will happen quickly). Remove from heat and stir in the vanilla.
Allow mixture to cool for 5-7 minutes. The mixture will thicken it as it cools. Pour the mixture into poplicle molds and add popsicle sticks. Freeze for 8 hours.
Remove the Fudge Pop from the mold and serve.
Notes
Servings vary according to the size of the container you use.*Sifting the cocoa powder first makes removing the clumps from the dry ingredients much easier.
