3 1/2 cups milk (I used 2%)
1/2 cup heavy cream
1/2 cup baking cocoa
1/3 + 1 tablespoon sugar
1 tsp vanilla
1/2 cup semi sweet chocolate chips
Whisk together the milk, cream, sugar and cocoa powder in a medium saucepan. Continue whisking and heat over medium heat until very hot (but not boiling).
Beat the eggs in a medium bowl. Slowly pour about 1/2 of the milk mixture into the eggs, whisking to combine. Pour the egg/milk mixture back into the saucepan and combine well with the rest of the milk. Heat over medium heat until slightly thickened. Don't let it boil.
Remove from the heat and add the salt, vanilla and chocolate chips. Whisk until the chocolate chips are melted. Let cool and pour into popsicle molds.
