Start by stirring egg yolks, milk, and sugar in a pot on medium heat, until thickens to the consistency of heavy cream
Remove from heat and mix in cocoa powder! Chill for 30 min in the freezer :)
Remove from freezer and mix in heavy cream and vanilla, chill again for about 30 min and then throw everything in the ice cream maker!
Let the ice cream maker spin for about 30 min. Then add your mix ins! I used white and dark chocolate chips!
Chill in the freezer for as long as you like, then serve. I drizzled mine with chocolate syrup!!:)
