Homemade Fudgesicles

1 cup whole milk, room temperature 1/3 cup granulated sugar 2 tablespoons unsweetened cocoa powder, sifted 1 tablespoon cornstarch 1/8 teaspoon salt (preferably kosher) 1 ounce semisweet chocolate, chopped 1/2 teaspoon vanilla extract

In a large saucepan, whisk together the milk, sugar, cornstarch, cocoa, and salt. Heat until hot and bubbly but not boiling. Add the chocolate and stir until melted. Continue cooking until the mixture thickens, about 1-2 minutes. Remove from the heat then stir in the vanilla. Transfer the mixture to the popsicle molds. It'll be thick like pudding but should still be pourable. Add sticks then freeze until firm, at least 4 hours or overnight.
