Invisible Cookie Dough Ice Pops

In a microwave-safe container or glass measuring cup, microwave milk 30 seconds or until warm to the touch. Add brown sugar and salt and stir until dissolved. Add vanilla. Place 1/2 tablespoon chocolate chips in the bottom of each of four 1/3-cup ice-pop molds or small paper cups. Top each with milk mixture. Insert sticks and place molds in freezer. Freeze until solid, at least 3 hours. To release pops, run molds under warm water 20 to 30 seconds; they should slide right out. (If using paper cups, simply peel cups away and discard.)
