Remove the lid from ice cream container. Working quickly, cut the container off the ice cream and turn ice cream on its side on a work surface. Insert craft sticks into the side of the ice cream, evenly spacing them. Cut the ice cream between the sticks, creating 3 bars.
Arrange ice cream bars in the prepared baking sheet; freeze until completely solid, 8 hours to overnight.
Combine chocolate chips and coconut oil in a microwave-safe bowl; heat in microwave in 30-second intervals, mixing well each time, until chocolate hard shell mixture is smooth, 1 to 2 minutes.
Hold 1 ice cream bar over a separate measuring cup and pour chocolate hard shell mixture over bar to cover completely. Let chocolate dry for a few seconds and pour chocolate hard shell mixture over bar again, creating a thick shell. Place bar back in the waxed paper. Repeat with remaining bars and chocolate hard shell mixture.
