In a medium bowl, combine 1 package of white chocolate instant Jell-O pudding mix with 1 3/4 cups of whole milk. Whisk vigorously for about 2 minutes until smooth.

In another medium bowl, mix together 1 package of chocolate instant Jell-O pudding mix with the remaining 1 3/4 cups of cold whole milk. Whisk for about 2 minutes.

Grab a clean plastic gallon-sized bag and layer spoonfuls of the white chocolate and chocolate pudding to create a swirl effect.

Snip off the corner of the plastic bag and pipe the pudding mixture into each popsicle mold, alternating flavors.

Transfer the filled molds to the freezer and freeze for at least 3 hours or overnight for best results.

Once frozen, dip the bottoms of the molds in hot water for about 10 seconds, then gently pull on the sticks to remove the pops.
