My kids love ice pops. We used to all have one a day during the hot summers of Georgia. The ones we get here don't taste great and are very expensive. So I invested in popsicle molds and tried many online recipes. We have had so much success that we ended up buying more popsicle molds.
Here are our favorite recipes and ideas:
Pudding Pops - make a package of pudding with 1 1/2 cups of whipping cream rather than milk. Mix it until it is a mousse. It takes a little practice getting the mousse into the molds, but it is worth it. Also we use this recipe for cake filling.
Regular Popsicle - Make a package of Jello according to the directions, but also add a cup of sugar which helps prevent the formation of ice crystals so it is easier to eat. The flavor of these popsicles is very mild, so if you want more flavor then just add a package of the same flavor of Kool-Aid.
Fruit Pops - I get my kids to eat a serving of fruits with these popsicles. You need to find a good flavor of fruit smoothie, not juice, and buy some none sweetened unflavored apple sauce. Measure out how much your popsicle molds can hold. Then just mix half smoothie with half apple sauce. The apple sauce helps prevent ice crystals as well and helps the popsicle from getting hard as a brick.
These are the two molds we have, the swirly ones are usually what we put the pudding pops and regular popsicles in, but the tubes we use for the fruit pops because my kids like those Fruit Chillers. These are both silicone molds which I like because it is easy to get the popsicle out of and it is super easy to clean, i.e. you can toss them in the dishwasher when you are done. tube molds are also great for making your own Pedialyte pops. The twirly pops are nice too because the stand breaks down for easier storage and the handles have a small cup which prevents messes with the little one. If you want to make the "No Melting" popsicles, you simply add a package of unflavored gelatin to the mix.
