This Wendy’s frosty recipe is almost better than the original. You only need three ingredients- Chocolate milk, sweetened condensed milk, and Cool Whip. Make in an ice cream maker, the preferred method, or using a mason jar. We are obsessed with dipping fries into Wendy’s magic chocolate frosty. The combination of salty and sweet is irresistible and dreamy. But the closest restaurant is far enough away that we don’t get to indulge as much as we would like. So it only made sense we would learn to make our own. The three frosty ingredients you will need are fairly basic. All together I spend less than $6 and had enough for 8 generous servings! So head to the grocery store and pick up.
