One of the most popular copycat recipes on my blog... Wendy’s Copycat Frosty Dessert! Tastes just like the original! When asked what my favorite dessert is, I am sometimes embarrassed to tell people that it's the Wendy's chocolate frosty. I know most people love decadent desserts and I love many of them too, especially the Italian ones, but in Minnesota they are hard to come by and so I move on to my favorite Wendy's chocolate frosty. I'll order it even when the temps are 30 below zero.
