Cobblers, slumps, and high-rise Dutch babies made in a cast iron skillet are cozy and comforting. However, as rustic as these rough and ready desserts may look at first glance, they do require a fair amount of prep work, such as preparing biscuit dough or chopping mounds of fresh fruit. One way to make easy cast iron skillet desserts that are ready in a fraction of the time is to use pancake mix as your base. This awesome shortcut simply needs a bit of water, and then it can be poured straight into a hot skillet along with a few extras to create an array of desserts at rapid speed. Pancake mix contains flour, raising agents, eggs, sugar, and, in some cases, buttermilk in powdered form.
