Caramel Apple Cake Mix Bars – all of the flavors of the season with layers of cinnamon, caramels, chopped apple, and toffee bits, all drenched in delicious sweetened condensed milk. I took these to a party and they were gone in minutes! Cake mix, eggs, butter, toffee bits, apples, cinnamon, caramel, and sweetened condensed milk. These are best if you make them the day before and refrigerate them overnight. Great for parties and potlucks.
