Feel free to use whatever ingredients you like in this caramel apple bark. Any kind of apples would work well, you could use dark, milk or white chocolate and you can use whatever kind of nut that you like. I chose to use dark chocolate, pretzels, pecans, Honeycrisp and Granny Smith Apples and of course, caramel. Caramel Apple Bark is super easy to make and makes an awesome gift! Just make a batch, freeze, break it into pieces and store in a storage container or a cute plastic bag.
