With a salty and sweet Biscoff cookie crust and a tart key lime pie layer, these bars are dipped in a chocolate for a refreshing summer treat.
You can most definitely say that key lime pie is the key to my husband’s soul. It’s his ultimate weakness. Every year for his birthday, Christmas, our wedding anniversary, and Father’s Day, his little wish list is simple. Key Lime Pie. 
Whenever I’m scouring recipes for pie bars, cookie bars that have a crust, or a tart that calls for graham cracker crumbs, I laugh. Do these people even know what Biscoff cookies are? Making your cookie crust out of these heavenly little famous airline cookies will change your baking game. Its got a nice little cinnamon ginger bite to them, and just add so much more flavor to your crust. Throw in some pecans and you’re in business. This recipe was slightly adapted from Martha Stewart and of course, I made the crust quite differently. Once the bars were done, I dipped them into some melted dark chocolate and coconut oil. Then sprinkled them with lime zest. They totally remind me of the chocolate dipped key lime pies on a stick down in Key West! You cannot skip that experience if you are ever in Key West. First off…pie on a stick. Enough said.
