Preheat oven to 250°F. Place the Chex and pecan halves on a large baking sheet lined with a silicone mat or parchment paper.
Place the butter, brown sugar, and corn syrup in a medium saucepan over medium heat. Cook until the butter melts and the sugar is dissolved.
Stir in the cinnamon, ginger, baking soda, and kosher salt. Mixture will foam a little bit.
Pour the butter and sugar mixture over the Chex and pecans. Toss to combine.
Bake for 60 minutes, stirring every 20 minutes.
After 60 minutes, remove from the oven. Cool for 5 minutes, and then pour the mixture onto wax paper to cool, breaking it up with your hands.
Stir in the apple chips. Let cool completely and store in an airtight container.
Notes
You can use any combination of Wheat Chex, Corn Chex, and Rice Chex that you like. I prefer to use an equal mixture of all three for the color and flavor variety in the mix. If you want to make this gluten-free, omit the Wheat Chex and use an equal mixture of Corn Chex and Rice Chex instead. Why add the apple chips at the end? They will get rock hard in the oven. They're already dried so baking dries them out even further! Add them at the very end, after the mixture has cooked (it's ok to add them when the mixture is still warm).
