Pop the kernels in an air popper. Transfer to a large bowl making sure to remove all the un-popped kernels. Stir in the candy corn, reese's pieces & pretzels. Next, melt the almond bark in the microwave according to the package directions. Stir in the peanut butter till it's all nice and smooth. Pour the chocolate/peanut butter mixture over the popcorn and gently stir till all the popcorn is coated. Transfer to a baking sheet lined with parchment paper or foil. Once the chocolate is set, break up into pieces & serve.
Store in a ziplock or air tight container. Can be put in the refrigerator to speed up the hardening process.
Notes
I like to use the almond bark that comes in a microwavable tray. So much easier and you just toss it when your done! Also, I always spray my measuring cup with cooking spray before I measure the peanut butter. It will come out much easier.
