Wash, dry, and remove the core. Then, slice into ¼" - ½" pieces. The thinner the apples are sliced, the easier they'll be to stack and eat.
Layer the sliced apples on a circular plate. You can use whatever shaped plate you want, but a circular one allows for optimal topping coverage in each bite!
In microwave safe bowls, heat the chocolate chips in the microwave in 20-40 second intervals. Be sure to stir between each interval until completely chocolate is completely melted.
Then, drizzle the peanut butter and chocolate over the apple slices in a circular motion.
Chop up your trail mix into tiny pieces. Sprinkle it on top of the apples. You can also top with extra chocolate chips, too!
