Wash your apples thoroughly, then slice them into thin, even rounds about a quarter-inch thick. I like keeping the skin on for extra fiber and color, but you can peel them if your kids prefer it that way.
Lay the apple slices out in a single layer on your serving platter, slightly overlapping if needed. Spreading them out like this makes the whole snack feel more like a fun little board than a plain plate of fruit.
Microwave your peanut butter for about 10 seconds until it loosens up. Use a spoon to drizzle it back and forth across all the apple slices, covering as much surface as you can for maximum flavor in every bite.
Sprinkle the chocolate chips, granola, coconut, and chopped nuts evenly over the top. Let the kids help with this step if they're around, since choosing their own toppings makes them far more excited to actually eat it.
This snack tastes best right away while the apples are still crisp and the peanut butter is soft. Serve it straight from the platter so everyone can grab a slice and dig in.
