Place chopped peanuts, sprinkles, toffee bits, marshmallow bits, shredded coconut, and crushed Oreo cookies into small shallow bowls and set them aside.
Line a cutting board or baking sheet with parchment paper and make a space in your fridge for it.
Ensure the grapes are completely dry. If grapes are wet, the caramel will not stick. Insert a toothpick into each grape, at the end opposite of where the stem was, and set them aside.
In a small saucepan, add the caramel bits and heavy whipping cream. Heat over low heat, stirring constantly until the caramel is melted and smooth, about 5 to 8 minutes.
With the caramel still over low heat, carefully dip each grape into the caramel, letting the excess drip off. Then, immediately dredge the grape in your topping of choice.
Place the coated grapes onto the prepared cutting board lined with parchment paper.
Once all the grapes are dipped and coated, refrigerate them for about an hour to let the caramel set.
Serve grapes chilled and enjoy!
