Step 1

Line three baking sheets with parchment paper and set aside.

Step 2

Unwrap the Reese's peanut butter cups and place them large side down on one of the baking sheets.

Step 3

Use the color mist to spray the peanut butter cups all over following the directions on the can. Let dry while you make the Oreos.

Step 4

Add the color melts to a microwave-safe bowl and melt for 1 minute, stir then melt at 30-seconds intervals, stirring between each one until smooth. Use separate bowls for each color and work with one color at a time for the best results.

Step 5

Add an oreo to the melted candy and use a rubber spatula to scoop the candy over the top of it.

Step 6

Use a fork to scoop under the Oreo and lift it out, tapping until all the excess candy falls off, then sliding the bottom of the fork against the bowl.

Step 7

Use a toothpick to help slide the Oreo off the fork onto the prepared baking sheets.

Step 8

Then add the 2D icing decorations and additional sprinkles to decorate the candy-coated Oreos. Work in batches of three to that the candy doesn't harden before the decorations can be added.

Step 9

Let the Oreos set completely, about 10 to 15 minutes after being dipped.

Step 10

Reheat the candy melts if needed for 15 to 30 seconds until smooth again.

Step 11

Dip the bottoms of the Oreos about ¼-inch into the candy melts and then gently press them on top of the peanut butter cups, holding each one for 10 to 20 seconds to ensure it stays. Some of them may feel heavy and like they want to fall over, but they will stay if you just hold them a bit as the candy melts start to do their thing pretty quickly. You can stick the peanut butter cups on while the Oreos are lying down and setting, but the cups will be at a bit of an angle and not quite as secure; if you're just making them with the kiddos, this might be the easiest option.

Step 12

Let set completely before enjoying, about 15 minutes.
