Melt the pink candy melt with 1 tsp oil in 30-second increments in the microwave until fully melted.
Pour over Chex mix, gently fold until it is coated in that mixture. If the candy melts seize and harden on you, you can always microwave everything for 15 seconds then stir to coat again.
Place the mixture in a ziplock bag, add 1/2 cup powdered sugar, and shake to coat. Pour everything on a wax paper-lined baking sheet and set aside.
Repeat that process with the red candy melts, oil, and leftover Chex cereal. Coat with the powdered sugar and place on the wax paper-lined baking sheet.
Let the muddy buddies set for 30 minutes then mix in the M&m's and sprinkles.
Enjoy!
