Melt the Magic – In a microwave-safe bowl, heat the white chocolate almond bark for 1 minute. Stir well, then heat in 20-second intervals until completely melted and smooth.
Mix the Goodies – In a large bowl, combine Chex cereal, pretzels, Lucky Charms cereal, and half of the M&M’s.
Coat with Sweetness – Pour the melted chocolate over the mix and stir until everything is well coated.
Set the Spell – Spread the mixture onto a baking sheet in a single layer. Sprinkle the remaining M&M’s and Lucky Charms marshmallows on top before the chocolate sets.
Let It Harden – Allow the mixture to set for about 1 hour until the chocolate is firm.
Break and Enjoy – Once hardened, break into bite-sized pieces and serve.
