Lemon Puppy Chow Snack Mix is a sweet and citrus-y candy treat made from chex cereal, white chocolate, and fresh lemon zest. Ready in just fifteen minutes, you'll love this twist on the classic puppy chow snack, sometimes called "muddy buddies".
In a small bowl, microwave white chocolate chips for 30 seconds, stir. Microwave for additional 30 second increments until chips are melted and smooth. Add lemon zest to chocolate and stir to combine. Pour chocolate over cereal and stir carefully to fully cover but not break the cereal. Pour cereal mixture into a large gallon size plastic bag.
Add powdered sugar to bag, close bag, and shake to evenly coat cereal.
Line a baking sheet with parchment or wax paper and pour cereal mixture into a single layer. Refrigerate for 10-15 minutes (or until chocolate has hardened). Store in an airtight container until ready to serve.
