Start by gathering all your ingredients for the Zesty Lemonade Puppy Chow. Measure out the Rice Chex cereal, white chocolate, butter, lemon zest, and powdered sugar.

In a microwave-safe bowl, combine the white chocolate and butter. Heat this mixture in 30-second intervals, stirring each time, until fully melted and smooth—about 1-2 minutes.

Once your chocolate and butter are perfectly melted, stir in the fresh lemon zest thoroughly.

In a large mixing bowl, pour the Rice Chex cereal. Drizzle the warm lemon-infused coating over the cereal and fold until all pieces are evenly coated.

Transfer the coated cereal into a resealable bag or a bowl filled with powdered sugar. Shake or toss until the cereal is covered.
