I found this recipe at Smashed Peas and Carrots.
I have always loved Muddy Buddies, so when I found a recipe for these, I knew that I needed to try them! If you love lemon, you will love these!!
6 cups Rice Chex cereal
1 bag white chocolate chips
1 1/2 cups lemon cake mix
Measure cereal into a large mixing bowl and set aside. In a microwaveable bowl, microwave chips, butter, lemon peel and juice uncovered on high for 1 minute; stir. Microwave about 30 more seconds or until mixture can be stirred smooth. Pour mixture over cereal, stirring until evenly coated. Pour into a 2-gallon resealable food storage plastic bag. Add powdered sugar, seal bag and shake until all the cereal is well-coated.
