A good recipe for Chex Mix puppy chow includes 9 cups of Chex Rice cereal, 1/2 cup of peanut butter, 1 cup of semi-sweet chocolate chips and 1 1/2 cups of confectioners' sugar. To make a batch of this snack, combine the chocolate chips and peanut butter in a saucepan, melt the two ingredients together over low heat, stir them until smooth, remove the mixture from the stove, and add the Chex Rice cereal.
Stir the cereal into the chocolate and peanut butter mix. Stir gently to ensure none of the cereal is crushed. Once the cereal is coated in the melted chocolate and peanut butter mixture, pour it into a gallon-sized plastic bag. Pour the confectioners' sugar into the bag, and zip it closed. Next, shake the bag until the cereal is fully coated in confectioners' sugar.
To store the finished product, place the Chex Mix puppy chow in an airtight container. Store the puppy chow in another plastic bag or a Tupperware container. This recipe is easy to modify, such as by adding chocolate or peanut butter to boost its flavor and give the cereal a thicker coat. Add-ins such as chocolate chips, candies or vanilla boost the flavor as well.
