Funfetti Puppy Chow

This is entirely too good!  The nutritional info seems off. I figured it using Mastercook, but it seems off...maybe my own wishful thinking that this would have fewer calories?

Funfetti Puppy Chow
1 ½ c. white chocolate chips
1/2 c. Splenda w/ fiber
1 c. funfetti cake mix (powdered)
3 c. Rice Chex

4 c. wheat Chex

In a small bowl, combine cake mix and Splenda; set aside. Measure out cereal; set aside. Melt white chocolate chips in large bowl in microwave. Add cereal and combine well. Once cereal is completely coated in white chocolate, dump the cake mixture on top and gently toss to coat each piece. Spread out on parchment paper to cool completely then store in a gallon ziplock bag for later (if you have the self-control!) or enjoy right away!
