For Kyra in FL regarding frosting mix:
This is for coconut pecan frosting mix, but maybe you can adjust it.

Coconut Pecan Frosting Mix

1 box dry vanilla frosting mix
1 box chocolate frosting mix
1 cup chopped pecans
1 cup over toasted till golden coconut
Combine all of this, and divide in half. Half of the mix can then be prepared per box directions as
given on either the vanilla or chocolate frosting mix.
