Yes, we use Betty Crocker most often, but also use Pillsbury once in awhile. The nice thing about Pillsbury frostings is they have some that are safe for milk allergy too, so I would use that for other kids I knew with that allergy.
I made 2 Betty Crocker cakes this am, and have BC cans of frosting for them. Cake Walk tonight.
We use McCormick food coloring and Signature brand or Cake Mate sprinkles.
