Cupcake icing gone brown HELP!!!!

[smellalicious]

my cupcake icing has discolored. I ve not had this problem before. They were made fresh last week.
I put them under a light to dry as it was humid (not done that before)
I used vanilla fragrance which ive done before no problems.
Stressing as i sent 40 off and hope this was a one off

Vanilla will discolor. I've never used one that didn't discolor without a stabilizer.

Is it CP soap?

It was the vanilla, which discolors. I use vanilla stabilizer when I use an FO containing vanilla.

I agree with the others, vanilla discolors unless using a vanilla stabilizer. It's likely to get darker too depending on the amount of vanilla.

I would guess that putting it under the light sped up the discoloration.
