I found a FAST way to boost this achievement but you need to reset your progress by reinstalling the game.
After that finish the tutorial level and move through the game as far as you can.
after you die the game try to force you to buy the first upgrade the magnet.
at this point
DONT BUY ANYTHING.
Close the game fully and start it again. Sign in again. and the tutorial level starts again. After you found the 4 to 6 sweets you only can found golden Palm trees and Diamonds. do this over and over again till you get your palms (20-30)
hope this helps for me it was the easiest and fastes way in could figure out :)
