Level 2109 - Dilema

On Level 2109 - I am so disappointed because I had only two hand swap boosts left (nothing else) and I used both of them to set it up to get a cake bomb and then have a red candy drop down so that I could use the bomb with the red candy to detonate two red candies left to win the game, but soon as I did the swaps, the red candy I anticipated to fall into place, just disappeared for no reason that I could see.  I don't have enough gold bars or anything left to explode the remaining two red candies, and I have been working on this level for awhile and I am anxious to move on.  This is on my iPhone.  Do you have any suggestions on how I can finish this game - there is a red candy close to the bomb, but not close enough and I have nothing to grab or swap it with.  I wouldn't be asking except that the red candy that disappeared should not have and I should have been able to use it.  I hope you understand my explanation. 

Thank you for any advice or help you can provide.
