The first thing you have to do is to get rid of the chocolate as soon as possible.
From there, you can clear all 4 candy bombs, worth 12,000 points which means you only have to score 18,000 more points to clear the level. No additional candy bombs will appear, so there is no need to worry after destroying them. But that also means that you have to be quick and do lots of cascades.
The last thing is to get rid of the 4-layer meringues. You don't want to play only on one side of the board, otherwise you'll be unable to reach the score requirement, as you're missing half the board's potential.
Make sure you grab +5 candies on the way. They'll really benefit you for this level.
If you are completely stressed by this level and cannot beat it, here's an easy way to pass it. If you have a color bomb booster available, activate it and enter the level. Now, use the color bomb on a color that a candy bomb is, too. This will score you near if not over the required score.
