The ingredients won’t appear on the screen until you’ve removed the top block of meringue, so try to make sure you’ve crushed your way through it before you destroy either of the cakes. Make your matches into the meringue barrier, or down into the cake, and remove the licorice swirls to ensure a clear path for the ingredients.

The cake explosion should clear out three of the ingredients leaving you with just a few candies to clear to free up the final ingredient. Old fashioned vertical striped candy should help you here!
