This trifle is super easy to make but looks like you fussed all day. Your guests will want to know what's in it so print out some extra copies of the recipe to share.
Tip: Break the toffee bars up with your fingers and use kitchen shears to break up some of the larger pieces before chopping it up in a food processor. That way you won't have to over-chop the toffee to get it crunched up into small, bite-size chunks. The toffee softens up inside the trifle and it's nice to come across it while eating the trifle.
