Trifle is an interesting thing. It can be done in so many many ways and they are not all created equal. Some trifle's are made with cake mix and a box of pudding and some are made purely from fresh ingredients that just taste better. If you are temped ever to use a box just remember that it doesn't take that much more effort to make it a desert everyone will remember. This Mixed berry trifle is THAT GOOD. You will remember it and yes-do make enough for leftovers.
I used THIS RECIPE and only changed two things. Instead of using the orange juice and orange liquor I peeled three oranges and put them whole into my Vita-Mix and blended them until they were frothy. I measured out what I needed and my kids fought over the leftovers. It tasted like the Orange Julius's my mom used to make for us when we were kids. So much better than regular orange juice.
The second thing I changed was not by choice. If I could have found the mascarpone the recipe called for I would have happily used that, but unfortunately I wasn't able to get my hands on any around here and so I ended up using cream cheese instead.
A little tip for using the cream cheese: make sure it is really soft before you use it. Leave in out on the counter until it is warmish. Then beat it in a mixer, scraping down the sides until it is really soft and will easily fold into the whipped cream. If it isn't soft enough, it will end up in lumps in the whipped cream instead of perfectly blended. But remember if you can get your hands on mascarpone use that instead and if not then the cream cheese is a great second.
