Notes
I like to make my famous homemade fudge brownies for this trifle, but you can use a box mix if you're short on time.
What is a trifle?
A trifle is originally a French dessert coming from the French word for truffle. A true trifle is made with egg custard over cake and topped with whipped cream. This is basically a delicious, Americanized version of the real thing.
Can you make a trifle ahead of time?
Yes, absolutely. That is one of the very best things about this dessert. You could even make it a day in advance and just keep it in the fridge until it's ready to serve.
What is the difference between a trifle and a parfait?
A trifle and a parfait are very similar in concept. They are both basically layers of pudding or yogurt, chocolate, fruit with cake, cookie or brownie pieces.
