Awesome recipe. Seriously, it inspired awe in individuals who sampled it. I simply wanted to repost a mascarpone substitute I discovered in another Tiramisu recipe. It labored wonderfully within this one! HEIDI8803 published this in Raspberry Tiramisu, unsure which recipe she first got it from: mascarpone substitute-fpkgs cream cheese combined with 1/2 c heavy cream and 5 T sour cream And, to reiterate other advice provided by previous reviewers, I too made two three cake layers using the instant coffee (I'd've managed to get three, however the altering colors are beautiful) and that i bending the coffee liquer everywhere it had been known as for. I believe the next time I'm likely to add chocolate covered espresso beans around the bottom of the wedding cake. ***Edit*** I've chose to make this a couple of occasions now, and learned (hard way) one big factor around the frosting: It is best to under whip than over. Greater than 5 minutes and also you risk hitting an icky butter zone. That could be what went down to Nicky. Right at 5 min. works best for me. Oh, and believe all of the reviews about letting the wedding cake sit overnight. The frosting sets better for the reason that time.
