No, but mostly because I doubt it would be worth the calories and I'm not sentimental enough to care about throwing it away (which is what I wanted to do with our cake remainders until my mom essentially force fed it to me). I wouldn't be scared of it or anything.
We just ate our four-year-old wedding cake over Labor Day weekend. We had a few bites each. If it had held up better, we probably would have eaten more of it.
