I know it is frustrating. I have that happen, too.
I just wanted to add that the cakes that fell apart do not have to be wasted. You can also make cake bites. They have been discussed on this site before. Here is a recipe provided by Cookieman. You can substitute milk or coffeemate for the amaretto or add whatever ingedients appeal to you.
I went through and found the other thread, below is a quote from Cookieman:
I added the amaretto to the crumbled pieces of leftover chocolate cake I had on hand. I just winged the recipe from what I remembered of other recipes I have tried. In a bowl, I crumbled up about a cup-and-a-half of cake, mixed in a couple of tablespoons of confectioners' sugar, a healthy shot of amaretto, and some chopped almonds. I then mixed the whole thing with my very clean hands until it held together. The trick is to not let the mixture get overly moist, but not have it be dry and crumbly either. I then took a tablespoon cookie scoop and made balls out of the mixture. I let them dry out for a while on a parchement-lined cookie sheet (I let them dry for only about an hour, but idealy it should longer; even overnight) and then proceeded to dip them in melted chocolate candy melts. ( I made my own dipping fork by removing the two middle tines from a four-tined plastic spoon.) Then, back to the parchment-lined cookie sheet and into the freezer for 5 minutes to harden the chocolate shell. There you have it: chocolate-covered amaretto balls!
