Freezing Chocolate Flourless Cake
I haven't tried the CI recipe, but I did make a flourless choc cake and freeze it successfully. I wrapped in plastic and then in foil. I only kept it about 2 weeks in the freezer. Do let it defrost overnight in the fridge and remove about 1-2 hours before serving. No one detected this was made in advance and it made my life a lot easier to be able to prepare in advance. I plan to do this again for Passover, as there is little choices for dessert and this was a great one. I decorated it with strawberries, raspberries and blueberries.
I have not tried this recipe. I worked at a Cafe that made them and kept them frozen. They would have to be protected from the air of a freezer- tupperware, gladware, etc. High fat foods can pick up "flavors" from a freezer.
You would want to let the cake defrost in the refrigerator for 24 hours. Letting it sit out for an hour before serving also is recommended.
