Notes

*If you glazed has cooled too much, microwave for 15-30 seconds and whisk, repeat until fully melted. Cool again until 90-95 degrees F.
** Between batches, scape up glaze on the bottom of the baking dish into a microwave-safe container to use again.
***Since, I kept the cakes at home and did not travel with them so I did not add an adhesive. To keep the mousse and cake from moving add a tiny bit of leftover glaze to act as a glue between the mousse semisphere and cake.
****You can make them a day before you plan to serve. Keep them refrigerated if you do make them ahead of time. But, bring them back to room temperature prior to serving.
*****Leftover mousse? Place in an airtight container and enjoy with any leftover cake, and oreo crumbs you have. Make sure you store leftover mousse in the refrigerator to set.
Note on timing: The timing is a rough estimate for this dessert. For this recipe, I broke it up into 2 days. Day 1: make cake and mousse. freeze. Day 2: Make the red glaze. While it cools, make devil horn candies, oreo dirt, cut out cake rounds, and assembly. Give yourself a few hours for the entremets to come to room temperature before eating.
