Ahhh..it could be your cream cheese, as it’s a dairy product. If left out of the fridge, that could definitely cause the bulge. I made a cream cheese ganached cake, and had to keep it refrigerated because of the cream cheese, until I was ready to take the cake to my daughters. Cream cheese will ferment…bubble and expand.
