Yesterday evening I lined a muffin tin with paper liners and filled each cup three-quarters of the capacity with creme brulee mixture. I expected to find them frozen solid this morning, but they are still creamy. There is nothing wrong with my freezer and the other foods are frozen solid. Any idea why they would not freeze hard? The ingredients are: eggs heavy cream erythritol (natural sweetener) stevia glycerite vanilla and topping made of: butter almonds erythritol stevia glycerite Doesn't dairy freeze ok? I have cheesecake in the freezer with basically the same ingredients and they are frozen solid. I am stumped. Please help.
