Size, ingredients, flavors can affect thawing times

If the ice cream cake is quite sizable—let's say 12 inches by 16 inches—you might need to allow it to defrost for around 45 minutes. Another factor to consider is the flavor of the ice cream. For example, chocolate will require a bit more time to soften compared to vanilla. Flavors like caramel or rum will thaw even faster. Additionally, homemade ice cream cakes may defrost more quickly than their store-bought counterparts.
While the best way to thaw an ice cream cake is in the refrigerator, you can also let it sit on the countertop if you're short on time. As a general guideline, take the dessert out of the freezer about 10 to 20 minutes before you plan to serve it. Sasha Zabar, the founder of Manhattan's Glace by Noglu, suggests a combination of both methods. She recommends thawing the ice cream cake in the fridge for 45 minutes, followed by 10 minutes on the counter. Once your ice cream cake is ready, be sure to serve it with an ice cream fork—a stylish spork that merges a spoon and fork, making it ideal for enjoying this creamy, sweet treat.
