The amount of cake required for 100 people can vary depending on several factors, such as the serving size and the type of event. However, as a general guideline, you can estimate the amount of cake needed based on the assumption of a standard serving size of 1" x 2" x 4".
If you're serving a single-layer cake:
- For square or rectangular cakes: A 9" x 13" cake pan typically yields about 24 servings. So you would need around 4 pans to serve 100 people.
- For round cakes: A 10" round cake pan typically yields about 28 servings. So you would need around 4 pans to serve 100 people.
If you're serving a double-layer cake:
- For square or rectangular cakes: A 9" x 13" double-layer cake typically yields about 48 servings. So you would need around 2 pans to serve 100 people.
- For round cakes: A 10" round double-layer cake typically yields about 56 servings. So you would need around 2 pans to serve 100 people.
Keep in mind that these estimates are approximate and can vary depending on how the cake is sliced and served. Additionally, if you're planning on serving other desserts alongside the cake or if you expect people to take larger portions, you might want to adjust the quantities accordingly.
