To make a tall sponge cake for a 20 cm springform pan, you can increase the recipe by 50% to ensure you have enough batter for a taller cake. This means using 1.5 times the amount of ingredients listed in the original recipe. Make sure to adjust the baking time accordingly, as a taller cake may require a slightly longer baking time.

This conversion allows you to use a springform pan for recipes that call for a regular cake pan. **
