To make the best number cake for the birthday of your loved ones you must follow these steps: 1. Go trough ingredient list and make sure you have all the ingredients ready. 2. To avoid mistakes, before you start making the cake, read the recipe instructions at least one time and watch the full video. Make sure you understand the whole process. 3. Print and cut the numbers/letters in advance. 4. Make sure you chill the dough in the fridge. 5. Decide how to decorate the cake before you start. 5. Don't assembly the cake ahead of time, otherwise the tart will become too soggy after one day.
