Vanilla Number Cake

A number cake is such a fun and personalized way to celebrate a birthday—especially for kids! For my daughter’s special day, I made a soft and fluffy vanilla cake and cut it into a big number 5. It’s simple, creative, and looks like something straight out of a bakery—but you can absolutely make it at home.

Vanilla Number Cake

I love baking cakes for my kids’ birthdays – There’s something exciting and exhausting about taking the time to create a cake just for them.

First, you’ll start with a classic vanilla sheet cake that’s sturdy enough to cut and shape. Next, once the cake has cooled completely, you’ll use a template to cut out the number 5 – I used this one. Then, you’ll prepare a smooth buttercream frosting to decorate and bring it to life. Finally, you’ll add fun toppings like sprinkles, fruit, or candy to make it extra special for your child
