How to Make a Letterboard Cake For Your Party

Hi friends! I’ve been loving this cake style on Instagram and Pinterest. There are fun ways to customize to your own liking and choose a theme such as ice cream, bridal showers, baby shower, a 1st birthday, and more special occasions! I have an actual letterboard for my kids every school year, so I thought it would be fun to create a back-to-school letterboard cake in a 9 x 13 dimension. You can choose any fun sayings even inspirational quotes to put on top of the cake! I’ve included a short video below for you who prefer to watch videos than read the step-by-step guide on how to make a letterboard cake.

Which Cake Recipe Should I Use?

You can use any recipe as long it is enough for a 9 x 13 cake pan! You can always bake leftovers into cupcakes or a small cake pan such as 4 inch or 6 inch cake pan. My favorite recipes are the vanilla cake recipe that my friend, Blair, did for me and chocolate cake.

How Do I Make The Letters?

You can use an alphabet mold and a small amount of white candy coating chocolate or fondant cutters and fondant such as satin ice fondant, or letterboard cake toppers.
