A letter cake is beginner-friendly for several key reasons:

Prepare the Sugar Dough Cake Layer

Begin by mixing up a sugar cookie-style cake layer. I love using cookie dough as the base of my letter cakes because they are so sturdy. 

This recipe yields enough batter for a two-layer single-letter cake. If you want to make multiple letters or numbers, just bake one batch for each letter. 

Each letter cake will serve approximately 10-15 people. 

Bake Your Cake

Spread the cake batter onto a 10×15″ cookie sheet. Use wax paper to help spread your batter evenly. A good rule of thumb for baking time is to check after 13 minutes and every few minutes after until a toothpick comes out clean from the center.

Cut Out the Paper Template

Creating a number or letter template for your letter shapes is easy. Here’s how to do it:

  1. Design Your Letter: Use a computer to design the letter in the size and font you want. Make sure it fits the dimensions of your cake. Print the letter onto a piece of paper. If you prefer, you can draw the letter by hand.
  2. Cut Out the Template: Use scissors to carefully cut out the printed or drawn letter. This will be used as your guide for slicing your cake into the perfect shape.

Shape  the Cake

 After the cake has baked, let it cool in the pan for about 15 minutes. Then, invert the cake onto a cooling rack to cool fully.

Once cooled, cut the cake in half so there are two equal-sized portions about the size of the letter.  Avoiding the outside edge of the cookie cake, place the paper template on top of your cake layer.

 Use a sharp, thin knife to carefully cut around the template. Repeat a second time to cut the second layer. 

Make the Buttercream

To create a sturdy base for holding up the second layer of the letter cake, I like to use a stiff vanilla buttercream.  

One of my favorite designs is an all-white buttercream with fresh flowers and fresh fruit on top.

If I’m matching a color scheme, I pick three colors for the top of the cake and keep the decorations simple, using sprinkles as my main accent.

 Assemble the Cake

Once your cakes are baked and cooled, it’s time to assemble. 

With your cake layers and buttercream ready, you can now assemble your letter cake:

  1. Prepare Layers: Once your cake has cooled, use your paper template to cut out the letter shapes from each cake layer. Since this cake does not require leveling, simply cut two identical shapes for each letter you are making.
  2. Stack and Fill: Start by filling a piping bag with buttercream and attach a large round pastry tip. Place the first layer of your letter on a cake board or serving platter. Pipe generous dollops of icing onto the first cookie layer.
  3. Carefully place the second cookie layer on top of the icing dollops and continue the process. After you’ve decorated the top cookie layer with icing, go ahead and sprinkle your favorite toppings over the cake to finish it off beautifully!
