Steps in Baking a Cookie Monster Birthday Cake

Updated February 21, 2017

A child who loves Sesame Street might request a themed birthday party that focuses on Cookie Monster. This exuberant character is known for his royal blue fur and his habit of gobbling up chocolate chip cookies. As the centrepiece on the food table, make a birthday cake that looks like Cookie Monster. Although there are many ways to fashion the cake, one simple variety focuses on only Cookie Monster's face and is appropriate even for inexperienced bakers.

Bake two round cakes and two cupcakes according to your cake mix recipe and allow them to cool thoroughly in their pans.

Turn the first cake out onto a round platter. If necessary, slice off the rounded top of the cake so it is flat.

Spread a layer of white icing on the first cake. Place the second cake on top of it. Leave the top of this cake rounded.

Trim the edges of the cupcakes so they are mostly spherical, but with a flat bottom. Place a dab of frosting on the bottom of each cupcake and attach both cupcakes to the top of the cake, touching one another, as Cookie Monster's eyes.

Spread a thin crumb coat of white icing over the entire surface of the cake. Refrigerate the cake for 30 minutes, or until the icing hardens.

Mix the royal blue food colouring with all but 1/2 cup of the remaining white icing. Place the blue icing in the pastry bag and attach icing tip number 233, which has many small holes that will pipe out strands of icing that look like fur.

Spread the remaining white icing over the cupcake eyes. Put two large circles of black icing on the eyes as the pupils. Stagger the positions of the pupils to give Cookie Monster a wild look.

Spread black icing in a semicircle on the bottom portion of Cookie Monster's face to make his mouth. The top of the mouth should be curved slightly in like a large crescent moon.

Pipe blue fur over the remainder of the top and sides of the cake with the icing bag and tip you prepared. The pieces of fur should be at least 1/2 inch long.

Break the chocolate chip cookie into one large piece and a few small pieces. Place the large piece in Cookie Monster's mouth and arrange the small pieces around it so it looks like he is excitedly eating the cookie.


Mix the royal blue icing the night before and refrigerate it overnight to produce a more vibrant colour.
