Use this page to learn how to make a Cookie Monster cake, an adorable Sesame Street-themed homemade chocolate chip birthday cake. I love this decorating method because it’s pretty easy, even if you’re a cake decorating beginner. You don’t need any fondant or special molding ingredients for Cookie’s eyes and mouth.
For my oldest’s 2nd birthday, I made an Elmo cake, so it seemed very appropriate—necessary, even—to make a Cookie Monster cake for my youngest’s 2nd birthday! Her older sister loves Elmo, so Cookie Monster has naturally become a favorite character around here.
I’m not an advanced cake decorator. While I’ve improved with dedicated practice over the years, you won’t see me making super elaborate cake designs—a naked cake is more my speed! However, this is a surprisingly simple cake to decorate. The hardest part is the tedious task of piping all of Cookie Monster’s fur, so take a few breaks to give your hand a rest.
C is for cookies. And cake. And chocolate chips.
This cake is so much fun because it includes chocolate chips inside, and it also includes chocolate chip cookies outside. [Monster voice] COOOOKIEEES. I made a batch of mini chocolate chip cookies using my recipe for mini M&M cookies, just subbing mini chocolate chips for the mini M&Ms. These are perfect for adding around the Cookie Monster cake, and also perfect for little cookie monsters to eat!
If you want to make full-size cookies for your Cookie Monster cake to be “eating,” you can really choose any of your favorite cookie recipes. I made these chewy chocolate chip cookies. I think he liked them. [Nom nom nom nom]
The focus of this cake is the top (as opposed to the sides), so I opted for a shorter 2-layer cake. (Also, the taller the cake, the more piping you need to do!) My 2-layer white cake recipe promises a soft and flavorful cake with the fluffiest texture. It’s always a hit, especially for birthday parties. This time, I added mini chocolate chips to the cake batter, and all I have to say is YUM.
Always line your round pans with parchment paper rounds before adding the batter to prevent it from sticking to the pan!
Cool, then level the cakes: The baked cakes will have a slight dome, so carefully level them off with a cake leveler or serrated knife. **Save the scraps because they will be used for Cookie Monster’s eyes.**
Now that you have your cakes ready, let’s begin to assemble and decorate.
Let’s see those decorating steps come together. Most of the frosting is tinted blue, then tint some black and leave the rest untinted:
Layer the cooled and leveled-off cakes together with untinted buttercream between them. Use some of the blue frosting to apply a very thin crumb coat:
The crumb coated-cake must chill for at least 30 minutes to help set the cake, so start Cookie Monster’s eyes while you wait.
You don’t need anything extra like rolled fondant or modeling chocolate to shape Cookie Monster’s googly eyes. Rather, simply use the scraps of cake that you leveled off, mixed with some of the white (untinted) buttercream frosting. Then we’ll coat them in melted white chocolate. We’re basically making 2 cake pops, sans sticks. My taste testers actually thought the eyes were exceptionally delicious, which is a little bit creepy, but there you have it.
Shaping Tip: Only add enough frosting to the cake crumbs to yield a semi-moist mixture that you can shape into his eyes. Form into 2 disc-like circles, about 2 inches in diameter, flattened slightly. Freeze or refrigerate until solid, about 30 minutes.
After they’ve had a chance to solidify, melt the white chocolate. Chop up a bar of white chocolate (I like the Ghirardelli kind, found in the baking aisle), and melt in the microwave in 20-second increments, stirring after each time. Dip the eyes into the melted white chocolate until completely coated, and lift out with a fork. Place on a sheet of parchment paper and chill in the refrigerator until the coating has set.
The eyes require 2 quick rounds of chilling, so circle back to the cake as you wait. Form the mouth and pipe the fur:
Once the white chocolate coating on Cookie’s eyes has set, pipe the black pupils with a round piping tip—remember to make them googly—and gently press onto cake. Cookie Monster’s pupils are usually looking in opposite directions; I assume this is an adaptation that helps him spot cookies no matter which way he’s facing. LOL
