Growing up Cookie Monster was my favorite character.   I had my Cookie Monster stuffed animal on my bed through Jr. High School.  When Nancy and I were working on the cakes for our Sesame Street Birthdy Party I knew we had to devote some extra time to Cookie Monster.  I loved the way he turned out.  In fact, I loved it so much I insisted we make cupcakes to match.

Ingredients You Will Need

All the ingredients you will need to make a Cookie Monster Cake including cake pan, cake mix, buttercream frosting, blue food coloring, jumbo chocolate chip cookies, Oreo cookies and brown M&M's.

How to Make the Frosting

Step 1: The key to these delicious cupcakes is our Best Buttercream Frosting recipe.   It is light and creamy and buttery and super delicious! You will find the recipe and directions here.  One batch of frosting should be enough to frost the cake. 
Step 3:  Tint the frosting Cookie Monster Blue, we used 5 drops Blue Wilton Color Right Food Coloring to get this bright shade of blue.

How to Frost the Cake

Step 3:  Make chocolate cake.  You can use a cake box mix, we have all the instructions you’ll need to make it taste just like homemade right here. 
Step 4:  We put a layer of frosting between the two layers of cake.  
Step 5:  Frost the rest of the cake.
Step 6:  You will be adding the frosting “fur” next so you don’t need a thick layer of frosting at this point. A normal crumb coat will be fine.

Step 7:  You create the muppet fur by using a pastry bag filled with buttercream frosting and a Wilton Frosting Tip #233. This is the tip you would normally use to make a “grass” like texture on a cake.  
Step 8:  Add the Cookie Monster fur to the sides of the cake.
Step 9: Fill in the top of the cake with fur frosting.

How to Decorate the Cake

Step 10:  The Cookie Monster’s face is very easy to make.  Twist open an Oreo Cookie and use the side with the cream filling for the eyes.
Step 11:  Press the Oreo cookies onto the top of the cake and then press a brown M&M into the oreo cookie filing to create Cookie’s eyeball.  Remember to offset them so he has those crazy googly eyes.

Step 12:  Use a sharp knife to cut a slit into the top of the cake.
Step 13:  Place a large Chocolate Cookie into the slit on the top of the cake.  This is the Cookie Monster’s mouth stuffed with cookies! We bought a jumbo Chocolate Chip Cookie from the grocery store bakery but you could bake one yourself.
