Tips for Decorating

Here are some helpful tips for making this easy monster cake. While this Sesame Street Cake is stunning, just know it is easy. Don’t make it harder than it has to be.

Gently push the mini chocolate chip cookies into the frosting around the edge of the cake.
You can pipe the chocolate ganache at the edge to create that stunning drip look.
Choose any piping tip you like for the top, and place an Oreo cookie then a dollop of frosting. Start with frosting so your cookie has somewhere to lean.
The cookies will become soft after being stored in the refrigerator for a while, so we recommend holding off decorating until you are ready to serve it.

Storage

Refrigerate: Your cute cookie monster cake will need to be stored in the refrigerator. Make sure to place it in an airtight cake container.

The cake will store for 4-5 days in the refrigerator. You will find it is best in the first few days, as it can dry out a bit.

Start by preheating the oven for 350 degrees. Then spray each cake pan with cooking spray. We used 9 inch pans, then place parchment paper inside the pans as well.
In a stand mixer take your cake mix, eggs, butter, milk, and mix well. Divide the batter into the 3 round cake pans. Bake for 20-30 minutes or until the cakes are fully cooked.
Place on a cooling rack and allow to cool completely.
With a cake leveler you will slice off the tops to remove the dome top on the cakes to make it evne.

Cookie Dough Frosting

Place raw flour in a container and microwave for 1 minute. This will kill the bacteria in the flour. It needs to reach 160 degrees.
Next you will take your stand mixer and add your butter, powdered sugar, brown sugar, and mix until creamy. Add in the vanilla.
Add in your flour and add the milk slowly. You will want to mix until it reaches your desired thickness.

Blue Oreo Frosting

In a clean mixer you will cream your butter, powdered sugar, vanilla, heavy whipping cream, and mix until smooth.
Add in some crushed Oreos, and blue food coloring.

Chocolate Ganache Directions

Using a small pot, pour the heavy whipping cream into it and place onmedium heat.
Pour the chocolate chips into a medium heat safe bowl
Once the heavy whipping cream starts to simmer, remove from heat and pour onto the chocolate chips.
Allow to sit for 1 minute before whisking until smooth
Pour the chocolate ganache into the squeeze bottle

How to Assemble Cookie Monster Cake

Using the squeeze bottle and add chocolate ganache drips around theedge of the cake.
Using the mini chocolate chip cookies, place them around the bottom of the cake.
Next use the blue oreo frosting in the piping bag, pipe dollops along the top of the cake, make sure to leave a space between the dollops.
Place a regular size oreo in between each frosting dollop
Place into the fridge for 1 hour to allow the frosting to harden slightly for easier cutting!
