Substitutions and Additions

  • Choose Your Cake: Although this recipe calls for a white or yellow cake mix, you can use a chocolate cake mix, a brownie mix, or any flavor cake mix you prefer. Feel free to forgo the box and bake a homemade cake or make it even easier and buy a cake at the store.
  • Create An Ice Cream Cake: Instead of using the homemade blue frosting in this recipe, try making my Cookie Monster Ice Cream and layering it between the cake and cookies.
  • Customize Your Cake In A Jar: Feel free to experiment with your favorite cake and frosting combinations. While it may not look like a Cookie Monster dessert, it can be customized to appear festive for various holidays and celebrations.

  1. Make The Cookie Monster Frosting: Mix together the butter and shortening until smooth. Add powdered sugar and vanilla and mix to combine. Add in the remaining powdered sugar, the milk or coffee creamer, and the gel food coloring. Beat for 2-3 mins.
    Pro Tip: Use a spoon to test the silkiness of the frosting. If it’s not smooth, add in one more tbsp liquid, then beat on medium-high for 4-5 more minutes. You want a fluffy and easy to pipe frosting.
  2. Bake The Cake: Bake the cake according to the directions on the box but add the chopped Oreos to the batter before pouring it into the pan. Cool before assembling.
  3. Assemble: Add 1-2 scoops of cake into the mason jar, push it down, and pipe frosting on top. Cover with a layer of chopped chocolate chip cookies and chopped Oreo cookies. Add another scoop of cake, followed by frosting, then cookies. Repeat once more if there is space, ending with frosting.
  4. Make The Cookie Monster: Add two candy eyeballs and half a chocolate chip cookie for a mouth.
  5. Serve: Serve and enjoy!

Frequently Asked Questions

Can I freeze My Cookie Monster Desserts?

Yes, you can freeze these desserts. Keep in mind that as they thaw they will change consistency slightly. Keep them in the freezer, tightly covered, for up to 2 months.

How Many Servings Does This Recipe Make?

The tall mason jars that I use for this recipe are 16 oz, which is the equivalent of about 4 servings per jar. This can absolutely be made in smaller jars for parties and gatherings by following the same steps.

Do I Need To Use Both Blue Gel Colors For My Frosting?

I find that the electric blue gel color is quite bright. I added the royal blue color to darken it a bit. Feel free to experiment until you get the color you like.

Will My Mouth And Hands Turn Blue From the Frosting?

Your mouth, teeth, and hands will probably turn blue! However, it will easily wash away with soap and water.
