Ingredients:
Baking the Cake
The first step to creating our Cookie Monster masterpiece is to bake the cake. Follow the instructions on your 15 oz box of white or vanilla cake mix precisely. This usually involves combining the cake mix with eggs, oil, and water. Make sure your ingredients are at room temperature as this helps ensure a smoother batter and a more even bake. Preheat your oven according to the cake mix box directions. For these cake jars, I prefer to bake the cake in a rectangular baking pan, like a 9×13 inch pan. This makes it easier to cut out uniform pieces later. Grease and flour your pan well, or use parchment paper for easy removal. Bake the cake until a toothpick inserted into the center comes out clean. Once baked, let the cake cool in the pan for about 10-15 minutes before inverting it onto a wire rack to cool completely. It’s crucial that the cake is entirely cool before you start assembling the jars, otherwise, the frosting will melt and you’ll end up with a soggy mess.
Making the Cookie Monster Frosting
Now for the fun part – creating our vibrant Cookie Monster blue frosting! In a large bowl, cream together the ½ cup (1 stick) of softened unsalted butter and ½ cup of vegetable shortening until light and fluffy. Using both butter and shortening creates a frosting that is stable and has a wonderful texture. Gradually add the 3 cups of powdered sugar, ½ cup at a time, mixing on low speed until just combined. Don’t overmix at this stage, or your frosting can become too stiff. Once all the powdered sugar is incorporated, add the 1 teaspoon of vanilla extract. Now, it’s time for the color. Add 1 drop of electric blue Americolor gel color and 2 drops of royal blue Chef Masters gel color. Gel colors are highly concentrated, so start with a small amount. Mix thoroughly until you achieve a beautiful, consistent Cookie Monster blue. If the frosting is too thick, add the milk or coffee creamer 1 tablespoon at a time until you reach your desired consistency. You’re aiming for a smooth, spreadable frosting that holds its shape. Taste it and adjust sweetness if needed.
Assembling the Cake Jars
This is where your creativity truly shines! You’ll need 4-6 small jars or glasses for this recipe. Begin extract by cutting out rounds of your cooled cake using a cookie cutter that is slightly smaller than the diameter of your jars. Alternatively, you can simply crum extractble the cake into bite-sized pieces if you prefer a more rustic look.
Step 1: Layer the Cake Crum extractble
Start by placing a generous layer of crum extractbled cake at the bottom of each jar. Don’t be shy; we want a good cake base. Gently press it down slightly to create a stable foundation.
Step 2: Add Cookie Goodness
Sprinkle a layer of the chopped Oreos and chopped chocolate chip cookies over the cake crum extractble. This adds that essential cookie crunch and flavor that Cookie Monster adores.
Step 3: Frosting Time!
Add a dollop of your vibrant blue Cookie Monster frosting over the cookie layer. Use a spoon or a piping bag to spread it evenly. Aim for a good layer that covers the cookies and cake underneath.
Step 4: More Cake and Cookies
Repeat the layering process: another layer of cake crum extractble, followed by another generous scattering of chopped Oreos and chocolate chip cookies.
Step 5: Top it Off
Finish each jar with a final, beautiful swirl of Cookie Monster frosting. Now, it’s time for the iconic Cookie Monster details. Carefully place two candy eyes onto the frosting of each jar to give them their signature look. You can also add a bit of a cookie crum extractb border around the edge of the frosting. For an extra special touch, if you have them, you can place one of the halved chocolate chip cookies on top, as if Cookie Monster is about to take a bite! If you’re making these for a special occasion, tie a blue ribbon around the neck of each jar for a festive presentation.
These Cookie Monster Cake Jars are best enjoyed within a day or two, stored in the refrigerator. The flavors meld beautifully as they sit, and the texture of the cake and cookies remains delightful. Enjoy every delicious, blue, cookie-filled bite!

Frequently Asked Questions about Cookie Monster Cake Jars:
Can I make these cake jars ahead of time?
Absolutely! These are fantastic for making ahead. You can bake the cake and prepare the frosting a day or two in advance. Assemble the jars a few hours before serving to ensure the cake stays moist and the frosting is perfectly set. Store them in the refrigerator.
What kind of jars are best for this recipe?
Small canning jars (like 4-ounce or 8-ounce Mason jars) work wonderfully. You can also use any clean glass jars with lids. Ensure they are food-safe and sturdy enough to hold the layers.
Can I use a different cake flavor?
Yes, you can! While vanilla or funfetti are classic choices for this theme, feel free to experiment. A chocolate cake would also be delicious, or even a subtle lemon cake for a brighter flavor profile. Just ensure the cake is moist enough to hold up to the layering.
