Don’t worry if you’re not a master baker; these jars are all about fun and flavor, and they’re surprisingly easy to assemble. Let’s get baking and layering!
Ingredients:
Baking the Cake
The first step to our Cookie Monster cake jars is to bake the cake. Follow the instructions on your 15 oz box of white or vanilla cake mix precisely. You’ll typically need to add eggs, oil, and water. Preheat your oven and prepare your baking pan(s) as directed. I usually opt for a 9×13 inch baking pan as it’s easy to get a nice, even layer of cake that’s perfect for crum extractbling. Ensure your ingredients are at the right temperature as specified on the box. Once baked, let the cake cool completely in the pan before attempting to remove it. This is crucial for easy handling and preventing it from falling apart.
Preparing the Cake Crum extractbles
Once your cake has cooled entirely, it’s time to turn it into delightful cake crum extractbles. Gently remove the cake from the pan and place it on a clean surface or a large baking sheet. Using your hands or a fork, break the cake into smaller pieces. Then, we’ll process these pieces into crum extractbles. You can do this in batches using a food processor, pulsing until you have a consistency that resembles coarse breadcrum extractbs. Alternatively, if you don’t have a food processor, you can place the cake pieces in a large zip-top bag and gently crush them with a rolling pin or the bottom of a heavy glass. Aim for a mix of fine crum extractbs and slightly larger pieces for texture. This crum extractbled cake will form the base and layers of our jars.
Whipping Up the Cookie Monster Frosting
Now for the star of the show – the vibrant blue Cookie Monster frosting! In a large mixing bowl, cream together the softened unsalted butter and vegetable shortening until light and fluffy. This is best done with an electric mixer. Gradually add the powdered sugar, about a cup at a time, mixing on low speed until incorporated, then increasing the speed. Once all the powdered sugar is added and the mixture is smooth, add the milk or coffee creamer, starting with 2 tablespoons. You want a thick but spreadable consistency; add the third tablespoon only if needed. Stir in the vanilla extract.
Now for the fun part: coloring! 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 these small amounts and mix thoroughly. You can always add more color to achieve your desired shade of Cookie Monster blue. Mix until the color is completely uniform and vibrant. Be patient; it might take a little mixing to get that perfect, playful hue. Taste the frosting – if it’s too sweet for your liking, you can add a tiny pinch of salt to balance it out, though usually the sweetness is part of the charm!
Assembling the Cake Jars
This is where the magic happens! Grab your clean jars (about 8-10 ounce canning jars work perfectly). Start by spooning a layer of your crum extractbled cake into the bottom of each jar. Don’t overfill; leave plenty of room for frosting and other yummy additions. Next, add a generous dollop of your Cookie Monster frosting, spreading it evenly over the cake crum extractbles. Then, sprinkle a layer of your chopped Oreos (from the divided amount) and chopped chocolate chip cookies over the frosting. Repeat the layering process: another layer of cake crum extractbles, followed by more frosting, and then a sprinkle of your mixed cookie crum extractbles. Continue layering until your jars are nearly full, leaving about an inch of space at the top for a final flourish.
Adding the Finishing Touches
To truly bring our Cookie Monster cake jars to life, we need to add those iconic details. On top of your final frosting layer, add a few more chopped Oreos and chocolate chip cookies. Now, carefully place two candy eyes onto the frosting to create Cookie Monster’s signature goofy eyes. For an extra special touch, you can strategically place one of the chocolate chip cookie halves on top, as if Cookie Monster is about to gobble it up! If you’re making these for a party or as gifts, tie a festive blue ribbon around the rim of each jar for an extra decorative element. These jars are best enjoyed within a few days and should be stored in the refrigerator to keep the frosting firm. Enjoy your delightful, edible creations!

Just before assembling, let the frosting come to room temperature and whip it briefly to ensure a smooth consistency. This makes assembling the jars even quicker!
