For the Cake:

  • 1 box white or vanilla cake mix (plus ingredients listed on the box)
  • 10 chopped Oreos

For the Blue Cookie Monster Frosting:

  • 1/2 cup (1 stick) unsalted butter, room temperature
  • 1/2 cup vegetable shortening
  • 3 cups powdered sugar
  • 2 tablespoons milk or coffee creamer
  • 1 teaspoon vanilla extract
  • 1 drop electric blue Americolor gel color
  • 2 drops royal blue Chef Masters gel color

For the Jar Layers:

  • 8-10 chopped Oreos
  • 8-10 chopped chocolate chip cookies (any brand)
  • 8 candy eyes
  • 2 chocolate chip cookies, cut in half


Bake the Cake:

  1. Follow the instructions on the cake mix box to prepare the batter. Fold in about half of the chopped Oreos.
  2. Bake as directed and let cool for 30 minutes.

Make the Frosting:

  1. In a mixing bowl, add butter and shortening. Mix until smooth.
  2. Add one cup of powdered sugar and the vanilla. Mix until fully combined, starting on low speed and increasing to medium.
  3. Add the remaining two cups of powdered sugar, the milk or coffee creamer, and the gel food coloring. Mix on low speed, gradually increasing to high, and beat for 2-3 minutes.
  4. Test the frosting for silkiness with a spoon. If not smooth, add one more tablespoon of milk and beat on medium-high for 4-5 more minutes to create a fluffy, easy-to-pipe frosting.

Assemble the Cake Jars:

  1. Add frosting to a piping bag fitted with a 1M tip.
  2. Add 1-2 scoops of cake into each mason jar and use the scooper to press it down.
  3. Pipe frosting on top of the cake layer. Add chopped chocolate chip cookies and chopped Oreo cookies.
  4. Repeat layers: another scoop of cake, frosting, then cookies. Repeat once more if there’s space, ending with frosting.
  5. Decorate each jar with two candy eyeballs and half a chocolate chip cookie to resemble Cookie Monster.

Serve and Enjoy:

  1. Serve immediately or store in the refrigerator for 3-4 days. Bring to room temperature before serving.
  2. These desserts can also be frozen, covered tightly, for up to 2 months.
