How To Make Cookie Monster Cupcakes

We highly recommend making the homemade cookie cupcake batter, but feel free to speed things up by using a box cake mix.

Preheat 350 degrees and line cupcake pan with cupcake liners.
Cream together the butter and sugar and then add the egg until light and fluffy. Mix in the milk, vanilla and oil.
In a large bowl mix together the flour, salt and baking powder.
Gradually add the dry ingredients to the wet ingredients.
Fold in the chocolate chips and crushed Oreos.
Fill the cupcake liners (in the muffin cups) 2/3 full and bake for bake for 21 minutes or until a toothpick comes out clean

Frosting and Decorating

Using a hand mixer, combine all ingredients in a bowl and mix on medium speed.
Stir in a few drops of the blue coloring.
Spoon the frosting into the piping bag or baggie with the corner snipped off and frost the cooled cupcakes to look like cookie monster’s fur.

Place candy eyes onto the top of the frosting.
Using a small paring knife, cut the chocolate chip cookie in half and press the flat side into the bottom corner.

Tips and Variations

If you’re planning for a Cookie Monster or Sesame Street party and find yourself in a pinch, you can always use any flavor of boxed cake mix and add the toppings.
Make mini cupcakes (adjusting the baking time) and use cookie crisp cereal instead of the mini cookies.
Add blue sprinkle on top like jimmies to look more like cookie monster hair.
If you do not have candy eyes, use marshmallows and add dots of chocolate frosting for the pupils.
