Celebrate Halloween by serving a festively decorated Halloween Cookie Cake to your party guests. This thick and chewy cookie cake is packed with ooey-gooey semi-sweet chocolate chips and neon green, purple, and orange Mad Scientist M&M’s.
If you are hosting a Halloween party with lots of hungry guests, sharing a fun Halloween gift with a friend, or making a delicious Halloween dessert for your family, this recipe is for you.
Cookie cakes are easy to make and decorate and this one is packed with chocolate chips and M&M’s.
The cookie recipe is simple and can be made using a bowl and spoon. No mixer is needed.
Chocolate chip and M&M Cookie Cake
You’ll stir together all the ingredients in a mixing bowl using a spoon or silicone spatula (my preference. I particularly love my Sprinkle Spatulas. They are so colorful and fun!)
Then, you will add some chocolate chips and brightly colored, neon green, purple, and orange Halloween M&M’s Mad Scientist Mix into the cookie dough. The bag of Mad Scientist M&M candies contains a mix of plain Milk Chocolate M&M’s, Peanut M&M’s, and Peanut Butter M&M’s.
I love how the variety of M&M’s adds more flavor and texture to this cookie cake but you can use plain milk chocolate Halloween Ghoul’s Mix M&M’s instead if that’s all you can find.
Decorating your Halloween Cookie Cake
Before baking the cake, I like to sprinkle more chocolate chips and M&M’s on top of the cookie dough so that they show up on the top of the cookie once it is baked.
Once the cookie cake is cooled, you can decorate it using frosting and even more M&M’s or you can simply serve it as it is. It tastes and looks great on its own but is fun to decorate.
Use homemade frosting (recipe below) or to make it easier, use tubs of store-bought frosting. To make orange frosting color vanilla (white) frosting using orange food coloring. Making black frosting is easier when you start with chocolate frosting and add the black food coloring.
Of course, you could use any colors that you like to add a design to the top of your cookie cake.
I piped an orange and black border around the outside of my cookie cake, then I added the phrase “Happy Halloween” along with a fuzzy black spider to the center of the cake.
My exchange student, Matilde, had fun decorating her Halloween cake with candy eyes inside the word “Boo” and an orange and black bug.
Both of us added some milk chocolate M&M’s around the frosting border. I love how the border incorporates the orange, black, neon green, and purple colors.
Get creative and add your own unique design to the top of your giant cookie.
