With delicious candy toppings and spiderweb icing, this chocolate chip Halloween Giant Cookie Cake is the perfect mix of spooky and sweet!
Over the years, we’ve had many birthday parties with this Perfect Giant Cookie Cake as the centerpiece, rather than a traditional birthday cake.
The chocolate chip cookie base is perfectly crispy on the bottom and around the edges, while the center stays soft and chewy. Topped with ice cream, it’s the perfect dessert in my opinion.
This year, I decided it would be fun to use that same giant cookie cake recipe base but create different holiday versions. So today I’m sharing how to create a cute Halloween Giant Cookie Cake.
For the cookie base:
- baking soda
- butter (or half butter, half shortening)
- brown sugar
- granulated sugar
- semi-sweet chocolate chips
- chocolate candies
For the decoration on top:
- Oreo pie crust (or very finely crushed Oreo cookies)
- vanilla frosting
- various Halloween candies like candy corn, candy eyes, sprinkles, etc.
I typically use a regular sized bag of plain M&M’s for our birthday cake cookie. It adds a fun pop of color. For this Halloween cookie cake, you could get Halloween M&M’s. If you do, you’ll want to add them to the top (they don’t really show inside the giant cookie.)
How to make the giant cookie base
Start by mixing together the dry ingredients. Set aside. In another bowl, cream together the sugars, butter and shortening. Add the eggs and vanilla and beat together.
After the batter is mixed, add the dry ingredients and mix just until blended. Fold in the chocolate chips.
Line a 12″ pizza pan with parchment paper and then press the batter onto the pan. Try to get it evenly spread around the pan. Be sure to leave space around the edges for spreading.
Press the chocolate candies into the top of the batter. Bake until golden brown around the edges.
How to decorate the Halloween Giant Cookie Cake
For the decoration on top, start with a very thin layer of icing on top of the giant cookie. Make sure it’s completely cooled first!
Next, break apart the Oreo pie crust (it’s perfect because the cookie “dust” is so fine) and spread it evenly across the icing. This will help it to stick in place. Add any sprinkles or candies to the top.
Then, use a piping bag or small plastic bag with a hole snipped in the corner and pipe frosting in a web design. Start with the wider lines and then add detail with a smaller tip.
Slice with a pizza slicer and serve!
