A cookie cake that’s loaded with chocolate chips, Crunch chocolate, and my favorite, M&Ms! This cookie cake can be made using any of your favorite chocolate or with just chocolate chips! It’s the perfect treat to serve with vanilla ice cream or a little whipped cream!
I mean, we’re talking THICK and CHOCOLATEY. A cookie cake is the perfect way to use up leftover Halloween candy. Or it’s the perfect excuse to buy Halloween candy?
This cookie cake is all of my chocolate dreams come true and then some.
There’s something you should know. I always underbake. On purpose. Because underbaking is like eating cookie dough and cookies at the same time. Which is the perfect way to have your cake and eat it too. It’s probably on the list of top 5 best things on the planet. Speaking of which, this cookie cake is probably on that list too. It’s absolutely perfectly browned with crisp edges and the center is soft and chewy and just barely underbaked. Mmm.

Lucky for all of us (but probably not our pants) this cookie cake is ridiculously dangerously easy to make. We’re making a quick cookie dough and studding it with our favorite Halloween chocolate. I used chocolate chips, mini M&Ms (I prefer them to the regular ones), and chopped up Crunch chocolate. You can use whatever you like. Butterfingers, Twix, Snickers, and even Reeses! The possibilities are endless. A soft baked center, crunchy-chewy edges, and studs of chocolate everywhere.

Today’s cookie cake recipe uses enough cookie dough to bake, oh i’d say, about 2 dozen cookies. So, I don’t suggest eating the entire cake on your own. Although, it’s kind of hard to resist. (I’m talking major, major self control here.)

Feel free to top with a simple chocolate buttercream frosting or even a meringue frosting, like the one used here.
I served my simple without any of the frills.
We’ve stuffed chocolate and cookies into a cake. Can there be a more perfect dessert? Oh and I like my cookie cake with just a tall glass of ice cold milk. Just a little serving suggestion 😉

Loaded Chewy Chocolate Chip M&M Cookie Cake
Ingredients
- 12 tablespoons 3/4 cup salted butter
- 3/4 cup light brown sugar
- 1/4 cup granulated sugar
- 1 large egg room temperature
- 1 egg yolk room temperature
- 2 cups all-purpose flour
- 2 teaspoons baking powder
- 1 tablespoon vanilla extract
- 3/4 cup chopped chocolate I used m&ms and Crunch bars, divided*
- 1/2 cup chocolate chips (use white chocolate semi sweet, or bittersweet, divided
Instructions
- Position a rack near the lower third of the oven and preheat the oven to 350 degrees F. Spray a 9-inch pie dish (or cake pan) with nonstick cooking spray. Set aside.
- In a medium bowl, combine the flour and baking powder. Set aside.
- In the bowl of an electric mixer, fitted with the paddle attachment, beat the butter for 2 minutes on medium speed until completely smooth and creamy. Add the brown sugar and the granulated sugar and continue to beat on medium speed until creamy, about 1 minute. Add in the egg, egg yolk, and vanilla on medium speed until just combined. Stop the mixer, scrape down the side and bottom of the bowl. On the low speed setting, slowly mix in the dry ingredients until just combined. Stop the mixer, using a rubber spatula, fold in 1/2 cup of the chopped candy bars along with most of the chocolate chips (reserving about 1 - 2 tablespoons for the topping).
- Press the cookie dough evenly into the prepared pie dish. Top the cookie cake batter with the remaining 1/4 cup of chopped candy bars and the 2 tablespoons of chocolate chips. Bake for 25 - 30 minutes or until the cake is lightly golden brown (could be up to 35 minutes depending on your oven). Cover the cake loosely with aluminum foil after the first 15 minutes of baking to avoid excess browning. Remove from the oven and set the pie dish on a wire rack to allow cookie cake to cool completely. Use a sharp knife to slice, once cooled.
Notes
- The kind of chocolate you use is completely up to you. I used mini m&ms and chopped up Crunch candy Bars. Feel free to use Snickers, Twix, Cookies n' Cream bars, Milky Ways, or even Reese's Peanut Butter Cups.
- Cookie cake batter can be made 24 hours in advance and kept in the refrigerator until ready to bake. Allow the cookie cake mixture to sit on the counter for 10 minutes prior to baking.
- Cookie cake can be topped with chocolate buttercream or a vanilla meringue frosting if desired.
