Nothing is better than homemade chocolate chip cookies, but these Fudge-Stuffed Chocolate Chip Cookie Bars might give them a run for their money. I mean, what’s not to love about two thin layers of chewy chocolate chip cookie sandwiched together with a layer of chocolate fudge?! It goes without saying that these are sublime.
This recipe is remarkably easy to make (and even easier to eat). The chocolate chip cookie portion is simply my go-to cookie cake recipe. I made 1.5x the amount to fill a 9×13” pan and just used regular melted butter instead of browning it, but otherwise it’s the same one bowl, no-mixer recipe I’ve used for years.
The fudge is even easier than the cookie dough! Simply melt some dark chocolate in the microwave and then stir in a can of sweetened condensed milk. The mixture will be very thick and fudgy (because it’s fudge, duh). If you were to spread it in a square pan and let it cool, you could slice it into pieces and eat it as is, but today it’s going between two layers of cookie dough and being baked to chewy, chocolaty perfection.
Fudge-Stuffed Chocolate Chip Cookie Bars only need 30 minutes in the oven—it’s the cooling step that takes a while! It will be worth it though because you’ll get chewy cookie, soft fudge and perfectly clean edges. Who can resist these layers?! Not me. That’s for damn sure.
Fudge-Stuffed Chocolate Chip Cookie Bars
makes one 9x13-inch pan, 24-30 bars
3 cups all-purpose flour
3 tablespoons cornstarch
1 1/2 teaspoon baking soda
1 teaspoon Kosher or sea salt
18 tablespoons (2 sticks + 2 tablespoons) unsalted butter, melted
1 1/2 cups light or dark brown sugar, packed
2 large eggs, room temperature
2 teaspoons pure vanilla extract
1 1/2 cup semisweet chocolate chips
12 ounces chopped dark chocolate
1 14-ounce can sweetened condensed milk
Preheat oven to 350F. Grease a 9x13-inch pan. Line with parchment, leaving overhang on the long sides for removal, and grease again. Set aside.
Make the cookie dough. In a medium mixing bowl, whisk together flour, cornstarch, baking soda, and salt. Set aside.
In a large mixing bowl, whisk together melted butter and brown sugar. Mix in eggs one at a time, followed by vanilla. Add dry ingredients in two installments, stirring to combine. Fold in chocolate chips.
Transfer half the dough to prepared pan and spread/press into one even layer.
Make the fudge. Place dark chocolate in a microwave safe bowl. Microwave in 30 second increments, stirring between, until melted and smooth. Whisk in sweetened condensed milk. Mixture will be thick.
Use an offset icing spatula or the back of a spoon to spread fudge over the layer of cookie dough, making sure to go all the way to the edges. Use your hands to press the remaining dough into an even layer over the top of the fudge; this is easiest if you work with a little bit at a time and patch it together.
Bake 25-30 minutes, until the top no longer appears shiny.
Let cookie bars cool completely in the pan on a rack. Use the parchment overhang to remove to a cutting board. Discard parchment. Use a large sharp chef’s knife to slice bars. Serve.
Decorated cake will keep in an airtight container at room temperature for up to five days.
