These rich and chewy fudge cookies are the ultimate indulgent treat! They're filled with a gooey fudge center and studded with chocolate chips for maximum chocolatey flavor. Recipe includes a how-to video!
Prepare the fudge filling first by placing chocolate chips in a heatproof bowl. Place cream in a small saucepan and heat until steaming, then immediately pour over chocolate chips. Cover and let sit for 5 minutes, then stir until chocolate is completely melted and mixture is smooth.
1 cup semisweet chocolate chips, ½ cup heavy cream
Place filling in refrigerator and allow to chill for 30 minutes. Meanwhile, begin preparing your cookie dough.
Cookie Dough
In a large bowl use an electric mixer (or you may use a stand mixer with paddle attachment) to beat together butter and sugars until creamy and well-combined.
1 cup unsalted butter, 1 ¼ cup light brown sugar, ½ cup granulated sugar
Add eggs and vanilla extract and stir well.
1 large egg + 1 large egg yolk, 1 ½ teaspoons vanilla extract
In a separate, medium-sized bowl, whisk together flour, cocoa powder, cornstarch, baking powder, baking soda, and salt.
2 ¼ cups all-purpose flour, ½ cup natural cocoa powder, 1 Tablespoon cornstarch, 1 teaspoon baking powder, ½ teaspoon baking soda, ¾ teaspoon table salt
With mixer on low speed, gradually stir flour mixture into butter mixture until completely combined, then stir in chocolate chips.
1 ½ cups semisweet chocolate chips
Cover dough tightly with plastic wrap and place in refrigerator to chill.
Assembly
Meanwhile, once ganache has mostly solidified, remove from refrigerator. Line a baking sheet with wax paper and drop ganache by 2 teaspoon-sized dollops onto prepared baking sheet.
Place baking sheet in freezer and allow ganache to freeze for at least 15 minutes.
Meanwhile, preheat oven to 350F (175C) and line a baking sheet with parchment paper. Set aside.
Once ganache has frozen enough to be manageable/easy to pick up, remove cookie dough from the fridge and scoop by heaping 1 ½ Tablespoon-sized scoop. Use your thumb to make an indent in the center then remove a ganache dollop from the freezer and insert it into the center of the cookie (you want the ganache to stay cold, so I work in batches and keep what I can in the freezer while I’m waiting for the first batch to cook). Use your hands to cover the ganache dollop with the dough and roll the dough into a smooth ball. Place on baking sheet and repeat with remaining dough, spacing cookies at least 2” apart.
Transfer to 350F (175C) preheated oven and bake for 12-13 minutes. Allow cookies to cool completely on baking sheet before enjoying, keep in mind they will be fragile while warm and, before cooled completely, the fudge filling will be molten and could burn.

Notes
Cocoa powder
You may substitute Dutch process cocoa for this recipe, but natural was my preference for the best flavor for the cookies.
