Ingredients
Scale
- For the Soft Chocolate Cookies:
- 1 box (15.25 oz / 432 g) chocolate cake mix (Devil’s Food or Swiss Chocolate)
- 2 large eggs, room temperature, lightly beaten
- 1/3 cup (80 ml) vegetable oil or canola oil
- For the Warm Chocolate Sheet Cake Frosting:
- 1/2 cup (1 stick / 113 g) unsalted butter
- 2 tbsp unsweetened Dutch-process cocoa powder
- 3 tbsp whole milk
- 2 1/2 cups (300 g) powdered sugar, sifted
- Optional Topping:
- 1/4 cup (30 g) pecans, finely chopped and toasted
Instructions
- Preheat Oven and Prepare Pans: Preheat your oven to 350°F (175°C) and line two large baking sheets with parchment paper.
- Mix Chocolate Cookie Dough: In a large mixing bowl, combine the entire box of chocolate cake mix, 2 lightly beaten room-temperature eggs, and 1/3 cup (80 ml) of vegetable oil or canola oil. Stir with a wooden spoon or rubber spatula until all the ingredients are fully incorporated and a thick, soft chocolate cookie dough forms.
- Portion Cookie Dough: Using a medium cookie scoop or tablespoon, divide the chocolate cookie dough into 16 portions, approximately 40 g each. Arrange the portions on the prepared baking sheets, leaving about 2 inches of space between each cookie to allow for spreading.
- Bake Until Edges Are Set: Bake the chocolate cake mix cookies at 350°F (175°C) for 7–8 minutes, or until the outer edges are set while the centers remain slightly soft and puffed. Avoid overbaking to preserve their wonderfully tender, fudgy texture.
- Cool Cookies Completely: Remove the baking sheets from the oven and allow the cookies to rest on the warm pans for 4–5 minutes so the centers can finish setting. Carefully transfer the cookies to a wire cooling rack and let them cool completely before adding the chocolate frosting.
- Cook Warm Cocoa Frosting Base: In a small saucepan over medium heat, combine 1/2 cup (113 g) of unsalted butter, 2 tablespoons of unsweetened Dutch-process cocoa powder, and 3 tablespoons of whole milk. Whisk constantly as the butter melts until the mixture becomes smooth and reaches a gentle simmer.
- Whisk in Powdered Sugar: Immediately remove the saucepan from the heat. Gradually add 2 1/2 cups (300 g) of sifted powdered sugar, whisking continuously until the chocolate frosting becomes perfectly smooth, glossy, and free of lumps.
- Frost, Decorate, and Set: While the chocolate frosting is still warm and pourable, spoon generous dollops over each completely cooled chocolate cookie. Gently spread the frosting toward the edges to create a beautiful, smooth chocolate coating. If desired, immediately sprinkle the tops with 1/4 cup (30 g) of finely chopped, toasted pecans before the frosting begins to set. Allow the cookies to rest at room temperature until the frosting firms into a glossy, fudgy shell before serving!
Notes
- Pour Frosting While Warm: Apply the chocolate frosting while it is still warm so it spreads smoothly across the cookies and sets into the signature shiny Texas sheet cake coating. If the frosting thickens in the saucepan while you work, gently rewarm it over low heat for approximately 30 seconds, stirring continuously until pourable again.
- Stick to the 7–8 Minute Bake Time: Chocolate cake mix cookies can become dry if baked too long. Remove them when the edges are just set and the centers still look slightly soft. The residual heat from the baking sheets will finish setting the cookies while keeping their centers tender and fudgy.
- Toast the Pecans: For an extra-delicious nutty topping, toast the finely chopped pecans in a dry skillet over medium heat for approximately 3 minutes until fragrant. Allow them to cool slightly, then sprinkle them over the warm chocolate frosting before it sets.
