Ingredients
- Cookies:
- 1 15.25oz. box chocolate cake mix
- 2 large eggs
- 1/3 cup oil
- Icing:
- 2 Tbsp. unsweetened cocoa powder
- 1/2 cup unsalted butter
- 3 Tbsp. milk
- 2 cups confectioners sugar
Instructions
- Step 1: Preheat your oven to 350 degrees F and line a baking sheet with parchment paper to prevent sticking.
- Step 2: In a large bowl, mix together the chocolate cake mix, eggs, and oil until the batter is smooth and well combined.
- Step 3: Roll heaping tablespoons of dough into balls and place them about 2 inches apart on the prepared baking sheet.
- Step 4: Bake the cookies for 8 minutes or until they are set but still soft to the touch.
- Step 5: Let the cookies cool on the baking sheet for 2-3 minutes before transferring them to a wire cooling rack to cool completely.
- Step 6: For the icing, melt the butter, cocoa powder, and milk together in a medium saucepan over medium heat, whisking until smooth.
- Step 7: Remove the saucepan from heat and gradually whisk in the confectioners sugar until the icing is smooth and fully combined.
- Step 8: Place a baking sheet under the wire rack holding the cookies to catch drips, then spoon the chocolate buttercream over each cookie until covered.
- Step 9: Allow the icing to set before serving or storing the cookies.
Tips & Variations
- For extra moist cookies, try adding a teaspoon of sour cream to the dough before baking.
- If you prefer a richer chocolate flavor, use Dutch-process cocoa powder in the icing.
- Decorate the icing with a sprinkle of sea salt or chopped nuts for added texture and flavor.
- Make mini versions by using a teaspoon-sized dough ball and reducing baking time by 2-3 minutes.
Storage
Store the cookies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate and allow them to come to room temperature before serving. If the icing firms too much when chilled, soften slightly by microwaving the cookies for a few seconds.

FAQs
Can I use a different cake mix flavor?
Yes, you can experiment with other cake mix flavors like devil’s food or even a spice cake for a unique twist, but chocolate mix works best to keep the classic Texas sheet cake taste.
Can I make the icing ahead of time?
Absolutely! Prepare the icing in advance and store it in the refrigerator. Rewarm gently over low heat or in the microwave before spreading it on the cookies to keep it smooth and spreadable.
