This Texas sheet cake cookies recipe takes everything I love about rich chocolate cake and turns it into a soft, fudgy cookie topped with the most delicious frosting ever. That crackly top gives them a bakery style look, and when a chocolate craving hits, this is the chocolate cookie recipe that I reach for!

One of my favorite parts of this recipe is pouring the warm chocolate frosting over the cookies and watching it harden on top – it is just so satifsying! These cookies stay soft in the center with that shiny finish on top. Every time I make a batch, they disappear fast, which tells me I should probably double the recipe next time.

Ingredients Notes

For the Cookies
- Chocolate cake mix: You can also use devil’s food cake mix for a richer flavor or German chocolate cake mix for a lighter chocolate taste
- Eggs
- Vegetable oil: You can substitute melted butter for a more buttery flavor, though the cookies will be slightly denser
For the Frosting
- Unsalted butter: You can use salted butter if needed and adjust to taste
- Cocoa powder: Natural cocoa works best, but Dutch process will give a deeper chocolate flavor
- Milk: Can be substituted with almond or oat milk for a dairy-free option, or replace a small amount with buttermilk for a slightly tangy, extra-soft cookie
- Vanilla extract: Adds warmth and balances the chocolate flavor
- Powdered sugar

How to Make Texas Sheet Cake Cookies
- Prepare the oven: Preheat to 350°F and line a baking sheet with parchment paper or a silicone baking mat.
- Mix the dough: In a large bowl, combine the chocolate cake mix, eggs, and vegetable oil. Stir until a thick, sticky dough forms with no dry spots or lumps.

- Bake: Scoop the dough onto the prepared cookie sheet, spacing cookies about 2 inches apart. Bake for 8 to 10 minutes until the edges are set but the centers are still soft.

- Make the frosting: In a saucepan over medium heat, melt the butter. Whisk in the cocoa powder and milk until smooth, then remove from heat. Stir in the vanilla and powdered sugar until glossy.

- Frost: Let the cookies cool for 2 to 3 minutes, then spoon the warm frosting over each cookie and gently spread toward the edges.

- Cool and serve: Transfer the cookies to a wire rack and allow the frosting to set before serving.

Make Ahead & Storage Instructions
- Room temperature: Store the cookies in an airtight container for up to 3 days. If stacking, place a layer of wax paper between cookies to protect the frosting.
- Make ahead: You can bake the cookies up to a day in advance and add the frosting just before serving to keep them looking fresh and soft.
- Freezing: Baked, unfrosted cookies freeze well for up to 3 months. Thaw them at room temperature and frost just before enjoying for the best texture and appearance.

For the Frosting:
- ½ cup 1 stick unsalted butter
- 2 tablespoons cocoa powder
- 3 tablespoons milk
- 1 teaspoon vanilla extract
- 2½ cups powdered sugar
Instructions
- Preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper or a silicone baking mat to prevent sticking.
- In a large mixing bowl, combine the chocolate cake mix, eggs, and vegetable oil. Stir everything together until a thick dough forms and no dry pockets of cake mix remain. The dough will be sticky.1 13.25 ounces 1 box chocolate cake mix, 2 large eggs, ⅓ cup vegetable oil
- Use a cookie scoop or a spoon to drop rounded balls of dough onto the prepared baking sheet, spacing them about 2 inches apart to allow for spreading.
- Bake the cookies for 8 to 10 minutes. The edges should look set, but the centers might still look slightly soft. Do not overbake them, as they will firm up while cooling.
- While the cookies are baking, make the frosting. In a medium saucepan over medium heat, melt the butter. Once melted, whisk in the cocoa powder and milk until smooth. Remove the pan from the heat.½ cup 1 stick unsalted butter, 2 tablespoons cocoa powder, 3 tablespoons milk
- Stir the vanilla extract and powdered sugar into the chocolate mixture. Whisk vigorously until the frosting is smooth and glossy. If it seems too thick, add another splash of milk, if it is too thin, add a bit more powdered sugar.1 teaspoon vanilla extract, 2½ cups powdered sugar
- Let the cookies cool on the baking sheet for about 2-3 minutes after removing them from the oven. While they are still warm, spoon about a tablespoon of the warm frosting onto the center of each cookie, gently spreading it toward the edges.
- Transfer the frosted cookies to a wire rack to cool completely. The frosting will set and harden slightly as it cools. Enjoy!
Jenn’s Notes
- Store: Keep cookies in an airtight container at room temperature for up to 3 days. Place wax paper between layers to protect the frosting.
- Make ahead: Bake cookies up to 24 hours in advance and frost the day of serving for best texture and appearance.
- Freeze: Freeze baked unfrosted cookies for up to 3 months. Thaw at room temperature and frost fresh before serving.
- Do not overbake or the cookies will lose their soft cake like texture
- Frosting the cookies while warm helps the icing spread smoothly and set properly
- If frosting thickens too quickly gently rewarm it over low heat
- Using a cookie scoop helps cookies bake evenly












These were very easy and delicious, however mine were not as pretty as yours, my dough was stiff and stayed in mounds with very little spread while baking. Wondering what you think would be the problem.
Totally get this. Cookie dough can be sneaky like that. Here are the most common reasons this happens and what to check next time. Easy fixes, promise.
• Too much flour. Even a little extra can make the dough stiff. Spoon flour into the measuring cup and level it off instead of scooping straight from the bag.
• Butter too cold. If the butter was not soft enough, it can keep the dough from spreading. It should be soft but not melty.
• Dough chilled too long. If the dough sat in the fridge for a while, it will bake up thicker. Let it sit at room temp for 10 to 15 minutes before baking.
• Baking sheet temp. If you reused a warm pan, cookies can bake unevenly. Always start with a cool pan.
The cookies will still taste great, even if they stay puffier. If you want more spread next time, gently flatten the dough balls before baking.
So glad you loved them, and thanks for baking along with me.
