4.5 from 107 reviews

Texas Sheet Cake Cookies are a delicious twist on the classic Texas sheet cake, featuring moist, cake-like chocolate cookies topped with a rich, glossy chocolate frosting. These cookies are quick and easy to make using a boxed cake mix, making them perfect for a speedy dessert that doesn’t sacrifice flavor or texture.

Ingredients

Scale

For the Cookies:

  • 1 box (13.25 ounces) chocolate cake mix
  • 2 large eggs
  • ⅓ cup vegetable oil

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

  1. Preheat and Prepare Baking Sheet: Preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper or a silicone baking mat to prevent sticking and ensure easy removal of cookies.
  2. Mix Cookie Dough: In a large mixing bowl, combine the chocolate cake mix, eggs, and vegetable oil. Stir everything together until a thick, sticky dough forms with no dry pockets of cake mix.
  3. Scoop Dough onto Baking Sheet: Use a cookie scoop or spoon to drop rounded balls of dough onto the prepared baking sheet. Space them about 2 inches apart to allow for spreading during baking.
  4. Bake Cookies: Bake the cookies for 8 to 10 minutes. The edges should look set while the centers remain slightly soft. Avoid overbaking to retain the soft, cake-like texture.
  5. Make the Frosting: While the cookies bake, melt the butter in a medium saucepan over medium heat. Whisk in the cocoa powder and milk until the mixture is smooth. Remove from heat.
  6. Finish Frosting: Stir in the vanilla extract and powdered sugar. Whisk vigorously until the frosting is smooth and glossy. Adjust consistency by adding a splash of milk if too thick or more powdered sugar if too thin.
  7. Frost Warm Cookies: Let cookies cool on the baking sheet for 2-3 minutes after baking. While still warm, spoon about a tablespoon of frosting onto each cookie and gently spread it towards the edges.
  8. Cool and Set: Transfer the frosted cookies to a wire rack to cool completely. The frosting will harden slightly as it sets, creating a delectable finish.

Notes

  • Store cookies in an airtight container at room temperature for up to 3 days; place wax paper between layers to protect the frosting.
  • For best texture, bake cookies up to 24 hours in advance and frost on the day of serving.
  • Freeze unfrosted baked cookies for up to 3 months; thaw at room temperature and frost fresh before serving.
  • Do not overbake to preserve the soft, cake-like texture of the cookies.
  • Frosting cookies while warm helps it spread smoothly and set properly.
  • If frosting thickens too quickly, gently rewarm it over low heat to restore consistency.
  • Using a cookie scoop ensures evenly sized cookies that bake uniformly.
