  • For the frosting: You’ll need butter, unsweetened cocoa powder, milk, vanilla, and powdered sugar.

How to Make Texas Sheet Cake Cookies

Mix the melted butter, eggs and cake mix until completely incorporated then use a medium cookie scoop to scoop out the cookies onto a baking sheet lined with parchment paper.

In the meantime, melt the butter in a saucepan, then stir in the cocoa powder. Turn off the heat and add vanilla extract, milk, and powdered sugar. Whisk until smooth and lump-free. Spoon warm frosting onto warm cookies and allow the chocolate frosting to set.

Tips and Variations

  • Easy cleanup. Place the baking sheet or a piece of parchment paper underneath the wire rack with the cookies on them. It’ll catch any drippings of the glaze.
  • Enhanced flavor. Adding a pinch of cinnamon to the cookie dough is a great way to add extra flavor.
  • Add a marshmallow. Right out of the oven add a marshmallow then top with chocolate like these chocolate covered marshmallow cookies!
  • Top the Texas sheet cookies with chopped nuts like walnuts or chopped pecans before the frosting sets.
  • Different cookie flavor. You can use this recipe for any flavor combination you’d make a traditional sheet cake with, try vanilla, peanut butter or even strawberry.
