This DIY Cookie Cake features a chewy chocolate chip cookie topped with a simple homemade buttercream!


For the cookie:

  • ½ cup unsalted butter
  • ½ cup light brown sugar
  • ¼ cup sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 11/3 cups all-purpose flour
  • ½ teaspoon salt
  • 1/4 teaspoon baking soda
  • ¼ teaspoon baking powder 
  • 1 cup chopped semisweet chocolate chips

For the frosting:

  • 6 tablespoons unsalted butter, at room temperature
  • 11/2 cups powdered sugar
  • 1 teaspoon vanilla extract
  • ½ teaspoon salt
  • 1 tablespoon milk 


  1. Preheat the oven to 350 degrees Fahrenheit and lightly grease an 11” round rimmed baking pan. 
  2. In a small pan over medium heat, gently melt the butter just until melted. Pour the butter into a large mixing bowl with the brown sugar and sugar. Stir until smooth. Add the egg and extract, stirring just until smooth. Add the flour, salt, baking soda, and baking powder, stirring with a spatula until smooth. Fold in the chopped chocolate chips and dump the batter into the prepared pan, pressing gently with your fingers until the dough is spread out evenly. Bake in the preheated oven about 11-12 minutes or until the edges are barely set. The insides will look underdone- do not overbake! Allow to cool completely prior to frosting. 
  3. To frost the cookie cake, combine all of the ingredients in a large bowl. Using a hand mixer, stir on low until combined and then increase the speed to medium to beat to smooth for 2 minutes. Use a 1M piping tip fitted bag to pipe the frosting on the cooled cake prior to enjoying.
