  • 9-inch springform pan
  • or 9-inch pie plate


For the Cookie Cake

  • 1 ¾ cup all-purpose flour spooned and leveled
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • ¾ cup unsalted butter softened to room temperature, not melted
  • ½ cup brown sugar light or dark
  • ½ cup granulated sugar
  • 1 large egg
  • 1 large egg yolk discard the egg white
  • 2 teaspoons vanilla extract
  • 1 cup chocolate chips

For the Chocolate Buttercream

  • cup unsalted butter softened to room temperature
  • 3 tablespoons cocoa powder
  • 1 - 1 ½ cups powdered sugar
  • ¼ teaspoon salt
  • 1-2 tablespoons heavy cream or milk


Cookie Cake

  • Preheat the oven to 350F (180C or 160C fan-forced) degrees. 
  • Lightly grease the bottom and sides of a 9-inch springform pan. Line the bottom with a round of parchment paper. Or lightly grease a 9-inch pie plate.
  • In a large bowl whisk together the flour, baking soda, and salt.
  • In a separate large bowl beat together the butter and sugars on medium speed until light and fluffy - about 2 minutes.
  • Beat in the egg, egg yolk and vanilla extract.
  • With the mixer on a low speed, beat in the flour mixture about ½ at a time until combined.
  • Turn off the mixer and stir in the chocolate chips. 
  • Spoon the mixture into your prepared pan and spread the dough into an even layer. If you're using a springform pan, the parchment paper may slide around a bit.
  • Bake for about 25-30 minutes until the top looks set. If the top starts to get too brown before the cake is done, tent a piece of aluminium foil and place it over the top.
  • Remove from the oven. Cool the cake in the pan on a wire rack.

Chocolate Buttercream

  • Once the cookie cake is fully cooled, make the frosting.
  • In a medium bowl beat the butter until fluffy.
  • Mix in the cocoa powder and salt with the mixer on a low speed.
  • Then beat in the powdered sugar about ½ cup at a time, alternating with 1 tablespoon of milk/cream until the right sweetness level is reached. 
  • Transfer the frosting to a piping bag (I used a Wilton 1M tip).
  • If using a springform pan, unclamp the outer ring of the pan. Optionally, remove the cookie cake from the base of the pan and place on a serving plate.
  • Pipe the outer edges of the cake with frosting. Slice with a thin, sharp knife.
