The dough will be thick like cookie dough, rather than thin like cake batter.

Store the frosting in the fridge, but bring it to room temperature before you want to use it.


For the cookie cake

  • sticks unsalted butter, at room temperature
  • 1 Cup packed light brown sugar
  • 1 whole egg plus 1 yolk
  • 2 Teaspoons vanilla extract
  • 1 Cup all-purpose flour
  • 1 Cup whole-wheat flour
  • 2 Teaspoons cornstarch
  • 1 Teaspoon baking soda
  • 1 Teaspoon salt
  • 1 Cup semi-sweet chocolate chips
  • ½ Cup chopped walnuts

For the chocolate-coffee frosting

  • 2½ Tablespoons heavy cream
  • 1 Teaspoon espresso powder
  • 1 Teaspoon vanilla extract
  • Pinch of salt
  • 1¾ Cup confectioners sugar
  • ¼ Cup unsweetened cocoa powder
  • 1 stick unsalted butter, at room temperature


For the cookie cake

Preheat the oven to 350 degrees F. Line a 9-inch cake pan with parchment paper or spray with nonstick cooking spray.

In the bowl of a stand mixer fitted with a paddle attachment, cream with butter and sugar together until creamy. Mix in the egg, yolk, and vanilla on medium speed until thoroughly combined, scraping down the sides of the bowl as you go.

In a medium bowl, add the all-purpose flour, whole-wheat flour, cornstarch, baking soda, and salt. Slowly mix the dry ingredients into the wet ingredients. Mix until thoroughly combined. Add in the chocolate chips and walnuts and mix for a few seconds to combine.

Press the dough into the prepared cake pan, making sure that it’s evenly set. Bake until golden brown on top and slightly more browned along the edges, about 25 minutes.

Set on a wire rack to cool. Once cool enough to touch, remove from the cake pan and cool completely on the rack.

For the chocolate-coffee frosting

In a small bowl, mix the cream, espresso powder, vanilla, and salt together. In a medium bowl, sift the sugar and cocoa powder together.

In a stand mixer fitted with a paddle attachment, mix the butter until creamy. Add in the cocoa powder and cream mixtures a little at a time, alternating between the two, until thoroughly combined.

Frost the cookie cake as desired, and serve at room temperature.
