Ingredients
  

Cookie Cake

  • 150 g granulated sugar
  • 1 large egg
  • 1 egg yolk
  • 2 tsp vanilla extract
  • 150 g gluten-free 1:1 baking flour
  • 56 g blanched almond flour or ⅓ cup more gluten-free flour for nut-free version
  • 0.5 tsp baking powder
  • 0.5 tsp salt
  • 170 g semi-sweet chocolate chips use mix of regular and mini, crush half if desired

Chocolate Frosting

  • 113 g butter softened
  • 180 g powdered sugar
  • 25 g cocoa powder
  • 2 tsp milk or more as needed
  • 1 tsp vanilla extract
  • 1 pinch salt

Instructions
 

  • Preheat oven to 350°F (175°C). Grease a 9-inch round pan and line the bottom with parchment paper.
  • Brown your butter: melt in a pan over medium heat, stir until golden and nutty-smelling. Let cool 10 minutes.
  • In a large bowl, mix brown butter, brown sugar, and granulated sugar until smooth.
  • Stir in the egg, egg yolk, and vanilla until glossy.
  • Whisk together gluten-free flour, almond flour, baking powder, and salt. Add to wet ingredients and stir just until combined.
  • Fold in chocolate chips (crush half for better spread).
  • Spread dough evenly into the prepared pan. Press flat.
  • Bake for 30–35 minutes, until edges are golden and center is set. Toothpick should come out with a few moist crumbs.
  • Cool completely in the pan before frosting or slicing.
  • For frosting, beat butter until smooth. Add powdered sugar, cocoa, vanilla, salt, and milk. Beat until fluffy, adding more milk if needed.
  • Frost cooled cookie cake as desired. Pipe edges or drizzle with melted chocolate. Add sprinkles for decoration.

Notes

Letting the cake cool fully ensures clean slices. For nut-free, swap almond flour with more gluten-free flour. Store frosted cake in the fridge and allow to come to room temp before serving.
