Method
- Preheat the oven to 375° and lightly grease a 9-inch springform pan.
- In a medium bowl, cream the butter, brown sugar, and granulated sugar together. Beat very well, about 60 seconds.
- Add the egg, egg yolk, and vanilla to the bowl, and beat until combined.
- In a small bowl, whisk together remaining ingredients (except chocolate chips) and add it in 2 batches to the creamed butter, beating just to combine.
- Stir in the chocolate chips.
- Press the dough into the pan and press it evenly flat. Scatter extra chocolate chips on top.
- Bake for 23-27 minutes, until the middle is slightly underdone (it will set up as it cools).
- Optional: make a half-batch of chocolate buttercream, and decorate the cookie cake with it and sprinkles.
Notes
For an extra decadent touch, serve with a scoop of vanilla ice cream or drizzle with caramel sauce.
