Ingredients
Method
Make the Cookies
- Preheat oven to 350°F (175°C) and prepare two 8-inch round cake pans with parchment paper and butter or nonstick spray.
- Melt half the butter in a microwave or pot, then whisk in the brown sugar, milk, and salt until smooth. Let cool.
- Add egg and vanilla to the mixture and whisk until combined.
- Sprinkle with baking powder and mix well.
- Stir in flour and 1/2 cup of chocolate chips until flour disappears.
- Pour half the batter into each pan and sprinkle with 2 tablespoons of chocolate chips.
- Bake for about 15 minutes until golden and set but soft in the center.
- Cool on a rack for 5 minutes, then remove from pans and freeze for 10 minutes.
Assemble the Cake
- Line one cake pan with plastic wrap extending up the sides.
- Place the first cookie round top side down in the pan and scoop vanilla ice cream evenly on top.
- Place the second cookie top side up on the ice cream and press down lightly.
- Cover with the plastic wrap and chill for 3 to 6 hours, ideally overnight.
Finish and Serve
- Remove the cake from the freezer and run a knife around the edges.
- Lift the cake out using the plastic wrap and pat the remaining chocolate chips onto the sides.
- Cut into 8 to 12 wedges and serve immediately.
Notes
The cake can be kept frozen for weeks. For individual ice cream sandwiches, pour the batter into a 9×13-inch pan after baking, cut, and fill with ice cream.
