1 ⅓ cup of brown sugar
½ cup granulated sugar
3 large eggs room temperature
1 tbsp vanilla
1 tsp baking soda
1 tsp cornstarch
½ tsp salt
3 cups all purpose flour
2 cups of chocolate chips
Buttercream icing
100g room temperature unsalted butter
200g icing sugar
1 tsp vanilla extract
Optional
Food coloring and sprinkles
Heat the oven at 350°F. Grease a 13x18 sheet pan or a large pizza tray. I used a silicone mat to avoid this step.
I used a mixer but it could be done by hand.
Cream the butter and sugars together (if doing it by hand, melt the butter), incorporate one egg at the time, add vanilla, continue to mix. Add baking soda, cornstarch and salt. Add flour ½ cup at the time, do not overmix. Using a spatula add 1 ½ cups of chocolate chips into the cookie dough.
Evenly distributed the mix into the prepared sheet pan, is going to be a thin layer. Sprinkle the reserved ½ cup of chocolate chips to the top and bake for about 14 minutes or until the edges are golden brown. Let it cool down completely.
For the icing, add all ingredients to the mixing bowl using the paddle attachment mix until the icing is creamy and fluffy. Separate to add colors. Integrate color with a spatula, decorate cookie cake when is at room temperature. Decorate with sprinkles.
