INGREDIENTS:
For the Brownies:
1 stick (8 tablespoons) unsalted butter, at room temperature
1 cup granulated sugar
2 tablespoons cocoa, plus more for pan
2 eggs
1 teaspoon pure vanilla extract
3/4 cup flour
pinch of kosher salt
For the Ice Cream Sandwiches:
1 quart vanilla ice cream, slightly softened
2 pounds chocolate chips
1 teaspoon oil
DIRECTIONS:
Preheat the oven to 350 degrees. Butter a quarter sheet pan (a small jelly roll pan), or a 13x9inch pan. Place a sheet of parchment paper in the bottom, spread with butter, and dust with cocoa powder. Set aside.
In the bowl of an electric mixer fitted with the paddle attachment, cream together butter, sugar, and 2 tablespoons of cocoa powder. When the mixture is creamy, and all lumps are gone, add in eggs, one at a time, incorporating well after each addition. Add in vanilla.
