8x11 inch baking dish (or a 10x10 inch baking dish)
Ingredients
¾cupunsalted butter,melted
¾cupgranulated sugar
¼cuplight brown sugar,lightly packed
2tspvanilla extract
2large eggs
2cupsall-purpose flour,fluffed, spooned and leveled
6tbspunsweetened Dutch processed cocoa powder
¾tspbaking soda
¾tspcoarse Kosher salt(if using table salt, use half the amount)
¾cupsemi sweet chocolate chips,divided
1cupvery hot water
Instructions
Preheat the oven to 350 F, and position a rack in the center of the oven. Lightly spray an 8x11 or 10x10 inch baking dish with non-stick baking spray.
In a bowl, whisk together the melted butter, granulated sugar, brown sugar, vanilla and eggs, until smooth.
In a separate bowl, combine the flour, cocoa powder, baking soda and salt. Add the flour mixture and half the chocolate chips to the wet ingredients, and stir everything together with a spatula. The batter will be thick, like cookie dough.
Spread the batter evenly into the prepared pan, then pour the hot water on top of the batter.
Bake the cake for about 25 minutes (for a gooeyer texture) or 30 minutes (for a more set texture).
Sprinkle the remaining chocolate chips on top of the hot cake. Let the cake cool for 15-30 minutes, then serve warm, topped with ice cream. When hot, the edges of the cake will be more set, while the center is very soft and gooey. Once the cake cools completely, it will set up more like a fudge brownie, and can be cut into squares.
Notes
Store the leftover cake in an airtight container at room temperature for up to 3-5 days.Reheat leftover pieces in the microwave for 20-30 seconds at 50% power.
