Preheat oven to 350°F and grease a 7”x11” glass oven safe dish.
In a large bowl, or in the bowl of a stand mixer, combine granulated sugar, brown sugar, butter, eggs, vanilla, and salt. Whisk until batter is thick and well combined.
In the same bowl, sift in the almond flour and cocoa powder. This is a very important step as both almond flour and cocoa powder tends to clump up during storage. Gently stir batter until almond flour and cocoa powder are well combined and the batter is smooth.
In a microwave safe bowl, or in a double broiler, melt the chocolate chips. When the chocolate is completely melted, fold into batter until just combined.
Pour the batter into prepared dish and bake for 35 minutes.
Let cool completely before serving or adding the ganache.
