Preheat the oven to 350°F and line an 8x8-inch pan with parchment paper, leaving overhang on two sides.
Melt the coconut oil and chopped dairy free dark chocolate together in 30-second bursts in the microwave, stirring between each, until smooth. Let cool for 5 minutes.
Whisk both sugars into the melted chocolate. Add the eggs one at a time, whisking vigorously for 30 seconds after each. This step creates the shiny, crackly top.Whisk in the vanilla.
Fold in the flour, cocoa powder, and salt just until combined, then fold in the dairy free chocolate chips.
Spread the batter evenly into the pan and bake for 28 to 32 minutes, until a toothpick comes out with moist crumbs but no wet batter.
Cool completely in the pan before lifting out and portioning into squares. For extra clean edges, chill for 30 minutes first.
