Combine panko crust ingredients and pour all but 1/2 cup into an 8-inch pie plate. Spread crumbs up the sides of the pie plate. Gently press crumbs on the bottom and sides. Set aside.
In a small pot over low heat, melt butter. Stir in coconut sugar and continue cooking on low until sugar is dissolved. Remove from heat, add vanilla and eggs and whisk to combine.
In a separate bowl, whisk together cocoa, flour, and salt. Add dry ingredients to butter mixture and stir just until combined. Add chocolate chips and gently toss to combine.
Pour brownie mixture in the prepared pie plate. Bake for 25 minutes. Cool completely on a wire rack before slicing.
