How to Make It
Preheat the oven to 350°. Spread the walnuts on a baking sheet and toast in the oven for 10 minutes, until they are fragrant and beginning to brown. Remove from the oven; leave the oven on.
In a medium bowl, use an electric mixer to cream together the butter and sugar. Add the eggs, vanilla and sea salt and beat to combine. Add the cocoa powder and coconut flour and beat until no lumps remain. Stir in the toasted walnuts and chocolate chips.
Line a baking sheet with parchment paper. Drop the batter by heaping tablespoons onto the prepared baking sheet.
Bake in the preheated oven for 15 to 18 minutes, until the bottoms are lightly browned. Set aside to cool completely before serving.
