Preheat oven to 350° and line a 9x9 baking pan with parchment paper. Spray with non-stick spray and set aside.
In a medium saucepan, combine coconut oil, cocoa powder, and unsweetened chocolate. Heat oven medium heat, whisking until mixture is smooth and no lumps remain.
Take off the heat and stir in the honey. This should cause the mixture to slightly thicken.
Add in the eggs and vanilla and mix well.
Add in the coconut flour, salt, and espresso powder. Mix until no dry pockets remain.
Pour into prepared pan and bake for 20-23 minutes.
Store in the fridge after the first day to keep fresh.
