Preheat oven to 350 ° and line a 8 “-x-8” baking pan with parchment paper and grease with cooking spray. In a large bowl, whisk together cocoa powder, almond flour, baking soda, and salt.
In a medium bowl, whisk together almond butter, coconut sugar, honey, oil, eggs, and vanilla until smooth. Add dry ingredients and stir until just combined.
Pour into prepared pan and bake until a toothpick inserted in the middle comes out clean, 22 minutes.
Sprinkle with sea salt then let cool slightly before serving.
