Preheat oven to 350 degrees F.
In a small saucepan over the stove on low heat, melt the coconut oil and 2/3 cup chocolate chips. Once liquid, remove immediately, then let cool for 15 minutes.
In a medium bowl, quickly whisk together the room temp eggs and coconut sugar for 30 seconds. Then whisk in the maple syrup, then pour in the cooled coconut oil / chocolate mixture, and whisk again.
Fold in the cacao powder and gently stir until just well combined. Sift in the almond flour, then making sure not to over-mix, stir together along with the baking soda, and majority of the remaining chocolate chips.
Add parchment paper to a 6x6 or 8x8 baking dish, then pour the mixture over the top, topping with final chocolate chips and a pinch of sea salt.
Bake for 22-25 minutes, then remove and let cool for 30 minutes before serving. Store any leftovers in the refrigerator, in an airtight container, for 1-2 days.
