Preheat the oven to 350°F (180°C).
Grease an 8-inch (20-cm) cake pan with cooking spray or coconut oil.
In a mixing bowl, combine the almond flour, cocoa powder, baking powder, baking soda, and salt.
In a separate mixing bowl, whisk together the eggs, sugar, and vanilla extract until smooth.
Add the melted coconut oil and milk to the egg mixture, and whisk until well combined.
Add the dry ingredients to the wet ingredients, and mix until a smooth batter forms.
Fold in the dark chocolate chips.
Pour the batter into the prepared cake pan.
Bake for 30-35 minutes, or until a toothpick inserted into the center of the cake comes out clean.
Remove the cake from the oven and let it cool completely in the pan.
Once cooled, remove the cake from the pan and serve with your favorite toppings.
