Preheat your oven to 350°F (175°C). Grease an 8x8-inch baking pan with a little coconut oil or line with parchment paper.
Prepare the wet ingredients: In a large mixing bowl, combine the mashed avocado, melted coconut oil, molasses, maple syrup, eggs, and vanilla extract. Whisk until smooth and creamy.
Add the dry ingredients: To the same bowl, sift in the almond flour, cocoa powder, ground ginger, cinnamon, nutmeg, sea salt, and baking soda. Mix until just combined, making sure there are no dry spots. The batter should be thick and fudgy.
Pour and smooth the batter into your prepared baking pan, spreading it evenly with a spatula.
Add the chocolate chips on top if desired, gently pressing them into the batter.
Bake for 25–30 minutes, or until a toothpick inserted in the center comes out mostly clean. The brownies will continue to set as they cool.
Cool completely in the pan before cutting into squares.
