Preheat your oven to 350°F (175°C) to ensure even baking and a perfect fudgy texture.
Line your 9x9-inch baking pan with parchment paper, allowing some overhang for easy removal of the brownies.
In a medium mixing bowl, whisk together the almond flour, cocoa powder, baking soda, and salt until well combined.
In another bowl, mix the coconut sugar, melted coconut oil, egg, egg yolk, and vanilla extract until smooth and well blended.
Pour the wet ingredients into the dry ingredients and mix until just combined, being careful not to overmix.
Fold in the dairy-free mini chocolate chips evenly throughout the batter.
Pour the batter into the prepared baking pan and spread it out evenly. Bake for 20-25 minutes, or until a toothpick inserted comes out with a few moist crumbs.
Allow the brownies to cool in the pan for 10 minutes, then lift out using the parchment paper and cool completely on a wire rack before cutting into squares.
