Preheat your oven to 350°F (175°C) and prepare an 8×8-inch baking pan.

In a large bowl, whisk together the almond flour, cocoa powder, baking powder, and salt until combined.

In a separate bowl, whisk the eggs until pale, then add melted butter and vanilla extract. Stir in the granulated sugar until smooth.

Pour the wet mixture into the dry ingredients and fold gently until just combined.

Fold in the chopped chocolate or chips until evenly distributed.

Pour the batter into the prepared pan and bake for 20-25 minutes.

Let the brownies cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
