Preheat your oven to 350°F (175°C) and line an 8x8-inch baking pan with parchment paper.

In a mixing bowl, mash the ripe avocados until smooth.

Add granulated sugar, eggs, and vanilla extract to the mashed avocados and whisk until combined.

Sift in cocoa powder, flour, and baking powder; gently fold until just mixed.

Pour the batter into the prepared pan and spread evenly. Bake for 25-30 minutes or until a toothpick comes out with moist crumbs.

Allow cooling for at least 10 minutes before slicing into squares.
