- Mash the avocado first, then add all of the ingredients into one bowl. Mix until it is well combined.
- Line your cake pan with parchment paper, then pour the brownie batter into it. Bake at 350°F for about 45-50 minutes. You can stick a toothpick into the center of the brownies, and if it comes out clean, they are done baking.
- Allow them to cool before removing from the pan and serving.
For a richer coffee flavor, you can use brewed coffee (cooled down) instead of water, and increase the amount of espresso powder.
