Preheat your oven to 350°F (or 175°C). Ready an 8x8 inch baking pan by lining it with parchment paper or giving it a light greasing.
Take those lovely avocados, slice them up, discard the seed, and scoop the soft insides into a blender or food processor.
Add in the Kasein protein powder, cocoa powder, sugar, and vanilla extract. Give it a whirl until everything comes together into a creamy texture.
Crack in those eggs, one at a time, ensuring they’re thoroughly combined with the mix.
Toss in the baking soda and salt, ensuring they're mixed well.
If you’re feeling the chocolatey vibe, sprinkle in those dark chocolate chips.
Pour the concoction into your prepared baking pan.
Bake those Kasein Avocado Brownies for 25-30 minutes. You're looking for a toothpick to come out almost clean, hinting at their fudgy heart.
Let them cool down, show some patience, and then slice them up.
