Dark Chocolate Avocado Brownies with Peanut Butter Greek Yogurt Frosting

Hear me out. Don't close your browser. I promise these are worth your time. I mean I hope you can trust my brownie judgement, I am a brownie connoisseur. Should I remind you of the PB&J Pretzel Swirl Brownies? Or those Mound Bar Brownies I made? And remember how good Peppermint Hot Chocolate Brownies were? And how mouth-watering-ly good those Marzipan Brownies were?

Do you really think I would lead you astray? I am insulted. Unless you're still reading and are ready to believe what I tell you, no matter how strange. In which case, I am flattered.
