Decent. Not as huge a fan of the texture of the super done parts along the edges of the brownie but it's still decent and something I will definitely be adding to my regular rotation especially with the fact that it takes like five minutes to do. Will be doing some experimenting with different ratios of whey/casein protein did full whey on my initial time doing it which usually doesn't give a great texture when it's cooked. And also I tend to struggle to get the perfect texture with mug brownies in general anyway so ¯_(ツ)_/¯
