Step 1
Start by mixing the sugar, flour, cocoa powder, cinnamon, and salt right in a microwave-safe mug. Then add the milk, melted butter, and vanilla, stirring everything together really well—make sure to scrape the bottom so no dry bits are left. Pop the mug in the microwave and cook on high for about a minute. The brownie will still be a little gooey in the center, which is perfect, but if it looks too wet for your liking, heat it for another 30 seconds. Just be careful not to go over two minutes total, or it’ll turn more cakey than fudgy. Let it cool for about five minutes before digging in—if you can resist that long!
