This is just a mashup of The Kitchn's How To Make a Single Rice Krispies Treat and smitten kitchen's salted brown butter crispy treats, written all together so I don't have to straddle two recipes: maximum efficiency so that I can make these in the shortest time possible, soon I will have this memorized. I have very limited patience for making non-essential food, and yet really like a) salted things, b) brown butter, and c) rice krispies treats. I have also historically had zero patience for making rice krispies treats because I couldn't even with wrestling that whole mass into a pan and getting it stuck to my handsghghghghgh. Making a single treat is so genius in this regard, though: I can show a single treat who's boss. Buttered hands and parchment paper help, too. And why even bother dirtying another pan, amirite.

Melt the butter in a small saucepan over medium-low heat. Stir constantly, until you start to see tiny brown grains forming in the melted butter. Keep stirring and cooking just a bit longer, but not too much longer or else you will burn the butter.

The Kitchn says this is a single treat, but it's a very large single treat and out of romantical niceness I cut it up to share with der schweetums. It cuts a bit better if it gets a chance to set up a bit, but—
