Brown the butter ahead and let it cool to prevent melting the peanut butter and thinning the dough; it should be fluid but not hot. Sourdough discard adds tenderness and a subtle tang—if your discard is very wet, hold back 1 to 2 tablespoons until you gauge dough consistency; it should be soft but scoopable. For gluten development control, avoid overmixing after flour is added. If using natural peanut butter, stir thoroughly and add 1 to 2 tablespoons extra flour if the dough feels greasy. Bake to just-set edges for fudgy centers; overbaking leads to dryness. The sugar roll adds a crackly crust, while a pinch of flaky salt on top after baking enhances flavor. Dough balls freeze well; bake from frozen at 350°F for 12–14 minutes.
