Cook the batata: bake or steam until very soft. Cool completely.
Mash smooth: no lumps = truffle-quality “UX”.
Mix base: sweet potato + nut butter + sweetener + vanilla + cinnamon + salt (+ cocoa if using).
Add oat flour: mix in gradually until you get a dough that holds shape (soft but not sticky).
Too wet? add 1–2 tbsp more oat flour.
Too dry? add 1 tbsp milk/water.
Chill: 20–30 minutes (firms up, easier rolling).
Roll: form 1-inch balls.
Coat: roll in cocoa/coconut/nuts, or dip in melted dark chocolate.
Set: refrigerate 30 minutes if dipped
