Mix the Base: In a bowl, combine peanut butter, almond flour, sweetener, vanilla extract, and a pinch of salt.Mix it until everything blends into a thick, dough-like mixture.
Form the Balls: Scoop out small amounts of the mixture and roll into 1-inch balls using your hands. Place them on a parchment-lined plate or tray.
Optional Chocolate Coating: If using chocolate, melt sugar-free chocolate chips with coconut oil in the microwave or over a double boiler. Dip or drizzle the balls with chocolate.
Chill to Set: Refrigerate the peanut butter balls for 15 minutes (or freeze for 10) to firm them up before serving.
