Prep the chocolate: Chop the keto chocolate into small, even pieces and place in a heatproof bowl. The smaller the pieces, the smoother your ganache.
Heat the cream: In a small saucepan, warm the heavy cream over medium-low heat until it gently simmers around the edges.
Do not let it boil.
Combine and rest: Pour the hot cream over the chopped chocolate. Let it sit untouched for 2 minutes to soften the chocolate.
Stir to a smooth ganache: Add the butter, powdered sweetener, orange zest, orange extract, vanilla, and a pinch of salt. Stir slowly from the center outward until glossy and fully combined.
Taste and adjust sweetness or orange extract as needed.
Chill: Cover the bowl and refrigerate for 1.5–2 hours, or until the mixture is firm enough to scoop but not rock hard.
Portion: Line a baking sheet with parchment. Using a small cookie scoop or teaspoon, portion the ganache into 1-inch balls and place on the sheet.
Shape: With clean, cool hands, roll each portion into a smooth ball. If it gets too soft, chill for 10 minutes and continue.
Coat: Roll truffles in your chosen coating—cocoa powder for classic, nuts for crunch, or dip in melted keto chocolate for a shell.
If dipping, let them set on parchment until firm.
Set and serve: Chill for 15–20 minutes to firm up coatings. Enjoy slightly cool or at room temperature.
