01 - Place the 7 oz chopped dark chocolate in a heatproof bowl and set aside while heating the cream.
02 - In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer. Do not let it come to a full boil.
03 - Pour the hot cream over the chopped chocolate. Let stand undisturbed for 2 minutes, then gently stir until completely smooth and fully melted.
04 - Stir in the softened butter, alcohol-free Irish cream syrup, vanilla extract, and salt until fully incorporated and glossy.
05 - Cover the bowl and refrigerate the mixture for 1 to 2 hours until firm enough to scoop and hold its shape.
06 - Line a baking sheet with parchment paper. Using a melon baller or teaspoon, scoop small portions of ganache and roll into balls between lightly cocoa-dusted palms. Place on the prepared sheet.
07 - Transfer the baking sheet to the freezer for 20 minutes to firm the truffles before coating.
08 - Melt the 7 oz coating chocolate with coconut oil if using in a heatproof bowl over simmering water or in 20-second microwave bursts, stirring until completely smooth.
09 - Using a fork or dipping tool, dip each chilled truffle into the melted chocolate, allowing excess to drip off. Return to the parchment-lined sheet.
10 - While the chocolate coating is still wet, sprinkle with cocoa powder, chopped toasted hazelnuts, or chocolate sprinkles as desired.
11 - Let truffles set at room temperature until firm, or refrigerate for faster setting. Store in an airtight container.
