01 - In a heatproof bowl, mix the chopped semi-sweet chocolate, instant espresso powder, and salt.
02 - Warm the heavy cream and butter in a small saucepan over medium heat until just simmering.
03 - Pour the hot cream mixture over the chocolate blend. Let rest for 2 minutes, then stir until smooth.
04 - Mix in the peppermint and vanilla extracts thoroughly.
05 - Cover and refrigerate for 1 to 2 hours until the ganache firms enough to scoop.
06 - Line a baking sheet with parchment paper. Using heaping teaspoons, scoop ganache and roll into balls. Place on the sheet and freeze for 15 minutes to set.
07 - In a microwave-safe bowl, melt the coating chocolate with coconut oil in 30-second intervals, stirring until smooth.
08 - Use a fork to dip each truffle into the melted chocolate, allowing excess to drip off before placing them back on the baking sheet.
09 - Sprinkle crushed peppermint candies onto each truffle before the coating solidifies.
10 - Let the coated truffles set at room temperature or refrigerate until firm.
