03 - Add milk and vanilla extract to the creamed mixture and blend until combined.
04 - Stir in the cooled heat-treated flour and salt until thoroughly mixed.
05 - Gently fold mini chocolate chips into the dough.
06 - Scoop tablespoon-sized portions and roll into balls. Arrange on a parchment-lined baking sheet.
07 - Freeze dough balls for 20 to 30 minutes until firm.
08 - Melt chocolate and coconut oil (if using) in a microwave or double boiler until smooth.
09 - Using a fork or dipping tool, coat each chilled dough ball with melted chocolate, allowing excess to drip off.
10 - Place coated truffles on the parchment-lined sheet. Optionally drizzle with extra chocolate or sprinkle with mini chips.
11 - Refrigerate until the chocolate is firm, approximately 15 minutes. Serve chilled or at room temperature.
