Begin by heating the all-purpose flour in the microwave for about 1 minute to eliminate any potential bacteria. Allow to cool slightly.
In a medium bowl, beat the softened butter, brown sugar, and granulated sugar together until light and fluffy, about 2-3 minutes.
Mix in the milk and vanilla extract until combined.
Gradually add the cooled flour to the butter mixture, mixing until just incorporated.
Gently fold in the mini chocolate chips.
Using your hands, form the dough into small balls, about 1 inch in diameter, and place them on a parchment-lined baking sheet.
Once all the cookie dough balls are formed, refrigerate them for at least 30 minutes to firm up.
While the dough balls are chilling, melt the chopped semisweet chocolate in a microwave-safe bowl in 20-second intervals, stirring in between, until smooth.
Remove the chilled cookie dough balls from the refrigerator and dip each one into the melted chocolate, ensuring they are fully coated.
Return the dipped truffles to the baking sheet. Before the chocolate sets, sprinkle lightly with sea salt for a delightful contrast.
Allow the chocolate to harden at room temperature, or refrigerate for quicker setting.
Notes
Serve the truffles in decorative mini cupcake liners on a platter. Optionally, drizzle with melted chocolate for an elegant touch.
