In a microwave-safe bowl, combine 1 cup of semi-sweet chocolate chips. Heat in the microwave at 20-second intervals, stirring until melted and smooth.

Once your chocolate is melted, stir in the 14 oz can of sweetened condensed milk until fully incorporated.

Process ¼ cup of walnut pieces in a food processor until they resemble small crumbs.

Use a 1-ounce cookie scoop or your hands to portion out the chocolate dough and roll each into a smooth ball.

Gently roll each chocolate ball in the processed walnut crumbs until completely coated.

Place the truffles on a baking sheet lined with parchment paper and refrigerate for an additional 15-20 minutes to set.
