In a stand mixer (or hand mixer), cream together butter and both sugars on MED-HIGH heat until light and fluffy.

Beat in sweetened condensed milk and vanilla extract.

Beat in salt and flour. Stir in mini chocolate chips.

Use a small cookie scoop or tablespoon measuring spoon to scoop out small portions of the dough. Using your hands, mold into ball shapes.

Place on a waxed paper lined baking sheet and freeze until solid.

Bring 1 inch of water to a simmer in a small sauce pan. Place dark chocolate wafers in a small glass bowl and place bowl over the top of the saucepan, making a double boiler. Do not allow the bottom of the bowl to touch the water!

Melt the chocolate, stirring often, until smooth and creamy.

Remove balls from the freezer. Insert a toothpick into a ball and dip into the melted chocolate.

Place ball back onto wax paper lined baking sheet to allow the chocolate to harden.

Repeat with remaining balls.

Once chocolate has hardened, remove toothpicks and use a small butter knife or the back of a spoon to smear melted chocolate over the toothpick hole.

Melt milk chocolate chips and drizzle over the top of the balls.

Place in refrigerator to harden and set.

Keep refrigerated until ready to eat.
