Step 1

Line an 8x8 pan with foil so that it is sticking out over the edges.

Step 2

Seperately, and following the instructions on the bag, melt the chocolate in the microwave. A lot of the melting will occur from stirring the chocolate, stir very well after every 30 second interval, and be careful not to over heat the chocolate. It will likely be melted after less than a minute.

Step 3

Add half of the sweetened condensed milk to one bowl of melted chocolate and half to the other.

Step 4

Add the mint extract to the chocolate bowl, and add the green food coloring to the white chips. Stir until fully combined.

Step 5

Remove both pans from the heat and add a few spoonfuls at a time of each one to the pan. Continue adding randomly until both sauce pans are empty. Shake the 8x8 pan a little to make it even. Very gently run a butter knife a few times through to give it a swirled effect.

Step 6

Refrigerate overnight. Pull the foil (with the fudge) out of the pan and away from the fudge. Cut off the rough edges (just a very small amount to make a clean edge). Then cut the block of fudge into four large pieces. Cut each fourth into 9 pieces for a total of 36 pieces of fudge. Serve or store in an airtight container.
