2/3 cup mashed potatoes (without butter, salt, or anything else added)
2 pounds powdered sugar
1 large package shredded coconut
1 teaspoon vanilla
Butter a 9 x 9 inch baking pan, and spread mixture in it evenly. Then melt in a quart-sized microwave-proof bowl (or on the stove in a double boiler) 1 large package of semisweet chocolate chips, with 1 stick of butter or margarine. Spread evenly over the potato mixture, and then chill for about 15 minutes. “Mark” the chocolate (which hardens quickly) with a knife so you can cut it more easily later. Chill until firm, several hours at least, before cutting into small pieces (these are very rich!). Keep refrigerated until ready to use, and refrigerate the uneaten pieces if you have any…but you won’t.
