I received this recipe back in the late 1970's from a gal who worked in the laboratory of our hospital.
It became a favorite in our family, and we still make it for the holidays.
These were recently made by my oldest daughter. When I looked for my recipe, I could not find it.

My youngest daughter was kind enough to send the recipe along with her own side notes which I found to be amusing.

1 lb. DATES, chopped
1/2 c. WALNUTS, chopped
2 c. CONFECTIONER'S SUGAR
6 Tbsp. BUTTER, melted
12 ounce jar CHUNKY PEANUT BUTTER
7 oz. CHOCOLATE CHIPS
A little less than 1/2 bar of PARAFFIN (yes... it is edible and helps to set the chocolate and make it glossy)

Mix together the dates, walnuts, confectioner's sugar, butter and peanut butter.
Shape into balls to make stuffing your face easier.

Melt chocolate and yummy paraffin in a double boiler.

Dip heart attack balls into chocolate.

Place in pretty little paper cups that make them look innocent and dainty and not at all like something you shouldn't be eating.

(I admit... I like them too, but my thighs do not!)
