2 cubes butter
2 2/3 C evaporated milk
4 C powdered sugar
2 t vanilla
Use a large pot. Melt butter on low heat. Add chocolate chips and stir until melted and smooth. Add evaporated milk and powdered sugar and turn heat to medium high. Bring to a boil. Reduce heat to about medium (just keep a low boil going) and set timer for 8 minutes. You don't want it boiling too hard. Stir constantly. Remove from heat and add vanilla. It will thicken up a bit. It makes 5 - 6 cups.
*I almost always halve this for our family and boiling for 6 minutes is about right for halving it. I've found that half a bag of chocolate chips is one heaping 3/4 C not just 1 C even.
*This is my mother-in-law's infamous recipe. She says she has tried other chocolate chips and it's the best with Nestle semi-sweet.
