Old fashioned English butter toffee is rich and decadent made with only the finest plugra butter, almonds and chocolate.
Generously grease or line an 11x18 cookie sheet.
Chop nuts and spread 2 cups over the greased cookie sheet.
Cook butter, water, and sugar in large saucepan and over medium-high heat, stirring constantly until it reaches 300 degrees F or hard crack stage on thermometer.
Remove from heat and carefully stir in vanilla extract. It will spit a bit.
Once the chocolate chips have started to melt, spread with an offset spatula and sprinkle with remaining chopped nuts.
