In a large mixing bowl, beat butter until creamy (30 seconds). Add in brown sugar, egg, vanilla and almond extracts. Mix until combined. Add in flour and salt and mix until combined.
Spread mixture onto a 13x9 baking pan (ungreased). Bake for 15 minutes, or until golden, and edges start to brown.
Remove from oven and immediately sprinkle with chocolate chips. Let stand for a few minutes, until chocolate starts to melt, then spread evenly over cookie crust.
Sprinkle with toffee pieces and let cool before cutting.
