homemade twix bars

These were a very big hit today. My sisters agreed that these are better than the real thing and one said she wanted to hide a secret stash. I have to admit they're pretty good.

homemade twix bars (blog: Cucina di Harwood)
1 1/4 cup flour
1/4 cup sugar
1/2 cup butter, room temperature

caramel
1/2 cup butter
1/2 cup brown sugar
2 tablespoons corn syrup
1/2 cup sweetened condensed milk

chocolate
1 1/2 cups chocolate chips
1 teaspoon shortening

Crumble crust ingredients together and be sure it is mixed very well. Pack into a 9x9 inch pan that has been sprayed, lined with foil and sprayed again. Bake at 350 degrees for 15-20 minutes. Put the butter for the caramel filling in a heavy saucepan and melt. Combine remaining ingredients. Bring to a boil over medium heat. As soon as it starts to boil start a timer and boil for 5 minutes, stirring constantly. Remove from heat and stir with a spoon slowly until it shows signs of thickening, a few minutes. Pour over crust and let cool a little. For the chocolate layer, melt the chocolate chips and shortening in the microwave. Pour over caramel layer and spread carefully. Cut into bars. Enjoy!
