HOW TO MAKE MILLIONAIRES SHORTBREAD RECIPE:

  1. To make the filling place the butter, brown sugar, condensed milk, and corn syrup into a medium-sized sauce pot. Place over medium-low heat, stirring constantly.
  2. Bring to a simmer and turn the heat to low. Gently simmer for 5 minutes, stirring constantly so nothing burns on the bottom. You really have to be careful and make sure it doesn’t boil because a bubble may pop and burn you. If it looks like it is starting to simmer more rapidly, take off the heat for a few seconds while continuing to stir, then place it back on the heat.
  3. After 5 minutes, take it off the heat and continue to stir for about 4 minutes to cool it down slightly. Pour over the crust evenly. Place in the freezer for 2 hours.
  4. Add the chopped chocolate and butter into a microwave-safe bowl. Microwave in 15-second intervals stirring in between until smooth. Spread the chocolate on top of the filling. Place in the fridge for 2 hours to set.
