Cooling and Setting
Cool the Mixture: Leave it alone for a while until the mixture cools to 110°F. It is about half an hour.
Add Vanilla and Beat: After cooling, add vanilla extract to the mixture. The wooden spoon or electric mixer on slow speed would merge these results into a thickened concoction that loses some of its luster.
Pour into Baking Dish: Immediately pour this thickened fudge into the prepared baking dish, spreading evenly with an offset spatula.
Final Steps
Cool Completely: The fudge should then be left at room temperature till it is cool. This may take several hours or even overnight.
Cut into Pieces: When finally set, remove fudge from baking dish lifting it by parchment paper overhang. Cutting them into small squares using a sharp knife marks those little cubes of joy.
Serve and Enjoy: Fudge can be served immediately or stored in an airtight container for up to two weeks.
