Line a 9×9 square baking dish with parchment paper (or generously grease pan with butter).

Stir milk, brown sugar and butter together in a large saucepan over medium-high heat and bring to a boil.

Reduce heat to medium-low and cook for 5 minutes, stirring continuously. It will noticeably thicken.

Remove from heat and using a hand mixer, beat in salt, vanilla extract and the powdered sugar, 1 cup at a time, until combined and thickened.

Transfer mixture into prepared pan and cool until set.

Slice into squares to serve. (It is delicious if you stop here!) but…

For an extra layer of awesome, if desired, coat each square using melted chocolate or candy melts. Decorate with sprinkles. Enjoy!
