Step 1

Line a 13x9 pan with foil and then spray it with cooking spray or an oil mister. Set aside.

Step 2

In a 2qt heavy saucepan, combine brown sugar, sweetened condensed milk, butter, and corn syrup. Bring to a boil over medium heat.

Step 3

Cook & stir until the candy thermometer reads 248 degrees (firm ball stage). This should take about 25-30 minutes depending on the BTU's of your stove. Don't turn the heat higher to rush the process.

Step 4

Remove from heat and carefully stir in the vanilla extract.

Step 5

Carefully pour the caramel into the prepared pan. Move quickly as it will firm up fast.

Step 6

Let cool completely before pulling out of the pan by any overhanging foil. Cut into squares and wrap individually with parchment paper.
