1 cup Brown Sugar (Use coconut sugar for a deeper taste.)
1 can Sweetened Condensed Milk (No direct substitutes recommended.)
1/4 cup Corn Syrup (Light or dark corn syrup works well.)
1/2 cup Butter (Unsalted preferred for flavor control.)
1/4 teaspoon Salt (Use kosher or sea salt.)
1/2 cup Fireball Whiskey (Can be substituted with regular whiskey and a pinch of cinnamon.)
1 teaspoon Vanilla (Opt for vanilla bean for a more robust taste.)
Instructions
Prepare by lining a 9×9 or 8×8 baking pan with parchment paper.
In a heavy-bottomed saucepan, combine unsalted butter, brown sugar, corn syrup, sweetened condensed milk, Fireball whiskey, and salt, stirring until well incorporated.
Cook over medium heat without stirring until the mixture reaches a rolling boil, monitoring closely for about 10-15 minutes.
Remove from heat and stir in vanilla extract until smooth.
Pour the mixture into the prepared baking pan and let cool undisturbed at room temperature for 2 to 4 hours.
Cut the cooled caramels into squares and wrap each piece in wax paper.
