Ingredients:
- 1 cup (200g) unsalted butter, cubed
- 1 cup (200g) light brown sugar, packed
- 1/2 cup (160g) light corn syrup
- 1 can (14 oz / 397g) sweetened condensed milk
- 1 tsp (5ml) vanilla extract
- 1/2 tsp (3g) fine sea salt
Instructions:
- Line an 8x8 inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
- Combine the cubed butter, brown sugar, corn syrup, and sweetened condensed milk in a deep microwave-safe glass bowl.
- Microwave on HIGH for 3 minutes, then remove and stir vigorously with a spatula until smooth.
- Return to the microwave for another 2–3 minutes, stirring every 45 seconds, until the mixture bubbles and reaches a deep, golden mahogany color.
- Test the set by dropping a small spoonful of hot caramel into a glass of ice water; it should form a soft, pliable ball that holds its shape.
- Remove from microwave and immediately stir in the vanilla extract and salt.
- Pour the mixture into the prepared pan and smooth the top with a spatula.
- Allow the caramels to set at room temperature for 2 hours (or refrigerate for 1 hour for a faster set).
- Lift the parchment paper, slice the block into 64 small squares using a sharp knife or pizza cutter, and wrap individually in wax paper.
