Toast the pecan halves in a dry skillet over medium heat for 3-4 minutes until fragrant. Set aside to cool.
In a small saucepan, melt the caramel candies over low heat, stirring until smooth and gooey. If using homemade caramel, prepare it as usual.
In a heatproof bowl, melt the semi-sweet chocolate chips and butter over a double boiler or microwave in 30-second intervals, stirring until fully melted and smooth.
On a parchment-lined baking sheet, place 3-4 pecan halves in a cluster shape. Spoon a small amount of melted caramel over the pecans, creating a little puddle of caramel.
Drizzle the melted chocolate over the caramel and pecans, covering the entire cluster.
Place the baking sheet in the refrigerator for 30 minutes, or until the chocolate has hardened and the caramel has set.
Once set, remove from the fridge, sprinkle with a pinch of sea salt (if desired), and enjoy!
