Spread the pecan halves onto a baking sheet and toast in the oven about 8-10 minutes, or until fragrant and deep golden brown. Remove from oven and allow to cool.
In a medium saucepan over medium heat, combine the sugar, butter, and heavy cream. Stir constantly until mixture comes to a boil and sugar fully dissolves. Continue cooking about 4-5 minutes, or until caramel thickens. Remove from heat and stir in the vanilla extract and salt.
ON a parchment paper lined baking sheet, arrange small clusters of the toasted pecans (about 4-5 pecan halves per cluster).
Spoon a tablespoon of the caramel mixture evenly over each cluster, ensuring that are well coated. Let them cool and set for about 15 minutes.
Melt the chocolate chips in a microwave safe bowl, in 30 second increments until chocolate is smooth and melted.
Spoon the melted chocolate over each caramel pecan cluster covering them completely.
Allow the clusters to set at room temperature or refrigerate until the chocolate is firm.
Once chocolate has set, clusters are ready to enjoy!
