Caramel Pecan Clusters

Line a baking sheet with parchment paper and set aside.
To a saucepan over medium-high heat, add the brown sugar, light corn syrup, and salt. Stir to dissolve sugar in the corn syrup. Keep slowly stirring as mixture heats up.
Once mixture starts to gently bubble, drizzle in the heavy cream very slowly while continuing to stir. Mixture must continue to bubble, so add cream very slowly.
Add butter, continuing to stir. Keep stirring until a candy thermometer reads 245°F. This should take about 15 minutes.
Remove from heat and quickly stir in vanilla and pecans.
Scoop mixture out with a small cookie scoop onto prepared baking sheet.
Gently shape scoops with a fork to make candy into taller mounds, if desired. Let candy sit until set, and enjoy!
