Preheat the oven to 350 F. Line baking sheet with parchment paper.
Put chopped pecans and bake for 4- 5 minutes, until fragrant. Leave them aside, to cool.
In a medium dish, combine graham cracker crumbs and melted butter. Add light brown sugar, salt, caramel topping and cooled pecans and mix until well combined.
Put parchment paper in a baking sheet. Make balls - 1 tablespoon – 1 ball.
Place the balls on the parchment paper. Chill for about 30 min.
Melt chocolate and put it in a small deep bowl. Add oil and stir. Take the balls and coat them in the melted chocolate, using a fork.
Take the balls out with a fork and wait for a couple of seconds for the extra chocolate to drain.
You should be quick, if you want the truffles to keep their shape.
Take the balls off the fork using a smaller knife or a toothpick and place them back on the parchment paper.
Quickly sprinkle with pecans. Repeat with remaining truffles. Put them in the freezer for 10 - 15 min, until the chocolate sets.
Notes
They can be served immediately or kept in a well sealed container, in the fridge no longer than 7 days, or in the freezer up to 2 weeks
