Combine caramels [11 ounces], heavy cream [3 tablespoons], and butter [1 tablespoon] in a small saucepan and melt over low heat, stirring occasionally.
Once the caramels have melted, add the peanuts and stir to combine.
Add the vanilla [1 teaspoon].
Remove from the heat and allow to cool for 15 to 30 minutes.
Prepare a baking sheet by covering with wax paper, nonstick foil or parchment paper.
Scoop the mixture out into 1 to 1 1/2 teaspoon mounds 2 inches apart. They will spread out as they cool.
Place in a refrigerator or freezer until set, 10 to 20 minutes.
Melt the almond bark according to the package directions.
Cover the caramel clusters completely with coating, allow the excess to drip off, set back onto the prepared surface and allow to cool until the coating is completely set.
