01 - Preheat oven to 350°F. Line a baking sheet with parchment paper.
02 - Melt 2 tablespoons butter in a small skillet over medium heat. Add diced apples, brown sugar, cinnamon, and salt. Cook, stirring, for 4-5 minutes until apples are tender and caramelized. Remove from heat and let cool slightly.
03 - Separate biscuit dough into individual pieces. Flatten each into a 4-inch circle.
04 - Place about 1 tablespoon of cooked apple filling and 1 caramel candy in the center of each dough circle. Gather edges around filling, pinching well to seal and form a ball. Place seam-side down on prepared baking sheet.
05 - Brush each pie bomb with melted butter. Combine sugar and cinnamon in a small bowl. Sprinkle generously over the pie bombs.
06 - Bake for 15-20 minutes, or until golden brown and puffed.
07 - Let cool slightly before serving, as caramel filling will be hot.
