Preheat the oven to 350°F. Take the frozen dinner rolls out to thaw.
In a medium-sized bowl add 1 cup of the pecans, egg, granulated sugar, corn syrup, and 2 tablespoons of the butter, stir to combine.
Grease an 8x8 baking dish with cooking spray and set aside.
Once the dough is thawed, lightly dust a clean work surface and roll out or use your hands to form the dough balls into a flat circle about 4 inches wide.
Add about 1 tablespoon of the pecan filling. Gather the dough around the filling and pinch the seams together. Gently roll into a ball and place it into the baking dish seam side down.
Repeat with the remaining dough balls and filling. Brush the tops with the remaining 2 tablespoons melted butter. Sprinkle the brown sugar on top. Bake for 30-35 minutes until golden brown.
While the bombs are baking, add the remaining ½ cup of the pecans and the caramel sauce to a small bowl, stir to combine. Let the bombs cool slightly and add the caramel topping to serve.
