Preheat the oven to 375 degrees Fahrenheit. Line a rimmed baking sheet with parchment and lightly mist with nonstick spray.

Dice the apples into small even cubes. Toss with lemon juice, brown sugar, granulated sugar (if using), cinnamon, and a pinch of salt. Set aside.

Open the cinnamon roll can and reserve the icing packet. Cut each roll into four pieces.

Toss the dough pieces with melted butter. Sprinkle on a little cinnamon sugar from the apple mixture for extra flavor.

Spread dough pieces across the baking sheet in a single layer with small gaps. Spoon the spiced apples over and around the dough pieces so every bite has fruit.

Bake on the middle rack for 13 to 16 minutes until dough is puffed and golden and apples are tender. Rotate the pan once for even coloring.

Check doneness by pressing a center piece lightly; it should spring back and look set. If dough is pale, bake for an additional two minutes.

Mix the reserved icing with a splash of vanilla extract; if too thick, loosen with a teaspoon of warm milk or water.

Cool the baked pan for five minutes. Drizzle the icing in zigzags over the bites. Add chopped pecans if desired.

Serve warm by sliding a spatula under clusters and transferring to a platter. Add small skewers for easy grabbing at parties.
