Preheat the oven to 350°F and spray the wells of a muffin tin with nonstick spray.
In a medium bowl, mix together the pumpkin puree, ½ cup brown sugar, melted butter, pumpkin spice, ground cinnamon, and allspice.
½ cup pumpkin puree, ½ cup light brown sugar, ⅓ cup salted butter, 1 tablespoon pumpkin spice, 2 teaspoons ground cinnamon, 1 teaspoon ground allspice
Dust a clean countertop with the flour and roll out one can of crescent roll dough, pressing all the seams together. Roll with a rolling pin until thin, but not too hard. Make sure the dough isn't sticking to the countertop.
¼ cup all-purpose flour, 3 (8oz.) cans Hawaiian Crescent Rolls
Spread a third of the pumpkin puree mix over crescent roll dough and roll up from the long side to create a log.
Cut the log directly in half then cut the halves lengthwise, you will be able to see all the layers.
Roll up the sliced dough just like you would a cinnamon roll and place the dough in the prepared muffin pan.
Repeat with the other two cans of dough and the remaining pumpkin puree. Each can of dough will make 4 muffins.
Sprinkle the remaining ½ cup of light brown sugar and the chopped pecans on top of the muffins.
½ cup light brown sugar, ½ cup pecan pieces
Bake for 15 to 18 minutes or until done. Remove from oven and allow to cool.
Prepare the optional glaze by whisking together the powdered sugar and milk in a small bowl.
½ cup powdered sugar, 2 tablespoons whole milk
Drizzle glaze over cruffins and serve.
