Preheat oven to 400 degrees Fahrenheit 

In a bowl mix, the butter and the brown sugar set aside

On a floured surface, place the thawed Puff Pastry and spread using a rolling pin

Spread the pumpkin puree all over the puff pastry leaving a 1-inch border on all sides. Sprinkle in 1 tablespoon of Pumpkin spice seasoning

Using a serrated knife cut carefully into 6 equal pieces

Grab a muffin tin and place it on a cookie sheet (sticky buns will boil over inside the oven)

Inside each muffin crevice, add a little of the butter-sugar mixture and sprinkle with the walnuts

Add the rolls cut side up inside each crevice and press them lightly

Repeat with second Puff Pastry sheet

Bake for 30 minutes or until the tops are browned

When they are ready, carefully invert them on a cookie sheet lined with parchment paper. Beware, contents will be hot

Spoon the walnuts on top of each bun
