1/3 cup light brown sugar.
1/2 cup pecans or walnuts, chopped in very large pieces.
1 pack puff pastry, either pre rolled or rolled to about 1/4inch thickness.
1/4 c butter
2/3 cup light brown sugar, lightly packed
3 tsp. ground cinnamon
1 cup raisins (optional)
12 cup muffin tin.
Preheat the oven to 350 degrees. Make sure butter is soft then mix it with the third of sugar until it is a paste. Split the mixture between the bottoms of the 12 muffin pans. Distribute the nuts between the pans on top of the sugar and butter.
Roll out the pastry. Sprinkle the rest of the sugar over the pastry with the cinnamon. At this point you can add any combination of more nuts or raisons that you fancy. Roll the pastry back up with the sugar etc inside. Next slice the roll up into 12. Place each swirl with the swirl facing up into one of the pans on top of the nuts and butter.
Bake in the oven for about 30 mins. Once out of the oven leave to cool for about 5mins then up turn the whole pan. You should probably do this onto baking paper or tin foil. Some of the nuts will fall off at this point just put them back onto the top and once the sugar has cooled they will stick.
