Step 1

Preheat the oven to 400 degrees F. Place a 12-cup standard muffin tin on a sheet pan lined with parchment paper.

Step 2

In the bowl of an electric mixer fitted with the paddle attachment, combine the 12 tablespoons butter and 1/3 cup brown sugar. Place 1 rounded tablespoon of the mixture in each of the 12 muffin cups. Distribute the pecans evenly among the 12 muffin cups on top of the butter and sugar mixture.

Step 3

Lightly flour a wooden board or stone surface. Unfold 1 sheet of puff pastry with the folds going left to right. Brush the whole sheet with the melted butter. Leaving a 1-inch border on the puff pastry, sprinkle each sheet with 1/3 cup of the brown sugar, 1 1/2 teaspoons of the cinnamon, and 1/2 cup of the raisins. Starting with the end nearest you, roll the pastry up snugly like a jelly roll around the filling, finishing the roll with the seam side down. Trim the ends of the roll about 1/2-inch and discard. Slice the roll in 6 equal pieces, each about 1 1/2 inches wide. Place each piece, spiral side up, in 6 of the muffin cups. Repeat with the second sheet of puff pastry to make 12 sticky buns.

Step 4

Bake for 30 minutes, until the sticky buns are golden to dark brown on top and firm to the touch. Be careful - they're hot! Allow to cool for 5 minutes only, invert the buns onto the parchment paper (ease the filling and pecans out onto the buns with a spoon) and cool completely.
