Remove from refrigerator and unwrap 1 dough disk and roll into a 10" circle (about 1/4" thick) on a lightly floured surface (silpats make great surfaces, too). Spread about 3 1/2 tablespoons butter mixture in a thin layer on dough circle, leaving a 1/2" border around edges. Sprinkle 1/2 cup pecans over butter mixture, pressing to adhere. Cut circle into 12 wedges and roll up wedges, starting at wide end. Place point sides down on a parchment-lined baking sheet. Chill at least 1/2 hour. Repeat procedure with remaining dough (one disc at a time), butter mixture, and pecans.
