Position a rack in center of oven and preheat oven to 375 degrees F. Lay a sheet of phyllo on a clean work surface. Lightly brush sheet with butter. Sprinkle with 2 1/2 tablespoons bread crumb mixture. Layer remaining 7 sheets phyllo over first, buttering and sprinkling each one with bread crumb mixture. Spoon apple compote evenly down long side of phyllo, about 2" from bottom edge and 1" in from both sides. Fold bottom edge and side flaps over filling and roll up phyllo jelly roll-style.
Transfer strudel to baking sheet and brush it lightly with melted butter. Bake for 30 to 35 minutes, or until crisp and golden.
Remove strudel from oven and let cool on the baking sheet on a wire rack for 10 minutes. Dust with confectioners' sugar and serve, sliced, with whipped cream.
