Method

1. Preheat oven to 350° F. Dissolve yeast in warm water, in small bowl; stir in granulated sugar. Let stand for 10 min., or until mixture expands and starts to bubble.
2. Stir together pecans, half of the brown sugar and cinnamon; cut in chilled butter until mixture resembles small peas. Set aside for topping.
3. Beat together remaining brown sugar, softened butter, yogurt and egg on medium speed of electric mixer until mixture is fluffy. Beat in yeast mixture just until blended.
4. Mix flour and baking powder; stir into yogurt mixture just until moistened. Spread or pat dough with floured fingers evenly greased 13×9-inch baking pan (batter will be stiff). Arrange apple slices in rows, overlapping slightly, over batter.
5. Sprinkle topping mixture evenly over apples. Bake 35 to 45 min. or until a wooden pick inserted in centre comes out clean, and apples are tender. Cut into squares and serve warm or cooled.
