Apple Pull apart Bread

Combine 1 cup flour, 2 tablespoons sugar, yeast, and salt in a large bowl; blend well. Heat milk and 2 tablespoons butter to 120 degrees F; add egg. Blend well. Add milk mixture to flour mixture; beat at medium speed of an electric mixer until smooth. Stir in enough remaining flour to make a stiff dough. Turn dough out onto a lightly floured surface and knead 4 or 5 times or until smooth and elastic. Cover and let rest 20 minutes. Combine apple, 2/3 cup sugar, pecans, and cinnamon; set aside. Divide dough into halves; cut each half into 16 equal-sized pieces. Shape each piece into a ball and roll out on a lightly floured surface to a 2 1/2-inch circle. Place 1 teaspoon apple mixture in center of circle. Pinch edges together to seal and form a ball. Dip each ball into remaining melted butter. Place 16 balls into a greased 10-inch tube pan. Sprinkle with 1/4 cup apple mixture. Repeat procedure with remaining dough, apple mixture, and butter. Place remaining 16 balls over first layer of balls and sprinkle evenly with remaining apple mixture. Bake at 350 degrees F on lowest rack in oven for 40 minutes or until golden. Let cool 10 minutes; invert onto serving plate. Combine 1 cup powdered sugar, water, and vanilla, stirring until smooth. Drizzle over bread.
