DIRECTIONS

In a small bowl, dissolve yeast in warm water. In a large bowl, combine the flour, 1 tablespoon sugar and salt. Cut in 2 tablespoons of the butter until crumbly. Add the milk, egg yolk and yeast mixture; stir well. Cover with plastic wrap; refrigerate for at least 4 hours or overnight.
    Turn dough onto a lightly floured surface. Roll out into a 10-in. x 6-in. rectangle. Melt remaining butter; brush butter to within 1/2 in. of edges. Combine the brown sugar, cinnamon and remaining sugar. Sprinkle over dough, then sprinkle with chocolate chips.
    Roll up jelly-roll style, starting with a short side; pinch seam to seal. Cut into 1-in. slices; place cut side down in a greased 8-in. square baking dish. Cover and let rise in a warm place until doubled, about 1-1/2 hours.
    Bake at 375° for 15-18 minutes or until golden brown. In a small bowl, combine the confectioners' sugar, butter, vanilla and enough milk to achieve drizzling consistency; drizzle over warm rolls. Serve warm. Yield: 6 rolls. Editor's Note: Rolls may be frozen for up to 2 months. Reheat in the microwave before serving if desired.
