In large bowl, combine 1 cup flour, sugar, undissolved yeast,
and salt. Heat milk, water and butter until very warm (120 to 130o
F). Gradually add to dry ingredients. Beat 2 minutes at medium
speed of electric mixer, scraping bowl occasionally. Add eggs and
1 cup flour; beat 2 minutes at high speed, scraping bowl
occasionally. Stir in chocolate morsels and remaining flour to
make a soft batter. Turn into greased 13 x 9 x 2-inch baking pan.
Cover; let rise in warm, draft-free place until doubled in size,
about 1 hour.
Chocolate Nut Topping: In medium bowl, cut 1/2 cup butter into
2/3 cup all-purpose flour until crumbly. Stir in 2/3 cup sugar, 2
teaspoons ground cinnamon, 1 cup semi-sweet chocolate morsels, and
1 cup chopped pecans.
