Chocolate Cinnamon Buns: Vintage Ad & Recipe

I'm a sucker for Vintage Ads and Recipes. Since it's Saturday morning, and this might be the last day I have my ovens for a week or so, I thought I'd post this Vintage Ad & Recipe for Chocolate Cinnamon Buns. I know it's not National Cinnamon Bun Day (October 4), but these are worth making. This is a vintage Betty Crocker Gold Medal Flour Advertisement and Recipe.

Chocolate Cinnamon Buns

3/4 cup warm water (not hot - 110 to 115 degrees)
1 package active dry yeast
1/4 cup shortening
1 teaspoon salt
1/4 cup sugar
1 egg
1/3 cup cocoa  (use DARK cocoa for richness)
2 and 1/4 cups sifted flour
1 Tablespoon soft butter
1 and 1/2 teaspoons cinnamon
3 Tablespoons sugar
chopped pistachio nuts (or almonds or pecans)

In mixer bowl, dissolve yeast in warm water. Add shortening, salt, sugar, egg, cocoa and 1 cup flour. Beat 2 minutes, medium speed on mixer or 300 vigorous strokes by hand. Scrape sides and bottom of bowl. Stir in remaining flour; blend well. Scrape sides of bowl.

Cover with cloth; let rise in warm place (85 degrees) until double in bulk, about 1 hour. (If kitchen is cool, place dough on rack over bowl of hot water; cover completely with towel.) Stir down by beating 25 strokes. Turn soft dough out on well floured cloth-covered board. Roll into rectangle, 12 x 9". Spread with butter; sprinkle with cinnamon-sugar mixture. Roll up, beginning at wide side. Pinch edge into roll. Cut 12 pieces. Place in greased 9" square pan. Let rise in warm place (85 degrees) until double, about 40 minutes.

Heat oven to 375 degrees (quick mod.). Bake 25 minutes. Remove from pan, frost top immediately with icing (3/4 cup sifted confectioners' sugar moistened with cream or milk to spreading consistency.) Sprinkle with chopped nuts. Serve warm.
