Instructions
- Preheat oven to 350 degrees. Grease and flour a 13 by 9 inch baking pan.
- Place mashed potatoes into medium bowl. With a whisk, gradually stir in water to form a smooth mixture, do not beat mixture excessively. Cool to lukewarm.
- Sift flour, cocoa powder, coffee granules, baking soda and salt. Place chocolate chips in small bowl with about 1 Tablespoon of the sifted dry ingredients and stir well until chips are coated. Set aside.
- In a large bowl, combine butter, sugar and vanilla. Beat 2 minutes at medium speed. Add eggs, 2 at a time, beating in at a low speed until blended. Increase mixer speed to medium; beat 1 minute.
- At lowest speed, add sifted dry ingredients in 3 additions and mashed potato-water mixture in two additions, beginning and ending with dry ingredients and beating after each addition just until blended. Batter may still appear curdled after all ingredients have ben added -- this is okay. Remove bowl from mixer.
- Fold in chocolate chips.
- Turn batter in prepared pan. Bake 27 to 32 minutes. Sift confectioners' sugar over top just before serving.
