Ann, here's one from their website: Chocolate-Espresso Chiffon Cake
(the photo doesn't look anything like a bundt cake, so this may not be the one you're searching for. Another option is to check your local libary system. They'll have back-copies of magazines.)
Ingredients:
8 eggs
4 tsp. espresso powder or instant coffee crystals
3/4 cup water
2 cups all-purpose flour
1-1/2 cups sugar
1 Tbsp. baking powder
1 tsp. salt
1/2 cup cooking oil
1 tsp. vanilla
3 oz. bittersweet chocolate, grated
1/2 tsp. cream of tartar
1 recipe Espresso Whipped Cream
Directions
1. Separate eggs, discarding 3 of the yolks or saving for another use. Let eggs stand at room temperature 30 minutes. Preheat oven to 325 degrees F. Dissolve espresso in water; set aside.
2. In large bowl stir together flour, sugar, baking powder, and salt; make well in center. Add oil, the 5 egg yolks, dissolved espresso, and vanilla. Beat on low until moistened; beat on medium-high 4 to 5 minutes or until satin smooth. Stir in grated chocolate.
3. Wash and dry beaters. In 4-quart bowl beat egg whites and cream of tartar on medium-high until stiff peaks form (tips stand straight). Pour chocolate batter in thin stream over surface of whites; fold to blend. Spoon in ungreased 10-inch tube pan.
4. Bake 60-70 minutes or until top springs back when lightly touched near center. Invert pan to cool. Carefully loosen sides; remove from pan. Serve with Espresso Whipped Cream. Makes 14 servings.
5. Espresso Whipped Cream: In chilled bowl combine 1 cup whipping cream, 1 Tbsp. sugar, 1/2 to 1 tsp. espresso powder or instant coffee crystals, and 1/2 tsp. vanilla. Beat until soft peaks form.
