COFFEE 7-MINUTE FROSTING2 egg whites, unbeaten
1 1/2 cups sugar
Dash of salt
1/3 cup water
2 teaspoons light corn syrup
2 teaspoons Instant Maxwell House Coffee
1 teaspoon vanilla
Combine egg whites, sugar, salt, water, corn syrup, and Instant Maxwell House in top of a double boiler. Beat with rotary egg beater or electric beater about 2 minute, or until thoroughly mixed. Cook over rapidly boiling water, beating constantly with rotary egg beater (or at high speed of electric beater) 7 minutes, or until frosting will stand up in stiff peaks. (Stir frosting up from bottom and sides of pan occasionally with rubber scraper, spatula, or spoon.)
Remove from boiling water. Add vanilla; beat 1 minute, or until thick enough to spread.
Makes enough frosting to cover the tops and sides of two (9-inch) layers, or the top and sides of a (13x9x2-inch) cake, or tops of about 16 large cupcakes
