1Heat oven to 325°F. Spray 8 (6-oz) individual baking dishes (ramekins) with cooking spray. Sprinkle sides of dishes with cocoa. Place on cookie sheet.
2In 1-quart saucepan, melt chocolate chips and butter over low heat, stirring frequently. Remove from heat; cool completely.
3In large bowl, beat granulated sugar, the eggs and coffee powder with electric mixer on high speed 3 minutes. Add cooled chocolate mixture, beating on low speed just until blended. Divide batter evenly among baking dishes.
