I found this recipe in a magazine. I have not tried this recipe, but I'm posting it for safe keeping.

Ingredients

• 3⁄4 cup all-purpose flour
• 1⁄3 cup cocoa powder
• 1⁄2 teaspoon baking powder
• 1⁄4 teaspoon salt
• 2  ounces  semisweet chocolate, chopped
• 2  tablespoons unsalted butter
• 2  tablespoons low-fat sour cream
• 1  tablespoon  low calorie  chocolate syrup, plus additional for drizzling
• 1 3⁄4 teaspoons vanilla extract

• 1  egg white
• 1  cup sugar
• 1  quart  vanilla frozen yogurt
• 1⁄4 cup  glazed walnuts, chopped (optional)
• 9  maraschino cherries (optional)

Directions

1. Heat oven to 350. Line an 8-inch square baking dish with foil so it hangs over sides; coat spray and set aside.
2. In a small bowl, blend flour, cocoa, baking powder and salt.
3. In a medium-size microwave-safe bowl, microwave chocolate and butter for 40 seconds until melted, stirring halfway through. Stir until smooth, heating in 15 second increments if needed.Cool 2 minutes, then whisk in sour cream, chocolate syrup, vanilla, egg, egg white, and sugar. Stir in flour mixture.
4. Spread batter into prepared pan and bake at 350 for 25-28 minutes or until a toothpick inserted in the center comes out clean. Remove brownie from pan using foil handles. Cut into squares and top each with 1 scoop frozen yogurt, drizzle with chocolate sauce and finish with chopped nuts and cherry, if desired.
