2 1/4 cups all-purpose flour
2 teaspoons baking powder
1/4 teaspoon salt
3/4 cup (1 1/2 sticks) butter, softened
1 cup granulated sugar
1/4 cup packed brown sugar
2 teaspoons vanilla extract
3/4 cup milk
1 cup chocolate mini-chips
Three Way Chocolate Jazz
1 cup heavy cream
1/3 cup light corn syrup
4 ounces semisweet chocolate ( 2/3 cup chips)
4 ounces bittersweet chocolate, chopped
1 ounce milk chocolate, chopped
1 cup powdered sugar
2 tablespoons butter, softened
Preheat oven to 325 degrees F.
Line a 10 x 15-inch jellyroll pan with parchment baking paper, lightly grease and flour paper.
Stir together flour, baking powder and salt; set aside.
In large mixer bowl, beat butter, sugars and vanilla until light. Beat in eggs 1 at a time. Add flour mixture alternately with milk, beat at medium speed about 2 minutes. (Mixture may have a curdled appearance.) Stir in chips.
Spread batter in prepared pan and smooth top. Bake, turning pan in oven once or twice to assure even baking 30 to 35 minutes or until just firm to the touch. Let cool in pan 15 minutes.
Invert onto a rack; remove paper, and cool completely. Cut cake in half to make 2 rectangles, each 7 1/2 x 10 inches.
To prepare Chocolate Jazz: In a heavy saucepan, bring cream and corn syrup to a boil over medium heat, stirring often.
Remove from heat, add semisweet and bittersweet chocolates. Let stand for a minute, then stir until chocolates are melted. Do not beat mixture.
Measure about 2 tablespoons of the hot mixture into a small bowl, stir in milk chocolate. Pour into a resealable plastic bag, and set aside to use for writing on the finished cake.
Measure 1/2 cup of the cream mixture into a mixing bowl, beat in powdered sugar and butter. Beat until smooth, set aside to use as filling.
To assemble cake: Arrange 1 rectangle of cake on a serving platter.
Spread filling over cake, smooth top. Place second cake layer on top.
Pour remaining cream mixture over cake to glaze. (If mixture has thickened, re-warm just to pouring consistency.) Let glaze cover top and drizzle down sides of cake.
If milk chocolate mixture has become firm, hold the bag in your hands until chocolate is very soft. Cut a tiny hole in one corner of bag, and pipe your message onto glazed cake.
Yield: 15 servings.
