1 cup white sugar
2 eggs
1/2 teaspoon vanilla extract
1/2 cup butter or margarine, melted
1/2 cup all-purpose flour
1/3 cup unsweetened cocoa powder
1/4 teaspoon baking powder
1/4 teaspoon salt
1/2 cup miniature chocolate chips
1/2 cup evaporated milk
1 egg yolk
4 (1 ounce) squares semisweet baking chocolate, chopped
6 ounces cream cheese, softened
2 tablespoons seedless raspberry jam
1 cup frozen whipped topping, thawed
2 drops red food coloring (optional)
16 chocolate curls (optional)

1 cup white sugar 2 eggs 1/2 teaspoon vanilla extract 1/2 cup butter or margarine, melted 1/2 cup all-purpose flour 1/3 cup unsweetened cocoa powder 1/4 teaspoon baking powder 1/4 teaspoon salt 1/2 cup miniature chocolate chips 1/2 cup evaporated milk 1 egg yolk 4 (1 ounce) squares semisweet baking chocolate, chopped 6 ounces cream cheese, softened 2 tablespoons seedless raspberry jam 1 cup frozen whipped topping, thawed 2 drops red food coloring (optional) 16 chocolate curls (optional)

Preheat an oven to 350 degrees F (175 degrees C). Line an 8 inch square baking pan with aluminum foil.
In a large mixing bowl, beat the sugar, 2 whole eggs, and vanilla until combined. Mix in butter. In another bowl, combine the flour, cocoa powder, baking powder, and salt; stir into butter mixture, mixing just until incorporated. Fold in the chocolate chips. Pour the batter into the prepared pan.
Bake in preheated oven until a toothpick inserted in the center comes out with moist crumbs attached, 25 to 30 minutes. Cool pan on wire rack.
Whisk together the evaporated milk and egg yolk in a small saucepan. Heat over medium low, stirring constantly, until the mixture is very hot and thickens slightly; do not boil. Place the 4 ounces of chopped semisweet chocolate in a medium bowl, and slowly pour in the hot milk. Stir until the chocolate is melted and smooth. Pour the filling over the cooled brownies; refrigerate until firm, about 2 hours.
Beat the cream cheese with the raspberry jam in a large bowl until smooth. Fold in the whipped topping, and add the food coloring if desired. Top the cooled brownies with the frosting, using a cake comb to create a design. Cut brownies into 16 squares, and then cut each square in half diagonally to form triangles. Garnish with chocolate curls if desired.
