Marble Cheesecake Squares from Cooking Light

I just came across this recipe from Cooking Light ... cheesecake is one of my favorites ... and these squares sound fantastic!

MARBLE CHEESECAKE SQUARES
If you've forgotten to set out the cream cheese to soften, arrange the unwrapped blocks in a single layer in a large bowl, and microwave at HIGH a minute or until slightly soft.

1 cup chocolate graham cracker crumbs (about 9 cookie sheets)
Cooking spray
1 tablespoon butter, melted
2 (8-ounce) blocks fat-free cream cheese, softened
1 (8-ounce) block 1/3-less-fat cream cheese, softened
1 cup sugar
3 tablespoons all-purpose flour
1 tablespoon vanilla extract
3 large egg whites
1 large egg
1 ounce semisweet chocolate

Preheat oven to 325°.

Place crumbs in a 9-inch square baking pan coated with cooking spray; drizzle with butter. Toss with a fork until moist. Press into bottom of pan. Bake at 325° for 8 minutes; cool on a wire rack.

Place cheeses in a large bowl; beat with a mixer at high speed until smooth. Add sugar and flour; beat well. Add vanilla, egg whites, and egg; beat until well blended. Pour cheese mixture into prepared pan.

Place chocolate in a small microwave-safe bowl; microwave at high 1 1/2 minutes or until soft, stirring after 45 seconds (chocolate should not completely melt). Stir until smooth. Drop melted chocolate onto cheese mixture to form 9 mounds. Swirl chocolate into batter using the tip of a knife. Bake at 325° for 35 minutes or until almost set. Cool on a wire rack. Cover and chill at least 4 hours.
