1 (8 oz.) pkg. cream cheese, softened
2 1/4 c. sugar, divided
1 tsp. cinnamon
4 eggs, divided
3 1/2 tsp. vanilla, divided
1 c. butter
4 oz. unsweetened chocolate
1 1/2 c. flour
1/2 tsp. salt
1 c. chopped nuts

In small bowl of electric mixer, combine cream cheese, 1/4 cup of the sugar, cinnamon, one of the eggs, and 1 1/2 teaspoons of the vanilla. Beat until smooth and set aside.

In small saucepan, melt butter and chocolate over low heat, stirring occasionally; when melted, remove from heat and cool slightly.

In large bowl of electric mixer, combine remaining 2 cups sugar, remaining 3 eggs, remaining 2 teaspoons vanilla, and reserved cooled chocolate mixture; beat on medium speed until well-blended.

Beat in flour and salt on low speed; stir in nuts. Spread half the chocolate batter in greased 9 inch square baking pan.

Spread prepared cheese filling on top and cover with remaining half of chocolate batter. Gently swirl spoon through batter to give a marbled effect.
