Step 1: In a heavy saucepan, combine the brown sugar, sour cream, 2 tablespoons butter and cornstarch; bring to a boil over medium heat, stirring constantly. Remove from the heat; stir in 1/2 teaspoon vanilla.
Step 2: Melt the remaining butter; place in a large bowl. Add ice cream; stir to blend. Add eggs, one at a time, beating well after each addition; stir in the remaining vanilla. In another bowl, mix the flour, cracker crumbs, sugar, baking powder and salt; gradually stir into ice cream mixture.
Step 3: Pour into a greased 13-in. x 9-in. baking pan. Drizzle with half of the sauce. Bake at 350° for 25-30 minutes or until a toothpick inserted in center comes out clean. Cool slightly in pan on a wire rack.
Step 4: Add pecans to remaining sauce; spoon over warm cake (sauce will not cover cake completely). Cool cake in pan.
Step 5: Serve with whipped cream if desired.
