Lemon Crumb Bars

From the kitchen of: Nela
Thank you for the great recipe, Nela. It was delicous! I love the fact it has cracker crumbs in it! And I love the lemon flavour!

Ingredients:
1 package (18-1/4 ounces) lemon cake mix
1/2 cup cold butter
1 egg
2 cups crushed saltines (about 60 crackers)
3 egg yolks
1 can (14 ounces) sweetened condensed milk
1/2 cup lemon juice

Directions:
In a large bowl, beat the cake mix, butter and egg until crumbly. Stir in cracker crumbs; set aside 2 cups for topping.
Press remaining crumb mixture into a 13-in. x 9-in. baking dish coated with cooking spray. Bake at 350° for 18-20 minutes or until edges are lightly browned.
In a small bowl, beat the egg yolks, milk and lemon juice. Pour over crust; sprinkle with reserved crumb mixture. Bake 20-25 minutes longer or until edges are lightly browned. Cool on a wire rack. Cut into bars. Store in the refrigerator. Yield: 2 dozen.
