Lemon Crumb Bars

I found this recipe years ago and am now copying it here from our family cookbook binder. Enjoy!

Lemon Crumb Bars

Ingredients:

• 1 (18 ¼ oz.) pkg. lemon cake mix
• ½ cup butter, softened
• 1 egg  
• 3 egg yolks
• 2 cups finely crushed saltine crackers (2 cups=1/4 lb)
• 14 oz can sweetened condensed milk
• 1/2 cup lemon juice 

Directions:

1. Preheat oven to 350 degrees.  
2. In a large bowl, beat cake mix, butter and 1 egg with mixer until crumbly.  
3. Stir in saltine cracker crumbs.  Reserve 2 cups crumb mixture.  
4. Press remaining crumbs on bottom of greased 9x13 pan.  
5. Bake 15-20 minutes or until golden brown.  
6. With mixer or wire whisk, beat 3 egg yolks, sweetened condensed milk (NOT EVAPORATED MILK) and lemon juice.  
7. Spread over prepared crust.  Top with reserved crumb mixture.  
8. Bake 25 minutes longer, or until set and top is golden.  Cool.  (You may want to dust the bars with powdered sugar.)  
9. Refrigerate within 2 hours.  Cut into bars.  Store covered in refrigerator.  Better if served slightly warm, so warm each bar in the microwave for a few seconds.
