1 box pudding recipe lemon cake mix
3 eggs
2 tablespoons flour
1 tablespoon plus 1 teaspoon vegetable oil
16 ounces dairy sour cream
1/2 cup granulated sugar
1 teaspoon lemon juice
1 cup milk
2 drops yellow food coloring
1 (21 ounce) can blueberry pie filling

Preheat oven to 300 degrees F. Measure out 1 1/2 cups dry cake mix; set aside.

Stir together remaining dry cake mix, 1 egg, flour and oil in a large bowl. Press this crumb mixture evenly into bottom and three-quarters of the way up the sides of a 13 x 9 x 2-inch pan.

In the same bowl, blend sour cream, sugar, 2 eggs, reserved cake mix, and lemon juice for 1 minute at low speed. Gradually add milk and food coloring while beating for 2 minutes at medium speed. Pour into crumb crust. Bake at 300 degrees F for 45 to 50 minutes, or until center is firm. Do not overbake. Cool at room temperature for 1 hour.

Top with blueberry pie filling or your favorite pie filling and refrigerate.
