1 (18.25 ounce) package white cake mix
3/4 cup vegetable oil
1 cup lemon-lime flavored carbonated beverage
2 (3 ounce) packages instant pistachio pudding mix
2 (1.3 ounce) envelopes whipped topping mix
1 1/2 cups milk
Beat cake mix, oil, soda, eggs, and first package of pudding until smooth. Pour batter into greased 9 x 13 inch pan.
Bake at 325 degrees F (165 degrees C) for 45 minutes, or cake tests done.
Beat Dream Whip, milk, and pudding until stiff; pour over cooled cake. Refrigerate.
Cake is very moist and easy to make. I didn't really see the need for all the oil and eggs. Overall the cake is good. I used fat free Cool Whip instead of the dry Dream Whip for the frosting/topping.
