Best Lemon Sheet Cake

Ingredients:

1 Duncan Hines moist deluxe lemon cake mix
1 c buttermilk
1 3oz. lemon instant pudding mix (dry)

Icing:

4 cups confectioner's sugar
1/3 cups bottled lemon juice
3 Tbsp vegetable oil
3 Tbsp water

Directions:

1. In large bowl, stir together dry cake mix and pudding mix. In another bowl, combine all wet ingredients and eggs that the cake mix calls for plus the buttermilk.(where your box reads the amount of water (1 1/3 cup usually), put in 1 cup water and 1/3 cup lemon juice to make the cake even more lemon tasting, if you like) Beat with mixer until blended. Add to dry mixture and beat until combined.
Bake in a greased 9x13 baking pan in a preheated 350 degree oven for the time the cake mix box calls for...depending on your oven. It will require a couple minutes longer baking time than cake mix box calls for because of the extra moisture produced by the milk. Stick a toothpick in the center to check for doneness.

2 Icing: Combine water, oil, powdered sugar and lemon juice with a mixer until smooth. Add one more tablespoon of water if consistency isn't saucy. "Glaze" the cake when just a little cooled. Do not over glaze it because the icing is sweet. Just a THIN layer is required
