Trisha Yearwood's Key Lime Cake

I had family over for dinner last evening.  I had seen this cake on Trisha Yearwood's show on Food Network.  My menu was Mexican food, so I thought this would be kind of 'Margarita-ish' and would go well.  It was well received.  I made a few adjustments to her recipe but it is a good cake.

TRISHA YEARWOOD'S KEY LIME CAKE

Cake:
1-1/3 cups granulated sugar
2 cups all purpose flour
1/2 teaspoon salt
1 teaspoon baking powder
1 teaspoon baking soda
1 3 oz. package lime-flavored Jello, dry mix
 3/4 cup vegetable oil (her recipe calls for 1-1/2 cups which I think is way too much)
3/4 cup orange juice
1 tablespoon lemon juice
1/2 teaspoon vanilla
5 large eggs slightly beaten

Glaze:
1/2 cup lime juice
1/2 cup powdered sugar

 Icing:
1/4 cup softened butter
1 8 oz. package cream cheese, softened
4 cups powdered sugar
1/2 teaspoon vanilla

Preheat the oven to 350 degrees.  Grease and flour a 9 x 13 pan or three 9 inch layer pans.

In a large mixing bowl, mix the gelatin, granulated sugar, flour, salt, baking powder and baking soda. Stir to mix well. Add the oil, orange juice, lemon juice, vanilla, and eggs. Mix until well combined. Pour the batter evenly in the pan and bake for 35 to 40 minutes. Test for doneness by lightly touching the tops or inserting a toothpick. Cool the cake in the pan for 5 minutes then turn out onto a cooling rack.

For the glaze:
While the cake is still hot, mix the lime juice and confectioners' sugar together well. Pierce the cake with a fork to allow the glaze to soak in and pour it over the cake on the cooling rack. Allow cake to cool completely as you prepare the icing.

For the icing:
Cream the butter and cream cheese and vanilla. Beat in the confectioners' sugar until mixture is smooth and easy to spread. Spread the icing on the top and sides of the cake.
