Step 1

To make the cake, preheat the oven to 325 degrees Fahrenheit. Grease the bottom of a 10-cup capacity tube pan and coat with flour.

Step 2

In a large mixing bowl, beat together shortening, margarine and sugar at medium speed until light and fluffy, about 5 minutes. Beat in the eggs, one at a time, until well-combined.

Step 3

Add in the soda alternately with the sifted flour. Beat until smooth and lump-free. Stir in the orange flavoring and vanilla extract.

Step 4

Pour the batter into the prepared tube pan. Bake for 1 hour and 10 minutes, or until the top is golden, and a toothpick inserted into the center comes out clean.

Step 5

Flip the pan over onto a wire rack. Let the cake cool inside the pan for about 10 to 15 minutes.

Step 6

Meanwhile, prepare the frosting. In a large mixing bowl, beat together margarine and cream cheese at medium speed until light and fluffy, about 3 minutes.

Step 7

Add powdered sugar, orange flavoring, and vanilla. Beat until the frosting is smooth and spreadable.

Step 8

Loosen the sides of the cake with a knife and release it from the pan. Spread frosting over the warm cake.
