Hi Serena :-) I have found a couple of recipes for Dominican Cake on the internet but I have not tried them. So far, none of them seem to specify the size of the cake pan you should use. Even so, I hope this will help you. Good luck!

DOMINICAN "VANILLA CAKE"
Here is a recipe for the Dominican National Cake. It is a local version of "Pound Cake". Typically it is split in half and filled with fresh pineapple jam and then dusted with powdered sugar or covered with Creole Meringue which can be left naturally white or given a quick browning under the flame of broiler or hand torch.

"BIZCOCHO CRIOLLA"
DOMINICAN CREOLE VANILLA CAKE

CAKE INGREDIENTS
For 2 Cakes

1 LB. Butter
1 LB. Granulated Sugar
10 Whole eggs
1.5 lbs. Cake Flour
1/2 Oz Baking Powder
1/2 Oz Vanilla extract
1 cup Fresh Orange Juice
Dash of salt
TO PREPARE CAKE

Cream butter and sugar together for about 10 minutes at medium high speed using an electric mixer.
Add eggs 5 at a time to the above mixture and beat each addition for about 1 minute or until well incorporated.
Sift all dry ingredients together and then ADD them to the above wet ingredients. At medium speed, mix and combine for 5 minutes.
Then add the vanilla extract and the orange juice and continue to mix for about 2 more minutes.
Bake in a preheated oven at 400 degrees F. If you have a convection oven bake at 350 degrees F.

MERINGUE INGREDIENTS

5 oz whites (about 10 eggs)
10 oz powdered sugar
TO PREPARE MERINGUE

Place egg whites and powdered sugar in a very clean, greaseless and dry mixing bowl and at high speed mix for about fifteen minutes or until the whites become a stiff consistency.
NOTE
The normal ratio of egg whites to powdered sugar, BY WEIGHT is 2 parts sugar to 1 part egg white. So, for example, if you have 5 ozs, of egg whites use 10 ozs. of powdered sugar. Medium size eggs should have about 1/2 an oz. of egg white each but it is best to weigh when using this procedure.

TO SERVE CAKE
Split cake in half and spread with the pineapple filling.
Cover cake with meringue or powdered sugar and serve.
