Recipe(tried): Ukrainian Sand Babka Butter Cake

Hi Nina here is a recipe that sounds like what you might be looking for.

UKRAINIAN SAND BABKA BUTTER CAKE

In popular usage the name "babka" refers not only to yeast-raised cake breads but also to butter cakes and various light, egg-rich dishes. This babka has a fine, grainy texture from which its name is derived.

3/4 cup sifted all purpose flour
1 cup sifted potato flour
2 tsp. baking powder
1-1/4 cups butter
2-1/4 cups confectioners' sugar (sometimes called powdered sugar or icing sugar)
6 eggs, separated
Grated rind of 1 lemon
Grated rind of 1 orange
Juice of 1/2 lemon

Sift the first 3 ingredients together 3 times.

Cream the butter, add the sugar gradually, and continue creaming until very smooth. Add the egg yolks, one at a time, and beat until the mixture is very light. Beat in the lemon rind, orange rind, and lemon juice. Stir in the flour. Beat the egg whites until stiff and fold them into the batter.

Butter and sprinkle with fine bread crumbs a 9-inch cake pan, or tube pan and spoon batter into the pan.

Bake in a moderate oven 375 degrees F. for 10 Minutes, then LOWER the temperature to 350 degrees F. and continue baking for about 35 minutes. Remove the babka from the pan and cool it on a cake rack.
