Bake a Cake From Scratch

I used this recipe to make a cake from scratch for my mom's birthday

Ingredients

1 cup butter
2 cups white sugar
1 teaspoon vanilla extract
4 eggs
3 teaspoons baking powder
3 cups all-purpose flour
1 cup milk
1 pinch salt
Directions

1. Preheat oven to 350 degrees F (175 degrees C). Grease and flour one 9x13 inch pan or three 8 or 9 inch round layer cake pans. I only sprayed Pam, didn't use flour. Wish I had; it would have made it easier to get out of the pans once cool. I used two 9 inch round layer cake pans. 
2. Cream the butter and sugar together until smooth and fluffy. Mix in the vanilla extract. 
3. Separate the eggs and set the egg whites aside. Add the egg yolks one at a time to the creamed mixture, beating after each one. 
4. Measure the baking powder into the flour, sift a little of the flour into the creamed mixture. Continue adding the flour and the milk alternately, while continually beating the mixture. Beat the cake batter until a few air bubbles show. I had never had to look for air bubbles before. I guess this was to beat air into the batter, to make it fluffy. Had to do my best here. 
5. Beat the 4 egg whites with a dash of salt until stiff. This was really hard. Though I did use a hand mixer, I didn't get them completely stiff. Perhaps because there was some yolk still in the bowl, perhaps I didn't do it long enough. Gently fold egg whites into the batter. Pour batter into prepared pan(s). 
6. Bake at 350 degrees F (175 degrees C) until cake(s) test done, approximately 25 to 35 minutes. 

Overall, the cake got rave reviews.  Jared and I thought it could have been dough-ier.  I guess all those air bubbles aren't up our alley.  Next time we will try this cake.
