3 cups Cake Flour
1 Teaspoon of Baking Powder
1 Teaspoon of Baking Soda
2- 1/2 cups sugar
1 cup unsalted butter (2 sticks of butter)
at room temperature
1 Teaspoon Vanilla Extract
5 large eggs( separate eggs from yolks)
1 cup Buttermilk
1-1/4 cup mashed or pureed
Pinch of Salt
Teaspoon Red Food Coloring (optional)
Preheat oven to 325 F. You can preheat it to 350 F and lower the temperature to 325 when you place the cakes in the oven.
I like to bake at lower temperatures. Which require a longer period of baking. But if you
go to a higher temperature keep in mind it will take less time. I would not go higher than 350.
The baking time can change too depending on the size of the pan.
Spray (or butter and flour) 2 pans. I used two 8''x 3 pans.
Sift flour, baking powder. baking soda and salt into medium bowl. Set aside.
Using an electric mixer, cream together butter and 2 cups of the sugar.
Save the rest of the sugar for later.
Add eggs yolks one at a time, beating until well blended after each one.
Add the vanilla.
Add dry ingredients in small additions to butter/sugar mixture alternately with the buttermilk, beginning and ending with flour mixture.
Beat at low speed just until blended after each addition.
Mix in the Red food color (optional), and fold the strawberries in
Strawberries can be smashed or pureed.Set it aside.In a clean dry grease free bowl, mix egg whites with a wisk attachment.
Beat until peaks are stiff but not dry and add the 1/2 cup of sugar you saved to the egg white mixture.
Mix a bit more to make sure the sugar is mixed and the peaks stay stiff.
Fold the egg whites in the butter mixture. I do this in 3 steps.
Pour batter into prepared pans. Bake cakes until tester inserted into center
comes out clean, about 55 minutes.
The amount of time really depends on the pans you use anf your oven. Cool cakes in pans for 10 minutes. Turn cakes out and seal them in plastic well.
Place the cakes in the refrigerator and let them cool well.
I leave them at least over night.
I recommend to eat the cake at room temperature.
