Vanilla Bean Buttermilk Cake

Here is the first recipe that I tried.  I received it from a friend (don't know the orginal source) and have tweeked it a little.

2 1/4 cups cake flour
1 tablespoon baking powder
½ teaspoon salt
1 ¼ cups buttermilk
4 large egg whites
1 ½ cups sugar
1 stick (8 tablespoons or 4 ounces) unsalted butter, at room temperature
1 tbsp Vanilla bean paste

Getting Ready
Centre a rack in the oven and preheat the oven to 350 degrees F. Butter two 9 x 2 inch round cake pans and line the bottom of each pan with a round of buttered parchment or wax paper. Put the pans on a baking sheet.

To Make the Cake
Sift together the flour, baking powder and salt.
Whisk together the milk and egg whites in a medium bowl.
Put the sugar, vanilla bean paste and sugar in a mixer bowl with the paddle or whisk attachment, or with a hand mixer, beat at medium speed for a full 3 minutes, until the butter and sugar are very light.
Add one third of the flour mixture, still beating on medium speed.
Beat in half of the milk-egg mixture, then beat in half of the remaining dry ingredients until incorporated.
Add the rest of the milk and eggs beating until the batter is homogeneous, then add the last of the dry ingredients.
Finally, give the batter a good 2- minute beating to ensure that it is thoroughly mixed and well aerated.
Divide the batter between the two pans and smooth the tops with a rubber spatula.
Bake for 30-35 minutes, or until the cakes are well risen and springy to the touch – a thin knife inserted into the centers should come out clean
Transfer the cakes to cooling racks and cool for about 5 minutes, then run a knife around the sides of the cakes, unfold them and peel off the paper liners.
Invert and cool to room temperature, right side up (the cooled cake layers can be wrapped airtight and stored at room temperature overnight or frozen for up to two months).

This was well received by my family!
