In the bowl of a stand mixer (or in a
large bowl using an electric mixer)
cream together the butter
and sugar until creamy and well-
combined.

Add eggs, one at a time, beating
well after each addition

Stir in vanilla extract.

In a separate, medium-sized bowl,
whisk together flour, baking powder,
and salt.

Using a spatula and gently hand-
mixing, alternate adding flour
mixture and buttermilk to the butter
mixture, starting and ending with
flour mixture and mixing until just
combined after each addition. The
batter should be smooth and
completely combined, but avoid
over-mixing.

Put it into your
prepared cake pans, and bake on
350F for 30-35 minutes.
When the cake is done, the surface
should spring back to the touch and
a toothpick inserted in the center
should come out mostly clean with
few moist crumbs (no wet batter).

Allow cakes to cool in their cake
pans for 5 minutes
