This vintage-style layer cake blends the rich, nutty flavor of peanut butter with a soft, tender crumb thanks to sifted cake flour and brown sugar. The use of both baking powder and baking soda ensures a lofty rise, while milk and vanilla bring moisture and aromatic sweetness. Ideal for frosting or enjoying plain, this cake is a nostalgic nod to mid-century American baking, perfect for family gatherings, birthdays, or a cozy weekend treat.
