Southern Butter Cake

Why This Southern Butter Cake Works

During mixing, the soft butter and sugar trap a lot of tiny air pockets as they are beaten together. Those little pockets stay inside the batter when the eggs, flour, and buttermilk go in. In the oven, the air and steam inside those pockets expand and the baking powder and baking soda start to lift the batter. That is what makes the cake rise and stay light instead of dense.

As the cake bakes, the flour sets and holds that shape, while all the butter keeps the crumb soft instead of dry. Buttermilk keeps the batter loose and moist, and its slight tang keeps the cake from tasting flat. In the warm cake, the glaze of melted butter, sugar, water, and vanilla slowly soaks down through the holes. The warm crumb drinks it in, so the outside gets a thin sugary shell and the inside stays very moist and buttery, even after the cake cools.

Mistakes To Avoid

Letting the cake overbake at 325°F dries it out, especially around the edges and top. The sugar and butter start to brown too far and the crumb tightens, so instead of a soft, moist slice, the cake turns firm and crumbly with a tough crust.

Creaming the butter and sugar too little leaves the mixture heavy and grainy. Without enough air beaten in at the start, the batter doesn’t rise well in the oven, and the finished cake comes out dense with a tight, almost gummy texture instead of a light, tender crumb.

Pouring the glaze on a cooled cake keeps it from soaking in. The butter-sugar mixture just sits on the surface and hardens in patches, so the outside becomes overly sweet and sticky while the inside stays plain and a bit dry.

Removing the cake from the bundt pan while it is still warm causes it to break apart. The crumb has not set fully, so chunks stick to the pan and the cake comes out in pieces instead of holding its shape.
