Oatmeal Cake

Oatmeal cake is a Southern dessert that doesn’t get the love it deserves. This version trims the sugar with a liquid substitute and uses molasses as the primary sweetener, which gives the cake its dark color, deep flavor, and faint butterscotch character. Egg whites instead of whole eggs trim the cholesterol without sacrificing the structure.

Dry buttermilk powder is the under-the-radar ingredient that does the heaviest work. Activated by water in the batter, it brings the same tang and tenderizing acid you’d get from fresh buttermilk, but in a form that keeps in the pantry for months. Combined with baking soda, it provides the lift this otherwise modest cake needs to stay tender instead of going dense.

The rolled oats go in last and stay mostly intact through the bake. Each bite has visible flecks of toothy oat that give the cake its signature texture, somewhere between a coffee cake and a baked oatmeal. Raisins fold in for soft pockets of sweetness. Don’t skip them. They’re what tip the cake from utilitarian into homey.

Pro Tips

• Use room-temperature egg whites and margarine. Cold ingredients won’t beat to the same volume and the cake comes out denser.
• Add the second ¼ cup of water with the oats. Cold water there hydrates the oats just enough to soften them in the bake without turning the batter watery.
• Cut the cake into 16 squares, not 9 large pieces. Smaller portions keep the calorie-conscious framing this recipe was built around.
• Top each square with a dollop of whipped topping or a sprinkle of toasted walnuts for a finishing touch.

Variations

• Stir in a half cup of chopped pecans or walnuts for crunch.
• Swap raisins for dried cranberries or chopped dates for a sharper or sweeter fruit profile.
• Skip the sugar substitute and use a full quarter cup of brown sugar for a richer, more traditional cake.
