Storage Tips
Wrap leftover cake tightly in plastic wrap or use an airtight container and store in the fridge for up to one week. Let slices come fully to room temperature before serving so the flavors and texture really shine. You can freeze entire unfrosted cake layers for up to three months just wrap well and thaw in the fridge overnight.
Ingredient Substitutions
No buttermilk on hand Just mix regular milk with a splash of lemon juice and let it rest five minutes for a quick homemade version. Any neutral oil can stand in for vegetable oil or try light olive oil for a touch of fruitiness. For gluten free needs swap in a blend of gluten free all purpose flour and check for results.
Serving Suggestions

Serve thick slices with a scoop of vanilla ice cream or a handful of fresh strawberries to balance the richness. Dust the top with cocoa powder or add birthday candles for a classic party look. For an elegant finish drizzle with a little warm ganache just before serving.
