- Pan Choice: A 9-inch square baking pan can also be used. The baking time may be slightly less, so start checking at 20 minutes. 
- Don’t Overmix: The key to a tender cake is mixing the batter until the ingredients are just combined. Overmixing develops gluten and can make the cake tough. 
- Flavor Variations: Add the zest of one orange to the wet ingredients for a bright, citrusy twist, or fold 1/2 cup of fresh blueberries into the batter at the end. 
- Serving Suggestion: This cake is wonderful on its own, but it’s truly sublime when served warm with a dollop of whipped cream or a scoop of vanilla ice cream.
