Notes
- Jelly roll pan: To get the ideal cake-to-frosting ratio, bake this cake in a 10-inch by 15-inch jelly roll pan (I love this one by OXO).
- Yield: This recipe makes 24 squares, 2 1/2-inch by 2 1/2-inch each, cut in a 4x6 configuration.
- Storage: Store covered at room temperature for 1 to 2 days or refrigerate for up to 1 week.
