Chef’s Tips
- For us, cinnamon is essential to a honey bun cake, but if you want to go all out fall, you can make a pumpkin spice swirl instead!
- Store any leftovers in the pan at room temperature, tightly covered with food wrap. Or, transfer it to an air-tight container. Regardless, it should keep well for up to 3 days.
