Frequently Asked Questions

Greek yogurt or buttermilk can substitute, though the texture will be a touch lighter.
→ How long does the cake stay fresh?
Stored in an airtight container, it stays moist for up to 4 days at room temperature.
→ Can I make this gluten‑free?
Swap all‑purpose flour for a 1‑to‑1 gluten‑free blend; the crumb remains tender.
