- All‑purpose flour: Creates a tender structure; sift for a lighter batter.
- Butter: Adds richness; melt gently to keep the batter smooth.
- Powdered sugar (glaze): Gives the glaze a smooth, melt‑in‑your‑mouth texture.
- Honey (optional sweetener): A drizzle of honey can deepen the lemon’s sweetness without overwhelming.
