1. Beginner-Friendly 30th Birthday Cake Ideas
Classic White Frosted Cake with Gold Accents
A timeless choice, this cake features a smooth white buttercream finish accented with delicate edible gold leaf. It requires minimal tools — an offset spatula, bench scraper, and a small paintbrush for applying the gold leaf.

Simple to frost and decorate, yet elegant enough to impress. Add fresh or faux flowers to personalize it.
Pro tips:
- Crumb coat before applying the final frosting layer for a clean finish.
