Frequently asked questions
Planning a wedding cake baker in Napa
How much does a wedding cake cost in Napa?
Wedding cakes in Napa usually price by the slice — commonly $4–$9 — so a 120-guest cake often lands between $500 and $1,000. Detailed sugar work and metallic finishes raise the number; many couples pair a smaller display cake with sheet cakes to serve everyone.
How does Lazo rank wedding cakes & desserts in Napa?
Rankings come from the Lazo Score — verified reviews weighted for recency — and are never sold. Vendors without verified reviews yet start at the community baseline of 65 and earn their score as verified reviews arrive.
