What is a good food cost percentage for cake slices?

Dessert slices typically run 18-25% food cost, on the lower end for a menu, because baked goods produced in bulk have low per-slice ingredient cost relative to their price.

How much does chocolate quality affect dessert cost?

Significantly — premium or single-origin chocolate can cost multiples of standard cocoa-based products. If a dessert is marketed as premium, its costing should reflect the actual chocolate used, not a generic estimate.

Does slice size affect food cost percentage?

Yes, directly. A cake meant to yield 12 slices that's cut into 10 larger ones raises the ingredient cost per slice by 20%, which needs to be reflected in either the price or a corrected portion standard.

Common Pricing Mistakes

Using low-quality chocolate cost assumptions for a premium-positioned dessert

If the menu markets a dessert as made with premium or single-origin chocolate, the costing needs to reflect that ingredient's actual higher price, not a generic cocoa-based estimate.

Not costing garnish consistently across every slice sold

Berries, sauce drizzle, and whipped cream are individually cheap but compound across dozens of desserts sold nightly into a real, countable cost.

Cutting slices inconsistently from a whole cake

A cake meant to yield 12 slices that's actually cut into 10 larger portions changes the effective cost per slice significantly — standardized cutting guides help control this.
