Chocolate brownies: how much it costs to make, per portion

By · Updated

A 20×30 cm tray cut into 16 fudgy cocoa brownies. Made with cocoa powder rather than bar chocolate, which keeps the cost down and the texture dense. Costed from JJ Foodservice wholesale prices dated 9 October 2026. Vanilla is from our 7 September Tesco price.

Method

  1. Heat the oven to 180 °C (160 °C fan) and line a 20×30 cm tin.
  2. Melt the butter, stir in the sugar and cocoa, and let it cool for a few minutes.
  3. Beat in the eggs and vanilla, then fold in the flour and salt until just combined.
  4. Bake for 20-25 minutes, until the top is set and shiny but the middle still has a slight wobble. Cool fully in the tin before cutting.

Costing notes

A bar-chocolate brownie typically uses 200 g or more of dark chocolate; using cocoa alone makes this tray cheaper and still gives a fudgy result. Cocoa is the most expensive ingredient here per gram, so weigh it.

At 16 brownies a tray, each comes to about 33p of ingredients; café brownies commonly sell at £2.50-£3.50.

Where the prices came from

JJ Foodservice collection prices as shown on its public search pages on 9 October 2026 (delivery runs about £1-2 a case higher). A few lines JJ did not list in that day's searches reuse the dated prices already on our other starter recipes (7 September 2026, JJ Foodservice or Tesco retail, marked on each line). JJ does not label VAT on most lines: raw food is zero-rated in the UK, while soft drinks, alcohol, confectionery and some ingredients carry standard-rate VAT. Your supplier's price is the one that matters: open the recipe and type it in.
