Method
- Heat oven to 180C/160C fan/gas 4. Line a 20 x 30cm baking tray tin with baking parchment. Put the chocolate, butter and sugar in a pan and gently melt, stirring occasionally with a wooden spoon. Remove from the heat.
- Stir the eggs, one by one, into the melted chocolate mixture. Sieve over the flour and cocoa, and stir in. Stir in half the raspberries, scrape into the tray, then scatter over the remaining raspberries. Bake on the middle shelf for 30 mins or, if you prefer a firmer texture, for 5 mins more. Cool before slicing into squares. Store in an airtight container for up to 3 days.
Cooking notes
Baked goods are unforgiving with rounding — use weights rather than volumes whenever possible, and verify pan capacity if you scale up or down significantly.
For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.
When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.

Cooking aids
Tools to use while you cook this.
Each opens in a new tab so the timer keeps running. The math is auditable on the guide page below each converter, with worked examples and where the numbers come from.
Volume
Tablespoons, teaspoons, cups, ml, fluid ounces — every culinary volume unit, with US/metric/imperial cups handled distinctly.
OpenWeight
Grams, ounces, pounds, kilograms — exact for any ingredient, plus the volume-to-weight conversions for ~40 pantry staples.
OpenTemperature
Fahrenheit, Celsius, gas mark — translate any oven temperature, with notes on conventional vs convection.
OpenCooking time
The cube-root rule for scaling up, the differences between meat / cake / soup geometry, and sensible starting estimates.
OpenPan size
9-inch round vs 8-inch square vs 13×9. The math is surface area, not diameter — and the converter shows you both.
OpenLength
Inches and centimetres — for when a recipe says “cut into 1-inch pieces” and your ruler is metric.
OpenIngredient density
A cup of flour weighs 120 g; a cup of honey weighs 340. The full table of ~40 staples, with sources.
