Method
Each step includes heat, a visible cue, and a recovery.

Step 1 · follow the visible cue
Prepare the measured ingredients
Prepare in separate bowls whole-grain tea biscuits, dark chocolate, and plain yogurt. Match the listed amounts, prepare each for its own cooking time, and keep wet components away from ingredients that need a dry surface.
Look for: Before cooking, confirm whole-grain tea biscuits, dark chocolate, and plain yogurt are evenly prepared, accurately measured, and free of unintended surface water.

Step 2 · follow the visible cue
Build the defining flavour
Develop depth from walnuts, raisins, and cocoa powder. Add them in a deliberate order so strong aromatics soften without burning and delicate notes remain noticeable in Chocolate Biscuit Cake.
Look for: At this stage, check walnuts, raisins, and cocoa powder smell rounded and remain recognisable, with no black flecks, raw spice aroma, or separated fat.

Step 3 · follow the visible cue
Cook with controlled heat
The central technique is simple: coat broken biscuits in a cooled chocolate mixture, press gently to retain pieces, and chill under light weight. Regulate heat and exposed moisture throughout this stage instead of correcting the texture later with extra oil, sugar, or sauce.
Look for: The reliable doneness signal is the slice shows crisp biscuit mosaics, cuts cleanly, and leaves no oily film on the knife. Check the thickest or coolest part rather than judging only the browned surface.

Step 4 · follow the visible cue
Finish and verify the texture
Complete the plate with butter and vanilla. Stop when the slice shows crisp biscuit mosaics, cuts cleanly, and leaves no oily film on the knife, allow only the rest required for the structure to settle, and divide Chocolate Biscuit Cake evenly into eight portions.
Look for: After a short rest, confirm Chocolate Biscuit Cake holds its intended shape and the slice shows crisp biscuit mosaics, cuts cleanly, and leaves no oily film on the knife; no excess liquid, fat, or loose coating collects around the serving plate.
