A cost rule that survives inflation
For this New Zealand batch, plan the eight-serving yield around ripe bananas, whole-wheat flour, and eggs. Buy plain yogurt, walnuts, and brown sugar only in the amounts needed here, then reserve canola oil and baking powder for the finish so none is lost to long cooking or oversized portions.

- 220 gwhole-wheat flour

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

Step 1 · follow the visible cue
Prepare the measured ingredients
Start with accurately portioned ripe bananas, whole-wheat flour, and eggs. 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: Nothing should enter the pan until ripe bananas, whole-wheat flour, and eggs are evenly prepared, accurately measured, and free of unintended surface water.

Step 2 · follow the visible cue
Build the defining flavour
Wake up the characteristic aromas in plain yogurt, walnuts, and brown sugar. Add them in a deliberate order so strong aromatics soften without burning and delicate notes remain noticeable in Banana Cake.
Look for: The flavourings are correctly handled when plain yogurt, walnuts, and brown sugar 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
Cook only as far as needed to mash bananas coarsely, fold the batter just until combined, and bake one shallow layer with no heavy butter icing. Regulate heat and exposed moisture throughout this stage instead of correcting the texture later with extra oil, sugar, or sauce.
Look for: End the main cook as soon as the cake springs back and shows small banana pieces without a dense wet stripe at the base. Check the thickest or coolest part rather than judging only the browned surface.

Step 4 · follow the visible cue
Finish and verify the texture
Once the heat is off, bring in canola oil and baking powder. Stop when the cake springs back and shows small banana pieces without a dense wet stripe at the base, allow only the rest required for the structure to settle, and divide Banana Cake evenly into eight portions.
Look for: Portion the recipe once Banana Cake holds its intended shape and the cake springs back and shows small banana pieces without a dense wet stripe at the base; no excess liquid, fat, or loose coating collects around the serving plate.
