What is Recipe Yield?

Let's use a real example: your chocolate layer cake recipe. You mix 400g flour, 250g sugar, 200g butter, 4 eggs (roughly 200g), 100g cocoa powder, 150g milk, and 10g baking powder. Before you bake, you weigh the finished batter: 1,310g. The oven spring and water loss during baking means your finished cake weighs 950g—that's your yield. This is not guesswork. You need the actual number because it determines your portion costs. Why does yield matter? Because two bakers can use identical ingredients but get different yields. One baker's chocolate cake comes out at 950g. Another's comes out at 920g due to oven temperature, mixing time, or pan size. The baker with the 920g yield is actually losing money on every cake if they're using the same pricing as the 950g baker. You can't price accurately without knowing your exact yield. Yield also changes when you scale recipes. A 24-cupcake recipe has a specific yield (let's say 720g of batter, which makes 24 cupcakes at 30g each). If you scale that recipe to 150 cupcakes, your yield scales too—now you're making 937.5g of batter. But your cost per cupcake stays the same because the ingredient ratio doesn't change. The yield is your anchor point for all your costing. Here's the practical part: you measure yield once per recipe, then you use it forever. Weigh your finished batter or dough before baking, then weigh the finished product after cooling. The difference tells you your water loss. Write that number down. It's the foundation of every price you quote.
