Now scale it. The basic recipe makes 12 crispies. You need 30 for a party. Multiply every ingredient by 30 ÷ 12 = 2.5.
Find the factor, then scale everything
The base recipe makes 12 crispies. Need a different number? Divide what you want by 12 to get the scale factor, then multiply every ingredient by it. 30 crispies → 30 ÷ 12 = 2.5, so everything ×2.5.
The recipe makes 12 crispies. You need 18. By what factor do you scale, and how much chocolate is that?
Don't scale cooking time by the same factor — a double batch of cookies doesn't bake for twice as long. Quantities scale linearly; heat and timing don't.
New chocolate amount
100 g × 2.5 = 250 g. Apply the same factor to every ingredient.
Some recipes don't scale cleanly. Cooking times, oven temps, and salt ratios sometimes need real-world adjustment.
