Final Answer:
To make only 1/2 of a batch of cookies, you would need 1/3 cup of powdered sugar.
Step-by-step explanation:
If the original recipe calls for 2/3 cup of powdered sugar for a full batch, making only 1/2 of the batch means you need to halve the amount. Halving 2/3 cup results in 1/3 cup, so you would need 1/3 cup of powdered sugar for half of the batch.
Understanding how to scale down or up ingredient quantities is crucial in cooking and baking, ensuring accurate and delicious results. In this case, adjusting the powdered sugar quantity maintains the proper balance of flavors and textures in the cookies.
Exploring basic principles of recipe scaling is beneficial for home cooks, providing flexibility in adjusting batch sizes and accommodating different serving needs without compromising the recipe's integrity.
