Answer :
Answer:
You will need 2 cups of butter.
Step-by-step explanation:
There are 2 ways to figure this out.
#1. If you need 4 cups of flour, then you will need 2 cups of sugar.
If you need 2 cups of sugar, then you will need 1 cup of butter.
Which means that if you double the recipe you will need 2 cups of butter.
#2. If you are doubling the recipe, then you will need 8 cups of flour.
Which means you will need 4 cups of sugar.
And you will need 2 cups of butter!
I hope this helps! :)
