How much more butter should I add to my chocolate chip cookes to keep them soft?
I use a very basic recipe:
2 1/4 cups all-purpose flour
1/2 teaspoon baking soda
1 cup (2 sticks) unsalted butter, room temperature
3/4 cup granulated sugar
3/4 cup packed light-brown sugar
1 teaspoon salt
2 teaspoons pure vanilla extract
2 large eggs
2 cups (about 12 ounces) semisweet and/or milk chocolate chips
They taste REALLY good but my only issue is that they get hard in less than 24 hours no matter how quickly I put them away. I know that adding more butter can keep them softer longer but I'm not sure how much more I should add? Also would I need to add more of another ingredient?
