In order to achieve fluffy cookies, the butter MOST be room temperature. I didn’t think it was super important that the butter was room temperature so I melted it a bit in the microwave.
HUGE mistake! I had six dozen cookies turn out flat and not fluffy pretty like in the picture where I made a successful batch of cookies.
Remember to take the butter out either the night before if you’re making cookies in the morning. Or in the morning if you’re making them that night.
You’ll create cookies that are addictive and all who sample them will love you.
