  1. These cookies were awesome. Just made a batch and perfectly soft and chewy. My hubbie likes it buttery so I increased the butter and decreased the sugar by a few tablespoons.

    1. Stop!! Don’t make these cookies without decreasing the amount of flour .. 2 cups will cause cookies not to flatten out

  2. I was interested in making these, but as a teenager, I don’t have an electric mixer. I have a hand mixer, but it’s older and I’m not sure if it can withstand cookie dough. Do you think the cookies will turn out the same if I hand mix them? In the past I have had problems. Thank you, this sounds like a great recipe:)

  3. These are the BEST chocolate chip cookies ever! I have been baking a LONG time and have always found it hard to find the perfect recipe for soft cookies. I double the recipe for the group home I work at and they disappear fast! Thank you so much!

  4. I am not based in the US… so want to try these but not sure what the English equivalent of 3/4 butter is? How many grams or lbs is that?
    Excited to try them…

  5. These are my go-to chocolate chip cookie recipe! They are ALWAYS so soft. I just made a batch and I have no idea why they turned out flat. Anyone know why this sometimes happens and what I can do about it?

    1. We’re glad your enjoying the cookies as much as we do. Not sure why they turned out flat for you the last time baking them…hmmm…

  6. Thanks so much for this post. Chocolate cookies are loved by most people I know. And most of us discovered our love for them as small children in the comfort of grandma’s kitchen. For some reason her cookies were always much better than mom’s. Maybe it is because they were always hot and soft or because she probably let you eat as many as you wanted. Whatever the reason, one thing is sure. We loved, and maybe still do love, chocolate chip cookies.

  7. I just made a batch of these and they were they were the perfect chocolate chip cookie. Thank you for sharing your secret ingredient. This will be going in my β€œfavorites” file?

  8. These look and sound so fab, but as good as those cookies look, the smile on your daughter’s face is the best! I can tell she knows what deliciousness is on the way!!

    Thanks for sharing at Fiesta Friday this week!


  9. I made these exactly as directed and I actually quadruple checked my ingredients and these did not turn out as expected. They were very dry and crumbly; more like a biscuit dough and quite bland in flavor. The were actually fluffy! Which is a positive. πŸ™‚
