How much corn starch would you add to a Nestlé Toll House cookie recipe to make them chewy and gooey?

None. What I do is either put molasses in it or use all brown sugar instead of white and brown because it will make them chewy. It keeps them more moist, as long as you don't over cook them anyways. This is my favorite cookie recipe.

Hi

I don't know about the corn starch, but when I want chewy cookies,

I add about a tablespoon of honey and that does the trick every time.

The cookies come out soft and moist and stay that way. :)

Best solution=use all brown sugar in the recipe. Whatever amount of brown sugar is already in the recipe, use it, and then take whatever amount it says for white or granulated sugar and replace that for brown sugar.

These cookies will stay soft forever if kept in a sealed container! Also try putting in a slice of apple loosely wrapped in parchment paper and changing it daily out of the cookie container...keeps more moisture in..sometimes too much so be careful!

Corn starch is usually used as a thickener to thicken gravies, stews, etc. I don't think I've ever added corn starch to cookies.

If you want your cookies chewier, underbake them by a minute or two. If you want to keep them nice and fresh, freeze them as soon as you have taken them out of the oven and they have cooled down. When you remove them from the freezer, you can put them in the microwave oven for 15 - 30 seconds (depending on your microwave). They will be hot, chewy and fresh tasting, as if you had just baked them. I always freeze my cookies immediately after baking. It keeps them from getting that "stale" taste and texture. Of course, I always save out a few for eating first though! ;-)

If you like soft cookies use brown sugar or add molasses. That is what makes soft cookies just replace white sugar with brown or add several tablespoons of molasses to the mix.

I've never heard of using corn starch in cookies. That's a new one.

You don't add cornstarch. You just bake them for about 2 min less.

When you check on them and think oh they just need a bit more. Take them out of the oven, let them cool and finish cooking on the baking tray, then put them on a cooling rack.

If you add more flour it'll be less runny but you should cook a few runny ones first before you change the recipe.

for chewy use brown sugar, real butter, and don't cook them as long.
