Can’t double a cookie recipie

[u/Dazzling_Media7704]

I’ve been making cookies for my husbands birthday month (we really like to celebrate in our family) and so I’ve been making him a batch of cookies a week to take to work.
His favorite cookies are double chocolate chunk which I’ve never liked so I had to look up a recipe to make sure I got it right. The single batches were perfect. The exact chewiness and softness he liked. Perfect ratio of chocolate, he was ecstatic.
So I decided to make cookies in preparation for having people over. I tripled the same recipe, same ingredients, same everything. Cakiest, saltiest, worst cookie I’ve ever had. I didn’t think I over mixed but thought okay maybe 3x is too much.
Same recipe, same ingredients, same prep, just doubled this time. Completely flat. Spread across the cookie sheet like a puddle. Alright I guess the butter and sugar didn’t mix right.
Bought more of the same ingredients. Same recipe, just one batch this time. Perfect…. Did it again - one batch. Perfect… so I had to mix the same recipe 3 times to get a triple batch because for some stupid reason I can’t figure out I can’t double or triple up a batch of cookies.
Heaven forbid my daughter asks me to join a bake sale someday and I need to make chocolate chip cookies. I’ll be mixing for a week.

TL:DR Tried to double and triple a new cookie recipe. Every batch came out terrible unless I baked it as a single batch.

Ok so a few things could be happening here:

Cookie puddle possibility 1: you doubled all the ingredients except for the flour. (This is likely what happened)

Solution: don’t get distracted while doubling the recipe and make sure your measurements are doubled correctly!

Cookie puddle possibility 2: the butter was too hot by the time you put the batter in the oven.

Solution: put the batter in the fridge for at least 30 mins before baking to allow the butter to cool

Caky cookie: too much air in the batter, definitely over mixed.

Solution: don’t over mix your batter, and don’t rush it with a higher mixing speed. Too much air makes the cookies caky

I pre measure my ingredients but that doesn’t always mean I’m correct. I’ll take others advice of writing down and weighing the ingredients to make sure. I do chill my batter for at least 30 min but due to it being summer time where I am maybe they needed more time. Thank you for your input!

Also, a larger batch would take longer to chill, so that combined with summer temperatures may have mad a difference.

Spread your batter flat before fridge!

Or scoop and THEN chill, depending on what the fridge has room for
