Ok, so I saw another question answered here that said:
Natural Peanut butter is about 50% fat, butter is about 80% fat. If you want to maintain the original amount of fat in the recipe, you would decrease the butter by 60% of the amount of peanut butter you used.
I however have a recipe for oatmeal cookies that calls for 3/4 C of butter and I'd like to use a full cup of peanut butter, How do I adapt this correctly? I'm really bad at math and don't want to mess it up, haha.
Also if I'm adding that much peanut butter do I need to adjust any of the other ingredients like the flour or oats quantity?
Thanks in advance for your answers!
