I tried to make some delicious cookies that I found on Youtuber/blogger Tanya Burr's website. The recipe below is correct and should make you delicious cookies but I made some big mistakes.
Basically the recipe calls for 1 stick of butter and I mistook my Trader Joe's "quarters" of butter as half a stick each. Super wrong! They are each 1 stick. I double the butter in the recipe by putting two sticks in! I mean what kind of measurement is a stick anyway!! The original recipe calls for 200g but I don't have a scale because it's not the common American baking measurement system. My batter was way too wet so I added more flour to compensate but it just didn't help. The cookies were still edible, just really weirdly shaped, with super flat edges. I didn't know what went wrong until a few days later after all the cookies were gone. I ate a lot of butter. Oops!
I don't even have a photo of the final product, it was a shameful cookie. Image a brown flying saucer shaped soft cookie. It was UGLY.
Any way! Below is the original recipe, I don't trust myself to "translate" it to standard American baking measurements. One thing I often change for cookie recipes is using half brown sugar and half raw cane sugar instead of caster sugar, it's much better. I'll be trying this recipe out again soon!
