Aunt Aggie’s Peanut Butter Cookies
Originally published back in our first few days online, back in 2007. Sept 26, 2007.
This recipe was my favourite cookie as a kid and one of the very first that I learned to bake.
The one thing I was totally in love with at the time were my Aunt Martha’s peanut butter cookies. We alway’s called her Aggie, which I
I would often ride my bike to her house to “visit” my cousins.
In fact, I really was looking for the multiple batches of theses cookies that always seemed to be baked every week.
I can’t venture a guess as to how many of these I ate in my formative years with a glass of ice cold milk.
The tradition continues to the next generation as my daughter Olivia makes these all on her own now and whipped up a batch after school yesterday.
Yet another arena in which she is destined to surpass my skills! 😉
Some things to remember for baking almost any sheet pan cookie recipe.
Your oven temperature and the type of cookie sheet you use will vary the baking times considerably. When they are golden brown around the edges is the time to remove them from the oven.
Thinking they are a little underdone is probably a good thing. Experiment by baking only a couple of cookies at a time to see what the perfect baking time is for your oven.
Baking a few cookies at a time and noting the baking time each time will help you get the best result from your oven. I’ve seen different ovens have as much as 2 minutes difference in the bake time.
I also highly recommend aluminum cookie sheets. In my experience the darker the metal in the pan the faster they conduct heat and are more likely to bake too quickly or burn.
In my years of experience aluminum cookie sheets covered in parchment paper are the best.

Please could you include metric amounts as well as cup measurements as cup sizes tend to vary. I live in UK & we tend to use gms/lb ozs for measuring as more reliable. Also oven temperature can vary in USA depending on altitude, not sure if it’s applicable where you’re posting from? Thanks in anticipation of new gram measurements 🤗

These sound and look delish. I like your comment about the type of pans to use: I purchased some dark aluminum pans years ago that were large, thinking that they would be perfect for cookies as I could do more per pan....wrong. Worst purchase ever. I got rid of them after burning several trusted cookies recipes. The lighter in colour the pan, the better in my opinion!
