Peanut Butter Oatmeal Cookies

in Cookies, Desserts

Today we’re gonna learn how to make things you probably thought could only come from a store. The first is peanut butter. Peanut butter is delicious. Peanut butter: don’t ever change. Cause you’re amazing just the way you are. Next we’re going to take this peanut butter and make peanut butter oatmeal cookies, made popular first  by the Girl Scouts as a Do-Si-Do. See, we’ve already taken on Thin Mints, so it’s time to branch out a bit.

Let’s talk peanut butter. Specifically, let’s discuss how easy it is to make. Here’s the recipe in its entirety: you take peanuts, and put them in a food processor. Then you blend them until they become smooth and creamy. The End. I personally prefer to use honey roasted peanuts, cause nothing about “honey roasted” sounds like a bad idea to me.

I wish I could tell you that these cookies are just as easy to make as peanut butter, but it’s sort of hard to compare to a recipe that is one step. However, they’re still pretty simple. I actually think that real live Girl Scouts would have an easy time making these themselves. If a Girl Scout tried to sell me cookies she had made herself, I would buy twice as many boxes, just on principle. Unless she had dirty fingernails. It’s hard to eat food that’s been handed to you by dirty fingernails. One time I was served ice cream by a kid who’s fingernails were almost black from the dirt under them. Super gross.

Here’s your agenda for the day: Make peanut butter. Then make cookies. Wash your hands first.

You’re shaming me as I realise how easy it is to make peanut butter and yet, it’s never really crossed my mind. Until now! Inspiration! These are my husband’s favourite girl scout cookie and that is reason enough. Thanks!

Mmm homemade peanut butter is the best! If don’t have a food processor and are lucky enough to be near a grocery store with a peanut butter grinder (whole foods usually has them) that is another great option!


Caroline March 15, 2011 at 4:34 pm

Whole Foods is actually where I got the idea to use the honey roasted peanuts. I love that place!


Jacqueline Gottke October 19, 2012 at 5:50 pm

YES….I put roasted unsalted almonds in the food proc. and wa-lah hellllo almond butter on toast and everything else (especially a spoon:) I work in the bakery at whole foods and it is amazing!!!

These look wonderful and anything with the words Girl Scouts + Thin Mints + Peanut Butter + Cookies…any of those words get me really excited :)


Rachel March 9, 2011 at 4:38 pm

I love anything with peanut butter, so I am trying these soon!


Joanne March 9, 2011 at 4:46 pm

I think you’d make a really good teacher. You have a lot to share with the nation’s future generations. How to make PB. How to wash your hands. How to make beautiful cookies. The important things in life.


Caroline March 9, 2011 at 4:50 pm

LOL! thanks joanne :)


Sarah March 9, 2011 at 4:56 pm

Those look amazing! I don’t have a food processor but my local grocery store sells peanut butter that is just peanuts. Yum!


laura @ alittlebarefoot March 9, 2011 at 5:26 pm

YES!! want. now.


Leigh@sweetlittlebytes March 9, 2011 at 8:23 pm

These look AMAZING! Do-Si-Do’s are my boyfriend’s favorite Girl Scout cookies, so I’m sure I’ll be making these in the near future. I’ve never tried making my own peanut butter. When I do, I’m definitely going with honey-roasted peanuts! Thanks for sharing! <3


Katrina March 10, 2011 at 4:08 am

I LOVE the peanut butter filling in these! Yum!

YUM, these look very good. I think a srinkle of raw sugar on top for crunch and they would be perfect. I cannot wait to try making my own peanut butter.


Maya March 10, 2011 at 8:52 am

I find myself drooling over your site a bit too often! These have the same affect.


Betty @ scrambled hen fruit March 10, 2011 at 6:57 pm

Making these with homemade peanut butter (with honey roasted peanuts, no less!) takes these peanut butter sandwich cookies to a whole new level. Oh my, they are wonderful!


Darcie March 13, 2011 at 7:07 pm

This looks delicious. I am definitely trying this soon. I would think this is healthier than using regular peanut butter.


Kelli @ The Corner Kitchen March 15, 2011 at 6:37 am

You can never go wrong with the peanut butter and oatmeal duo! These look amazing!


Amy @ A Little Nosh March 22, 2011 at 6:03 am

I always thought you needed to add oil to the processed peanuts. Guess not! Looking forward to making these. I may spread some melted chocolate in the middle too. Just because.


Jacqueline Gottke October 19, 2012 at 5:51 pm

NO as long as they are roasted it only takes a few minutes


snooky doodle April 13, 2011 at 1:27 pm

these look yummy :)


Leslie April 28, 2011 at 7:58 pm

Wow, I love pretty much everything on your blog…especially these sweet little cookies!! (I have to make them soon!) The homemade peanut butter is a great idea to take them over-the-top!

Thanks for sharing, and I’ll be back to see what other good ideas you have.

Just made these! They came out great! YUMMM!!! Thanks :o)


Jacqueline Gottke October 20, 2012 at 9:52 am

used almond butter….turned out fab….wonder if you made some sort of rasp or strawberry jam in place of the peanut butter in the filling if they would be superb?
