peanut butter lactation cookies cover

Easy peanut butter cookies that are way more than just lactation cookies. Seriously, these nutty cookies are vegan, flourless, easily gluten-free, contain oatmeal, and do not forget soft and chewy!

Quarantined in Southern California means I have even more time to do what I love. Which is…

Bake until I can’t no more! I love to bake and play around with ingredients I have an abundance of in my pantry so they don’t go to waste.

Oddly enough, while organizing my pantry, I realized I have a couple of jars of peanut butter that were approaching the “best by date” and Nalani was just put down for a nap.

These cookies are not where I am stopping at. I still have more peanut butter! Which means what to create next? Keep an eye out, my next creation will be out within the next couple days! 😉

What makes these cookies different?

With time on my side, I played around and using my lactation aides (brewers yeast, old fashioned oats, and flaxseed meal) I made some delicious, soft, and chewy peanut butter lactation cookies! 🙂

Just like my Cinnamon Oatmeal Lactation Cookies recipe, flax egg is called for meaning no eggs needed, therefore making it vegan! No flour is needed either, and I found adding the oats really helped provide structure. Substituting Gluten-Free Oats instead will instantly give you a Gluten-Free version making this recipe even more of a keeper!

These cookies make the perfect breastfeeding snack because of their usage of popular galactogouges like old fashioned oats, brewers yeast, and flaxseed.

I can not tell you how many unpalatable recipes I have come across with brewers yeast. Its taste is very distinctive and I always hide it as best as possible without sacrificing the typical serving size (2 Tbsp).

It is hidden very well in all of my lactation recipes. Seriously, ask my other half. He can’t stop eating them himself!

Did I mention these cookies only take 10 minutes to bake, and this recipe yields about 2 dozen (24 cookies) so you have plenty to snack on. Well, I mean to boost milk supply, but you get the point.

What are you waiting for? No time? Pin it for later, you won’t regret it!

No flour leaves these cookies tender once done baking, so be careful when transferring to a cooling rack. One completely cooled these cookies will be perfectly stable, soft, and chewy. 🙂
