Oatmeal lactation cookies are so yummy it is ridiculous. I live on pinterest looking for inspo and ideas to keep my milk supply boosted as much as possible.
That’s why I created these…

Delicious oatmeal lactation cookies with cinnamon accents that mask the brewer’s yeast so well, you don’t even know it’s there.
Brewers Yeast is quite the ingredient, let me tell you! Its appearance is not appealing at all and smells and looks like unflavored protein powder. It is best to be used in drinks or baking to hide its flavor.
Now you are probably wondering, “What does it taste like?”. Well, it has a nutty taste to it, it pretty much tastes like slightly bitter unsalted nuts. The flavor is not that bad depending on how you use it.
I actually managed to create this decadent Lactation Brownie recipe that compliments brewers yeast pretty well.
These cookies are super low-calorie and make a GREAT breastfeeding snack or breakfast snack! Hide them once you make them before everyone finds them and devours them!
Well, that might be a little hard to do as the aroma of cinnamon floods your kitchen. But at least this batch makes a whopping 25-30 cookies so you’ll have plenty to share!
Using flax eggs (flaxseed meal and water), brewers yeast, and quick or rolled oats these cookies can not be any more packed with galactagogues to combat even stubborn slacker boobs!

Quick Oats work well but tend to absorb more, so that’s why I favor rolled oats for more texture! But when in a pinch quick oats are the best substitute.

Hi there!!! I love your recipe and really want to try it. But I have gluten sensitivity and I don’t bake with wheat flour. So, can I substitute it for another flour? Do you have any suggestions? Thank you.
Jasmin
Hello Damiana 🙂
Thank you for your interest in my recipe, and that is not a problem at all! Almond flour makes a great substitute at a 1:1 ratio. I haven’t tried it for this exact recipe as a replacement, but always have success using it in my others. However, ovens vary and almond flour sometimes likes to burn faster. Some have made this recipe and ended up baking for a few less minutes (using regular flour) so keep an eye on them for the last few minutes. Let me know how it works out for you! 🙂

Thank you so much! I’m about to make them now 😋 🍪🤱🏻!!
Dakota Sisk

is it better to make the dough & freeze it? or bake the cookies first, then freeze them?
Jasmin
It would be better to bake the cookies first, and then freeze them. I noticed the dough doesn’t last very long in the freezer.
Kat
Do you melt the butter or soften it?
Jasmin
Hello Kat, you soften the butter 🙂
Mallory
Can you use regular eggs?
Jasmin
Hello Mallory, yes 2 Large Eggs can be used instead. If you have a strong oven I would say leave in for about 10-12 minutes and if not done check in 3 minute intervals until your desired color is achieved 🙂

This is my second time making this recipe. I LOVE how these come out and appreciate that they aren’t loaded with sugar like some other recipes. Yummy and effective!
