A delicious breastfeeding friendly treat – Oatmeal Lactation Cookies! Made with brewer’s yeast, oats and flaxseeds to help support breast milk supply. Perfect for both new moms and seasoned ones, and a healthy snack the whole family will love. Rich in vitamins, minerals and healthy fats.


  • 3 tablespoons milled flaxseed + 1/3 cup water
  • 2 1/2 cups rolled oats
  • 2/3 cup flour (see notes)
  • 3 tablespoons brewer’s yeast
  • 3/4 teaspoon baking soda
  • 1/2 teaspoon fine sea salt
  • 1/2 teaspoon ground cinnamon
  • 1/2 cup avocado oil
  • 3/4 cup dark brown sugar
  • 1 tablespoon vanilla extract
  • 2/3 cup dairy free vegan friendly chocolate chips


  1. Make flax egg: In a small bowl, combine milled flaxseed with water. Let sit for about 5-7 minutes. Until the flaxseeds absorb the water and the consistency is gel-like. Set aside while it sits.
  2. Preheat oven to 350ºF and line cookie sheet with parchment paper; set aside.
  3. Mix dry ingredients: In a medium bowl combine oats, flour, brewer’s yeast, baking soda, salt and cinnamon; set aside.
  4. Mix wet ingredients: In a large bowl using stand mixer fitted with paddle attachment, or electric hand mixer, combine oil and brown sugar on medium-high speed until brown sugar is well mixed – about one full minute. Add in thickened flaxseed mixture and vanilla, mixing on medium-high speed until combined. 
  5. Combine: Add in bowl of dry ingredients, mixing on low-medium speed until combined. Fold in chocolate chips. Dough should be somewhat thick, kind of sticky and a little oily even.
  6. Bake: Using medium cookie scoop (about 1.5 tablespoons), scoop dough onto parchment paper and flatten to about 1/2″ thickness. These cookies don’t spread a ton, so don’t skip this step unless you want super thick cookies. Bake cookies for 7-9 minutes, making sure not to over bake. Allow cookies to cool on baking sheet for about 3 minute before transferring to wire rack to cool completely. TIP: I like to test 2-3 cookies first to see how they bake before baking an entire sheet.
