Lactation Cookies: What They Are and What to Know

Lactation cookies are cookies made with ingredients that are traditionally believed to support breast milk production. They’re often prepared with oats, flaxseed, or brewer’s yeast. For many parents, they’re simply a convenient, satisfying snack during the busy postpartum period.

Despite their name, lactation cookies are not a guaranteed way to increase milk supply. Research on the specific ingredients is limited, and people’s experiences vary. It’s helpful to think of them as food—not a substitute for feeding support or medical care.

Common Ingredients in Lactation Cookies

• Oats: A source of carbohydrates and fiber, oats are a common base for cookies and other snacks.
• Flaxseed: Ground flaxseed adds fiber and a mild, nutty flavor. It also helps bind ingredients in some recipes.
• Brewer’s yeast: This ingredient has a savory, slightly bitter taste and is often included in traditional recipes. It is different from baking yeast.
• Other additions: Chocolate chips, nuts, dried fruit, and nut or seed butters can add flavor and energy.

Do Lactation Cookies Increase Milk Supply?

There is not strong scientific evidence that lactation cookies reliably increase breast milk production. While some people feel they help, it can be difficult to tell whether a change is due to the cookies, more frequent feeding or pumping, improved rest, or other factors.

Milk production is generally influenced by how often and effectively milk is removed from the breasts. If you’re concerned about supply, a lactation consultant or health care professional can help assess feeding, pumping, and your baby’s growth. Seek prompt medical advice if your baby is unusually sleepy, has fewer wet diapers than expected, or is not gaining weight as anticipated.

Are Lactation Cookies Safe?

Cookies made with familiar food ingredients are generally treated like other baked goods, but recipes can contain common allergens such as wheat, dairy, eggs, soy, peanuts, or tree nuts. Check the ingredient list, especially if you or your baby has a known allergy or sensitivity.

Brewer’s yeast may not agree with everyone and can interact with some medications or health conditions. If a recipe includes herbs or concentrated supplements, check with a health care professional before using them while breastfeeding. “Natural” does not always mean appropriate for every person.

It’s also worth checking the sugar and calorie content. Lactation cookies can be a convenient snack, but they don’t need to be eaten in large quantities, and they aren’t a replacement for regular meals, fluids, or individualized feeding support.

Making Lactation Cookies at Home

A basic recipe usually combines oats, flour, a small amount of ground flaxseed, and optional brewer’s yeast with butter or oil, sugar, and a binder such as eggs. Chocolate chips, raisins, or chopped nuts can be added for flavor. Use a trusted recipe, and follow its instructions for ingredient amounts and baking time.

If you’d rather skip brewer’s yeast or flaxseed, you can still make a nourishing oatmeal cookie. The result may not have the traditional “lactation cookie” ingredients, but it can still be an enjoyable snack.

The Bottom Line

Lactation cookies can be a tasty, convenient treat, but they are not a proven solution for low milk supply. Enjoy them if you like them, pay attention to ingredients that may not suit you, and reach out to a qualified professional for personalized breastfeeding or pumping support.
