What are lactation cookies?

Lactation cookies are cookies that include ingredients commonly used to support breastfeeding. Nursing parents often benefit from nutrient-dense foods because producing breastmilk increases nutritional needs. Ingredients like oats, brewers yeast, and flaxseed meal are frequently included in lactation cookie recipes because they provide fiber, B-vitamins, and healthy fats — all in a convenient, tasty form. Keep in mind that individual responses vary, and these cookies are intended as a nourishing snack rather than a medical treatment.

Ingredients for Lactation Cookies

• 1/4 cup melted unsalted butter
• 1/2 cup light brown sugar, packed
• 2 tablespoons maple syrup
• 1 teaspoon vanilla extract
• 1 large egg
• 1/2 cup creamy all-natural peanut butter (or other all-natural nut butter)
• 2 cups quick-cooking oats (gluten-free if desired)
• 2 tablespoons flaxseed meal
• 2 tablespoons brewers yeast
• 1 teaspoon baking soda
• 1/2 teaspoon sea salt
• 1/2 cup dark chocolate chips
• Additional sea salt for sprinkling on top (optional)

Ingredient swaps and tips

Cooking at home often requires flexibility. Below are easy substitutions that work well in this recipe:

• Nut butter: Any runny, all-natural nut butter—like almond or cashew—can replace peanut butter.
• Egg: This recipe is written with one egg. If you prefer to experiment with a flax egg (1 tablespoon flaxseed meal + 3 tablespoons water), results may vary.
• Brown sugar: Coconut sugar or another granular brown-style sugar can be used in place of light brown sugar.
• Oats: Quick-cooking oats are recommended for texture, but rolled oats can also work. The cookies will be slightly heartier with rolled oats.
• Butter: Unsalted butter adds flavor and texture; other fats haven’t been tested here but you can try experimenting cautiously.

How to Make Lactation Cookies

1. Preheat and prepare

Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper or lightly spray with nonstick cooking spray.

2. Combine wet ingredients

Cream the melted butter, light brown sugar, maple syrup, and vanilla in a large mixing bowl using an electric mixer or a whisk. Add the egg and the peanut butter, mixing until smooth and well combined.

3. Add dry ingredients

Stir in the oats, flaxseed meal, brewers yeast, baking soda, and salt until evenly incorporated. Fold in the dark chocolate chips. The dough should be cohesive and slightly sticky — similar to regular cookie dough.

4. Form cookies

Scoop about 2 tablespoons of dough and roll it into a ball with slightly moistened hands if needed. Place each ball on the baking sheet and gently press down to flatten into a cookie shape. Sprinkle a pinch of sea salt on top of each cookie, if desired. Fit about six cookies per sheet, leaving space between them.

5. Bake and cool

Bake at 350°F for 11–14 minutes, or until the edges begin to turn golden brown. The centers will still be soft. Remove from the oven and allow cookies to cool on the baking sheet for a few minutes, then transfer to a wire rack to cool completely and firm up for at least 20 minutes.

Top tips

• Dough too wet? Chill the dough in the fridge for 30 minutes to firm up before scooping.
• Sticky dough: Slightly moisten your hands when rolling to prevent sticking, and wash hands occasionally between cookies.
• Flatten before baking: These cookies spread only a little while baking, so press them down slightly for a flatter, chewier cookie. If you skip this step, you’ll get a domed cookie.

Storage

Let the cookies cool completely. Store in an airtight container at room temperature for up to 5 days.

Freezer instructions

After cooling, place cookies in a freezer-safe bag or container, removing as much air as possible. Freeze for up to 3 months. Thaw at room temperature or warm gently before serving.

Pro tip: Make a double or triple batch to keep in the freezer for quick snacks or to give as a thoughtful gift to a new parent.
