Feb 23, 2022 (Last updated May 24, 2026) by Hannah Sunderani

Hiya friends! I am back with another lactation recipe for you! Say hello to these sweet and delicious lactation brownies. Made with oats, flaxseeds and brewers yeast to help support breastfeeding mamas. They are moist, fudgy and oh-so-chocolaty. After multiple rounds of recipe testing I’m so pleased with how this lactation brownies recipe turned out.

I will preface this post by saying that I am not a nutritionist, and so you might like to speak with your nutritionist to see if this recipe is a good fit for you. I found this recipe to be incredibly helpful and sustaining during my post partum, especially in the early days, which is why I want to share the recipe with you. I cooked these on repeat in the 2+ years that I breastfed both my boys.

So, let me tell you exactly how to make these vegan lactation brownies, so you can enjoy them and all the benefits of increased milk supply!

After my lactation cookies were such a hit, I wanted to make another recipe that you could count on during the early days of breastfeeding. This is a great sweet treat to switch it up from my cookie recipe.

And I promise, it’s so easy to make these lactation brownies. I know first hand just how precious your free time is when you’ve got a baby.

Rest assured these brownies come together effortlessly, and I encourage you to send them to friends and family members to make for you.

This recipe is also perfect for preparing in advance while you’re still pregnant, and freezing for easy snacks when your little one arrives. If you’re still pregnant you’ll find my Pregnancy Must Haves helpful.

The Ingredients:

While I have an interest in nutrition, I’m not a nutritionist I’ve included where I’ve gotten my information below and why I used these ingredients in my cookie recipe. My expertise lies in making amazing tasting recipes with simple wholesome ingredients, so that’s why I created this cookie recipe.

• Oats: According to Today’s Parent: oats have a higher concentration of dietary beta-glucan than any other food. Beta-glucan  is a type of fiber that’s said to raise the levels of the breastfeeding hormone prolactin, and higher prolactin levels can have a positive effect on breast milk production. See this article about oats from Very Well Family for more about the nutritional benefits of oats and breastfeeding.
• Flaxseeds: According to The Bump, flaxseeds are among the best ways to increase milk supply thanks to their healthy fats content. I’ve used ground flaxseeds in this recipe, which is easy to digest and also helps to bind the brownies together without the use of eggs – keeping them vegan.
• Brewer’s Yeast: Of the ingredients in this cookie recipe, this is likely the most unfamiliar. Brewer’s yeast is typically sold in powdered form (or as a supplement), and its most often used to make beer and wine. I bought mine on Amazon. Brewer’s Yeast is said to be effective at increasing milk supply, and is often a main ingredient promoted in store-bought lactation brownies. This is because it’s packed with iron, protein and B vitamins, which increase milk production. Brewers yeast tends to have a bitter flavour, so I ordered the “reduced bitterness”version. It worked really well in this cookie recipe – they don’t taste bitter at all!

How to make lactation brownies

First, combine all the wet ingredients together in a medium-size mixing bowl and the dry ingredients together in a small mixing bowl. Then fold the dry ingredients into the wet to combine.

(I always like to add my dry ingredient to wet vs. the other way around to avoid any dry and clumpy bits at the bottom – little helpful tip for ya!).

Then, transfer the brownie batter to a 9×9-inch baking pan and sprinkle with chocolate chips. Bake at 350F for 25 minutes.

Let cool and then cut into squares and enjoy!

Note: Since these brownies are made primarily with oat flour, they are more fragile than traditional brownies – especially when warm!

For best taste/texture it’s important to let the brownies cool completely before cutting. They’re also delicious when enjoyed chilled from the fridge, which in turn helps with crumbliness.

So there we have it. A delicious recipe for Lactation Brownies to help breastfeeding mamas! They are made with wholesome and nourishing ingredients that you can feel good about putting in your body. Best of all, they’re so easy to make!

Prepare in advance and batch-freeze for when your little one comes along. Or, share with your partner, friends and family to make this recipe for you. I know you’re going to love snacking on these, and I hope they work as well for you as they have for me.
