Many breastfeeding women find that oatmeal helps increase their milk supply, and one great (and delicious!) way to eat oatmeal is overnight oats. These lactation overnight oats with peanut butter and chocolate chips have brewer’s yeast and flax seed in addition to oatmeal to turbo charge their milk making power.

When I was exclusively pumping, I did an experiment to see whether eating oatmeal would affect my supply. The result was that it did! On the days when I ate oatmeal for breakfast, I pumped about an ounce or two more than on the days I didn’t.

However, I really do not care for oatmeal – at least not oatmeal made the way I was making it, which was pouring old fashioned oats and water in a bowl, microwaving them for a minute and a half, and stirring in some Splenda. It was gross, and I basically had to choke it down every day.

However! There are better ways to eat oatmeal. One way that is really easy and delicious is overnight oats, where you mix everything together the night before, and then it’s all ready to go in the morning.

Note: This recipe will work best with all three galactagogues, but if you don’t have brewer’s yeast or flax seed on hand, you can try it without and see if just the oatmeal boosts your milk supply. The easiest way to get brewer’s yeast is on amazon.

Feel free to try other chocolate toppings in addition to or instead of the chocolate chips! I used M&Ms once when I ran out of chocolate chips and those were great, too!

  • 1/3 cup rolled oats
  • 1/3 cup milk
  • 1 tbsp peanut butter softened
  • 1/2 tsp vanilla
  • 1 tsp honey
  • 1 tsp brewer's yeast
  • 1 tsp flaxseed
  • 2 tbsp chocolate chips


  • Put all ingredients into a bowl and stir until well mixed
  • Cover and place in the refrigerator overnight (or for at least 5 hours)
  • Sprinkle chocolate chips onto the top of the oatmeal and enjoy!


The peanut butter is easier to stir into everything else if it's softened. To avoid using another bowl, I put the peanut butter in first and microwaved for 20 seconds or so and then added everything else.
When you're ready to eat, stir in a little more milk if you'd like (depending on the consistency that you prefer).
