Thick, chewy, and rich with dark chocolate, these cookies feature a powerhouse trio of oats, brewer's yeast, and flaxseed to support milk supply and provide steady energy for new parents.
Whisk together the oats, flour, brewer's yeast, flaxseed, baking powder, baking soda, cinnamon, and salt in a large bowl. Set aside.
Cream the softened butter and coconut oil together using a mixer until smooth.
Add the cane sugar and beat on medium-high for 4 minutes until pale and fluffy. Add the egg, egg yolk, and vanilla, beating for another 2 minutes.
Reduce mixer to low and slowly add the dry ingredients, mixing only until the flour streaks disappear.
Fold in the chocolate chips and any optional mix-ins (coconut, almonds, or almond butter) by hand.
Preheat oven to 350°F. Scoop dough into 1-inch rounds on a parchment-lined sheet, spaced 2 inches apart.
Bake for 10-14 minutes until bottoms are light golden brown but centers look slightly underdone. Let cool completely on the pan to set.
Notes
To freeze: Scoop raw dough into balls and freeze on a tray for 2 hours. Transfer to a zip-top bag. Bake straight from frozen, adding 1-2 extra minutes to the bake time.
