Lactation smoothies, cookies, and bars are what I have commonly come across when looking at other recipes to try out. So I decided to take it one creative, yet simple step further by crafting and cutting these buttery oatmeal chocolate chip lactation cookie bars into TRIANGLES!

Enjoy them as you like, but this triangle dessert definitely just hits differently and especially once I completed it with a scoop of yummy mint chocolate chip ice cream on top. Talk about the perfect late-night breastfeeding snack.

Seriously, these are probably right at the top of my favorites right next to my Cinnamon Oatmeal Lactation Cookies recipe. Just take a look at how thick and chocolatey they are. And yes, they are chewy and perfect.

Flash empasizes how delicious these look

I am living for these lately. Nalani is almost 1, she’s going through a growth spurt now and I need all the help I can get. I’m so excited, it’s going to be Girl Boss Baby themed! She can not get enough of that show, and let’s be honest, neither can I. I may do a couple of articles on the dessert table, etc.

But seriously, these Oatmeal Chocolate Chip Lactation Cookie Triangles are amazing. They have these nostalgic taste that tastes like a Quaker Chocolate Chip Granola Bar, but thicker, buttery vanilla cookie dough, and the galactagogues that make these lactation triangles!

Top them with your favorite ice cream after they have cooled down slightly (for a cleaner cut), and enjoy! 🙂


  • Use a toothpick to check for doneness, if it comes out clean but with some melted chocolate (it’s from the chips) it’s done
  • Butter pan generously to prevent it from sticking, and to get that beautiful brown crust
  • Allow them to cool completely for clean and smooth bakery/restaurant style cuts
  • Don’t forget to top with chocolate chips before putting in the oven!!!
