Wonderful! It didn’t quite hold together, but it made a delicious “plate” for a scoop of ice cream! Next time I’ll use less sugar — a bit too sweet with chocolate chips added.

I followed this recipe exactly and it did not turn out at all. It was like oatmeal soup

Hi Alicia! Did you make any changes to the recipe?

Not to nitpick but….The first paragraph states Only 4 ingredients yet I count 7 when I read the recipe?

Hi there! Thanks for catching that! Water and salt are generally not counted as ingredients, and the vanilla extract and chocolate chips are optional. I realized I updated the post to include baking soda after publishing it the first time, as I found the recipe turned out better with it. So indeed, the recipe is five ingredients, not four. 🙂 Appreciate you bringing that to my attention! xo

I'm sorry but this did not work at all. Followed the recipe exactly and they never set.

I used almond flour, cane sugar, and olive oil cause that’s all I have and it didn’t set. I was desperate for an oatmeal cookie 😭
