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 😭

Any ideas on how to do this since I don’t own a microwave? Maybe keep the ingredients in a Pyrex measuring cup and bake in the toaster oven for 8-10 minutes? What do you think?

Hi Allison,
I'm not sure how long it would take in a toaster oven, as I've never made a mug dessert in a toaster oven :( In a regular oven, it takes 28-30 minutes at 350. Sorry I couldn't be more helpful!
