    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!
