Instructions

  • Mash the banana in a 12-14 oz. microwave safe mug. Be sure to mash the banana well so no clumps remain & if you want to go the extra mile, measure the banana out so you don't use too much banana. Too much will make it overly wet or gooey.

  • Microwave for 90 seconds, check for doneness and microwave in short bursts for another 20-45 seconds or until cake is set, it will have a slightly shiny top. It’s better to under bake a mug cake, so be careful not to over cook.

Notes

  • Storage: Mug cake is best enjoyed right away. But if for some reason you do have leftovers, you can store for up to 1-2 days; just cover it with plastic wrap or transfer it to an airtight container and refrigerate.
