How do I know when my mug cookie is done cooking?
When your mug cookie has finished baking the top center of the cookie may look a little wet but the edges should look more firm and set. The cookie will also be puffed up and look almost cake-like within the coffee mug. If you need more reassurance that the cookie has cooked properly, you can check the internal temperature with an instant-read thermometer. It should reach 165 degrees F.
What size coffee mug do I need?
You will want to use a standard 10 or 12-ounce size coffee mug for this recipe. Just make sure that it is microwave safe. Using a smaller cup like a Cappucino cup is a bit tricky because they are always differently sized and shaped which means that you have to do some trial and error if you wanted to try using them. The cookie could puff up over the top and make a mess, so be warned.
Is it safe to eat egg made in a microwaved cookie?
Yes, it is totally safe. The recommended temperate to cook eggs to be eaten safely is 160 degrees F. With the time this cookie in a mug is microwaved it should reach 165 degree F, so it will be perfectly safe to eat and enjoy!
