Brownies are sinfully delightful. Interestingly enough, brownies were created by Bertha Palmer in the 19th century in the Palmer House Kitchen. Brownies made their debut at the Columbian Exposition World's Fair in 1893. A century later, brownies are still a popular treat and will probably be around for centuries to come. Drawing from this inspiration, we decided to develop a healthy microwave mug brownie that is naturally gluten-free, vegan, and keto. This decadent microwave mug brownie is just enough for one person, so you won't be tempted to finish off an entire pan of brownies. 

How Long Should Brownies Be Cooked?

If you are baking the brownies in the oven, it will take about 20-25 minutes. The brownies will still wobble slightly in the middle. However, the brownies will continue to cook once you take them out of the oven. In contrast, if you are making a mug brownie in the microwave, I recommend cooking it between 1 minute and 20 seconds to 30 seconds.   

How Do You Reheat Cold Brownies?

The quickest way to reheat cold brownies is by using the microwave. The reheating time will depend on how complex the brownies are and how warm you want them to be. Place the brownie onto a microwave-safe plate and heat it in the microwave in 20-30 second bursts, gently pressing the brownie in between each shot to test for softness and temperature. Once the brownie is to your desired level of warmth, enjoy!    Alternatively, you can also reheat the brownie in the oven. This is the best option if you are trying to recreate that freshly baked brownie texture or reheating an entire pan of uncut brownies. To reheat the brownies in the oven, preheat the oven to 350 °F. Line a baking sheet with parchment paper to prevent the brownies from sticking, and place the brownies onto the pan. Heat the brownies in the oven for 10-15 minutes until they are warm.   

How Do You Know If Brownies Are Undercooked?

The crumbs will tell you whether or not your brownies are undercooked. Uncooked brownie batter has a glossy sheen. On the other hand, cooked brownies will have a duller color. If the crumbs look polished, the brownies are not finished cooking, but if the crumbs have dark, matte paint!
