Special Note: Unlike our other lessons, this lesson is primarily theoretical. 


While this brownie recipe is simple, it requires 30+ minutes to bake, even with smaller batches. We are currently experimenting with more classroom friendly options.


We have provided the brownie recipe for students to do at home, as well as a highly accessible and significantly quicker “brownie in a mug” recipe that students can measure in class and then take home to finish in the microwave (it takes one minute in the microwave!).
