Muffins and rice krispy treats are both great ideas! Yep, we will probably be sanitizing everything, wearing gloves and masks while baking, repeatedly washing hands, changing gloves between each batch/item, etc.Smores brownies are delicious!!! Though these brownies sound good (https://www.delish.com/cooking/recipe-ideas/a26363572/trash-brownies-recipe/)
Maybe try some muffins (banana, blueberry, or chocolate chip?)
or maybe rice krispy treats?
Make sure to wear masks and gloves and wash your hands and your surface!
