I run our church's Espresso Bar on the weekends. We like to offer delicious baked goods in addition to the beverages. I always have lemon bars, frosted sugar cookies and chocolate chip cookies because they are the most popular and sometimes offer brownies and rice krispie treats but would like to try some new items. For some reason cupcakes and muffins are not popular with this crowd but bar cookies are extremely popular. Any suggestions from the Serious Eats bakers? Thank you!
