Brownies are a classic American favorite. Rich and chocolatey, they can be melty or cakey depending on personal preference. Everyone can agree though that they are best served warm with a scoop of vanilla ice cream. These Walnut and Maple Syrup brownies have a rich warm maple flavor in addition to the decadent chocolatey flavor. Chopped walnuts add a nice crunch to each bite. Bake time for these brownies is 20 minutes.
