Muffin style chocolate winter brownies are a must have on a cold snowy day. Light and porous chocolate batter are filled with crunchy walnuts that add texture, and smooth savory flavors. Sharp dark chocolate’s vivid color and flavor is intensified by the spicy and warming components of the cinnamon spice. ½ teaspoon of cinnamon is all that’s needed to amplify the Winter smells and tastes of these brownies. Unlike most brownies, this batter expands and needs to be baked in a mold (a muffin tin is suggested, but any mold will do).
