6 ounces unsweetened or semi-sweet baking chocolate (I use this 73% chocolate)
3/4 cup butter (1 1/2 sticks)
1 1/2 cups granulated sugar
1/2 cup light brown sugar, packed
3 eggs
1 1/2 teaspoons vanilla extract
2 tablespoons espresso or brewed coffee, optional
1 cup all-purpose flour
1/2 c to 2/3 c Nutella

Cream Cheese Frosting
8 ounces cream cheese, softened (I used whipped)
1/2 cup butter, softened (1 stick)
1 teaspoon vanilla extract
2 to 4 1/2 cups confectioners’ (powdered) sugar (I used 4+ cups because I like very thick frosting. You could use as little as 2 cups depending on desired sweetness and thickness)
