The Walter M. Lowney Company.
Well known candy and chocolate maker. Also published cook books. In his 1907 cook book, one of the first ever published recipes for brownies was included. I bet you won't find this kind of information at other Scripophily sites!
2 ounces unsweetened chocolate, coarsely chopped
½ cup unsalted butter, slightly softened
1 cup granulated sugar
½ cup bleached all-purpose white flour
¼ teaspoon salt
2 large eggs
½ cup chopped walnuts or pecans
Preheat the oven to 350 degrees. Grease an 8-inch square baking pan, or coat with nonstick spray.
In a small, heavy saucepan, melt the chocolate over lowest heat, stirring frequently until it is nearly melted. Immediately remove from the heat, stirring until completely melted. Let cool slightly.
Using a large wooden spoon and working in a medium-sized bowl, beat together the butter and sugar until they are well blended and smooth. Stir in the chocolate until it is smoothly incorporated. Stir in all the remaining ingredients until well blended.
Turn out the batter into the baking pan, smoothing to the edges. Bake on the center oven rack for 19 to 23 minutes, until a toothpick inserted in the center comes out clean.
