5 ounces good-quality semi-sweet chocolate bar
1 cup whole wheat pastry flour or white whole wheat flour (all-purpose is a fine substitute)
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 cup old-fashioned rolled oats
1/2 cup walnuts, very, very finely chopped (by hand)
1/4 cup unsalted butter, at room temperature
1 cup dark brown sugar (light is fine too)
1/4 cup unsweetened, natural applesauce
1 large egg
1 1/2 teaspoon vanilla extract
1/4 cup large-grain sugar (fex: turbinado)
Preheat your oven to 350F degrees, racks in top and bottom third. Line a couple baking sheets with parchment paper.
Finely chop the chocolate bar into 1/8-inch pieces, more like shavings really. Try to avoid big lumps and chunks, which make flattening out the cookie dough later more difficult.
In a mixing bowl, whisk together the flour, baking powder, baking soda, salt, oats, walnuts, and shaved chocolate. Set aside.
Using a mixer beat the butter until fluffy. Beat in the sugar and mix until it is also light and fluffy. Scrape down the sides of the bowl once or twice. Beat in the applesauce, then the egg, mixing until both are well incorporated, scrape down the sides of the bowl once or twice. Beat in the vanilla. Add the flour mix and stir by hand until the ingredients barely come together into a uniform dough.
Scoop out the dough in teaspoons and roll into a ball shape. Place two inches apart on your prepared baking sheets. Gently flatten each dough ball into a thin, round patty with two fingers and then sprinkle the top of each cookie with a pinch of large-grain sugar. Bake for 7-10 minutes or until cookies are golden and fragrant. Remove from oven, and cool on a wire rack.
