Spiced Brownie Loaf from Mix

Prepare ingredients according to brownie box directions for eggs, oil, and water. In a large bowl, whisk together the eggs, oil, water, plain yogurt, milk, and vanilla extract until smooth. Add the brownie mix, all-purpose flour, baking powder, and ground nutmeg to the wet ingredients. Stir just until no dry streaks remain; the batter should be thick but spreadable. Pour the batter into a loaf pan. Bake at 350°F for 45-50 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
