Instructions:
Preheat your oven to 350°F (175°C). Grease and flour a 9×5 inch loaf pan.
Make the streusel topping: In a small bowl, combine the flour, granulated sugar, brown sugar, and cinnamon. Cut in the cold butter using a pastry cutter or fork until the mixture resembles coarse crumbs. Set aside.
Prepare the loaf batter: In a medium bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
