# Steps:
01 - Preheat the oven to 350°F. Grease and flour a 9-inch square or round baking pan, or line it with parchment paper.
02 - Combine brown sugar, flour, cinnamon, and nutmeg in a bowl. Cut in cold cubed butter using a pastry cutter or fingertips until mixture resembles coarse crumbs. Stir in nuts if using. Set aside.
03 - In a medium bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, nutmeg, ginger, and cloves until evenly combined.
04 - In a large bowl, beat softened butter, granulated sugar, and brown sugar until light and fluffy. Add eggs one at a time, mixing well after each addition. Stir in pumpkin puree, sour cream, and vanilla extract until smooth.
05 - Fold the dry ingredients gently into the wet mixture just until combined, avoiding overmixing to maintain tenderness.
06 - Pour half of the batter into the prepared pan and spread evenly. Sprinkle half of the streusel over the batter. Add remaining batter on top and spread gently. Finish by sprinkling the remaining streusel evenly.
07 - Bake for 38 to 43 minutes, or until a toothpick inserted into the center comes out clean.
08 - Allow the cake to cool in the pan for 15 minutes, then transfer to a wire rack and cool completely.
09 - Whisk powdered sugar, maple syrup, and 1 teaspoon milk together. Add additional milk to reach desired consistency. Drizzle glaze over cooled cake before serving.
