Preheat the oven to 350. Grease a 9 x 9 baking dish and set aside.

In a large bowl, whisk together the flour, sugar, baking powder, baking soda, cinnamon, nutmeg, and cloves. Add the grated butter and toss to combine. Add the egg, sour cream, and pumpkin, and mix until just combined. Spread 2/3 of the batter in the prepared pan.

In a small bowl, whisk together the cream cheese, egg, vanilla, and sugar. Pour the mixture over the batter. Add the remaining dough by spoonfuls on top of the cream cheese mixture.

To make the streusel mixture, mix the flour, brown sugar, salt, and pecans in a small bowl. Cut in the butter using two knives or a pastry blender, until the streusel starts to clump together. Sprinkle the streusel over the top of the top of the batter.

Bake 40-45 minutes, or until a toothpick inserted into the center comes out clean. Let cool 10-15 minutes before serving.
