Step 1: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan with non-stick spray or butter.
Step 2: In a medium bowl, whisk together the flour, baking soda, baking powder, salt, 2 teaspoons of cinnamon, and cloves.
Step 3: In a large bowl, combine 1/2 cup melted butter, 1 cup granulated sugar, 1/2 cup brown sugar, pumpkin puree, eggs, and vegetable oil. Whisk until smooth.
Step 4: Gradually fold the dry ingredients into the wet pumpkin mixture until just combined. Pour the batter into the prepared baking pan.
Step 5: In a small bowl, mix the 1/2 cup brown sugar, 1 tablespoon cinnamon, and 1/4 cup softened butter until a paste forms. Drop spoonfuls of this over the pumpkin batter.
Step 6: Use a knife to gently swirl the cinnamon mixture into the pumpkin batter in a zigzag pattern.
Step 7: Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool for at least 15 minutes.
Step 8: To make the glaze, beat the cream cheese, powdered sugar, milk, and vanilla until smooth. Drizzle over the warm cake before serving.
