- 2 teaspoons Ground Cinnamon (for topping)
- 1/2 teaspoon Ground Nutmeg (for topping)
- 1/2 teaspoon Salt (for topping)
- 1 cup cold Unsalted Butter, cubed (for topping)
- 8 ounces full-fat Cream Cheese, softened (for filling)
- 1/4 cup Granulated Sugar (for filling)
- 1 Large Egg Yolk (for filling)
- 1 teaspoon Vanilla Extract (for filling)
- 2 cups All-Purpose Flour (for batter)
- 2 teaspoons Baking Powder (for batter)
- 1 teaspoon Baking Soda (for batter)
- 1 teaspoon Salt (for batter)
- 2 teaspoons Ground Cinnamon (for batter)
- 1 teaspoon Ground Ginger (for batter)
- 1/4 teaspoon Ground Cloves (for batter)
- 1/2 cup Unsalted Butter, softened (for batter)
- 1 cup Light Brown Sugar, packed (for batter)

- 2 Large Eggs (for batter)
- 1 cup Pumpkin Puree (100% pure)
- 1/2 cup Buttermilk
- 1 teaspoon Vanilla Extract (for batter)
Instructions:
- Preheat oven to 350°F (175°C). Grease and line a 9x13 inch pan with parchment paper, ensuring an overhang on two sides for easy lifting.
- Prepare the Streusel Crumb Topping: In a bowl, whisk together the flour, brown sugar, granulated sugar, cinnamon, nutmeg, and salt for the topping. Cut in the cold, cubed butter using your fingers or a pastry blender until coarse, pea-sized crumbs form. Place the topping in the refrigerator to keep it cold.
- Prepare the Cream Cheese Filling: In a small bowl, beat the softened cream cheese and sugar until smooth. Beat in the egg yolk and vanilla extract until just combined. Set aside.
- Prepare the Dry Cake Mix: Whisk together the flour, baking powder, baking soda, salt, cinnamon, ginger, and cloves for the batter in a medium bowl.
- Cream Wet Ingredients: In a large bowl, cream the softened butter with the brown sugar and granulated sugar until light and fluffy (about 3 minutes). Beat in eggs one at a time, followed by vanilla extract. Mix in the pumpkin puree until just incorporated.
- Combine Batter: Alternate adding the dry ingredient mixture and the buttermilk to the wet mixture, beginning and ending with the dry ingredients. Mix only until just combined—do not overmix!
- Assemble the Cake: Spread half of the pumpkin cake batter evenly into the prepared pan. Dollop the cream cheese filling randomly over the batter layer. Use a knife to gently swirl the filling through the batter. Spread the remaining cake batter over the top, smoothing carefully.
- Top the Cake: Generously sprinkle the chilled streusel topping evenly over the entire top layer of batter.
- Bake: Bake for 50–60 minutes, or until a toothpick inserted into the centre comes out mostly clean with only a few moist crumbs attached. The cake should feel firm to the touch.
- Cool: Cool the Pumpkin Cream Cheese Crumb Cake completely in the pan on a wire rack before slicing into 12 squares and serving.
