Method
Make the streusel
- Stir the oats, brown sugar, and cinnamon together in a small bowl.
- Mix in the melted butter until clumps form.
- Refrigerate the streusel while you prepare the cake.
Make the filling
- Beat the cream cheese, powdered sugar, sour cream, and lemon juice in a medium bowl until smooth.
Make the cake
- Heat the oven to 350°F.
- Grease a 9x13-inch baking dish.
- Whisk the flour, baking powder, baking soda, pumpkin pie spice, and salt together in a medium bowl.
- Whisk the granulated sugar, eggs, pumpkin puree, oil, milk, and vanilla together in a large bowl until smooth.
- Add the flour mixture to the pumpkin mixture and stir just until no dry flour remains.
Assemble and bake
- Spread half of the batter in the prepared dish.
- Spread the cream cheese filling over the batter.
- Dollop the remaining batter over the filling and gently spread it into an even layer.
- Sprinkle the streusel evenly over the top.
- Bake for 45–55 minutes, until the cake is set and a toothpick inserted into a cake portion comes out with a few moist crumbs.
- Cool in the dish for at least 1 hour before cutting and serving.
Notes
For clean slices, chill the cake before cutting. Refrigerate covered for up to 4 days; freeze individual slices for up to 2 months. For a gluten-free option, use a 1:1 gluten-free baking flour blend.
