Preheat your oven to 350°F (175°C) and grease a 9-inch baking dish.

In a large mixing bowl, whisk together the pumpkin puree, granulated sugar, and eggs until smooth, then add vanilla, milk, and cream. Stir in spices and salt.

In another bowl, combine flour, oats, brown sugar, cinnamon, and salt. Add melted butter and mix until crumbly.

Spread the topping evenly over the pumpkin filling in the baking dish.

Bake for 40 to 45 minutes, until the top is golden brown, and the edges are firm.

Let cool for 15 minutes before serving for neat slices.
