Ingredients:
- 1 (15-ounce) can pure pumpkin purée
- 1 (12-ounce) can evaporated milk
- 2 large eggs, lightly whisked
- 1 cup granulated white sugar
- 2 teaspoons pumpkin pie spice blend
- 1/2 teaspoon fine sea salt
- 1 teaspoon vanilla extract
- 1 box (15.25 ounces) yellow or spice cake mix (dry mix only)
- 1/2 cup packed light brown sugar
- 1 cup (2 sticks) unsalted butter, chilled and sliced into 1/2-inch pats
Instructions:
- Preheat oven to 350°F (175°C). Lightly grease a 9x13 inch baking dish.
- In a large mixing bowl, whisk together the pumpkin purée, evaporated milk, whisked eggs, white sugar, pumpkin pie spice, salt, and vanilla extract until completely smooth.
- Pour the entire pumpkin mixture evenly into the bottom of the prepared baking dish.
- Evenly sprinkle the dry cake mix over the pumpkin layer. Do not stir.
- Arrange the chilled butter pats evenly over the dry cake mix layer.
- Sprinkle the light brown sugar evenly over the butter pats and the dry cake mix.
- Bake for 50 to 60 minutes. The top should be deeply golden brown, and the edges of the pumpkin layer should look set.
- Allow the cake to cool on a wire rack for at least 30 minutes before serving to allow the gooey centre to firm up.
