For serving (optional): Vanilla ice cream or whipped cream
Instructions
Make streusel topping. Preheat the oven to 375°F. In a large bowl, combine the 2/3 cup flour and 6 Tablespoons butter with a fork or pastry mixer. Then mix in the 1/2 cup oats and 1/3 cup brown sugar. Add nuts if desired.
Make pumpkin filling: Combine 1/3 cup sugar and 1 egg in a large bowl. Whisk or mix with an electric mixer for about 1 minute. Then whisk in 1/2 cup evaporated milk. Next whisk in 1 cup pumpkin, 1 teaspoon vanilla extract, 1 teaspoon pumpkin pie spice, 1/2 teaspoon cinnamon and 1/2 teaspoon salt. Pour into an 8x8" or 9x5" baking dish.
Bake. Sprinkle the streusel topping on top of the pumpkin. Then bake for 35 - 45 minutes or until the center is set. Cover the top with foil if the streusel is browning too fast.
Rest then serve warm. Remove from oven and allow to cool for 10 minutes. Then spoon into bowls. Add whipped cream or ice cream on top if desired.
Notes
Butter: If you use unsalted butter, add in 1/4 teaspoon salt with the cinnamon. Doubling: This recipe is easy to double and place in a 9x13" pan. The pumpkin mixture will be a little thicker, so you'll want to cook and additional 3-5 minutes.
