Crust
2 cups all-purpose flour
1/2 cup confectioners' sugar
1/4 cup (11/2 sticks) unsalted butter, cut into pieces.

Filling
3 eggs
1 can (15 ounces) solid pack pumpkin
1/2 teaspoon ground cinnamon
1/2 cup ricotta cheese
1/2 cup granulated sugar
1/2 cup dark brown sugar
2 tablespoons all-purpose flour
1/2 teaspoon baking powder
1/2 cup ground almonds
1. Preheat the oven to 350 F.
2. Prepare the crust. In a food processor, combine the flour, sugar and butter and process to make a crumbly dough. Press the mixture evenly into the bottom of a 9 x 13-inch baking pan.
3. Bake the crust in the center of the oven for 15 to 20 minutes. It should just begin to color.
4. While the crust is baking, prepare the filling. Combine the eggs, pumpkin, cinnamon, cheese, sugars, flour, and baking powder in the food processor and process until smooth. Or blend the ingredients using an electric mixer.
5. Pour the pumpkin mixture evenly over the hot baked crust. Sprinkle the almonds on top. Continue baking for 25 minutes, or until a cake tester or toothpick inserted in the center comes out clean. Let cool completely.
6. Using a sharp knife, cut into bars.
