Ingredients
Method
For the Cake
- Preheat oven to 350.
- Grease and flour a 9-by-13-inch baking pan.
- In a bowl or on sheet of wax paper, lightly whisk the flour, baking powder, baking soda, salt, cinnamon, ginger, allspice, and nutmeg.
- In a large bowl, combine the granulated and brown sugars. Add the eggs and oil and beat with an electric mixer on medium-high speed about 2 minutes (the mixture should be smooth and slightly lightened in color). At low speed, mix in the pumpkin, vanilla, and lemon zest. Mix in the flour mixture until just combined.
- Pour batter into prepared pan and smooth the top. Bake 30 to 40 minutes, until the cake begins to pull away from the sides of the pan and a tester inserted in center comes out clean. Transfer pan to a wire rack to cool completely. Store covered at room temperature until ready to serve.
For the Topping
- In a large bowl, beat the cream with an electric mixer on high speed until it holds soft peaks, 2 to 3 minutes. In a separate medium bowl, blend the mascarpone, sugar, zest, juice, and vanilla on medium speed until combined. Use a spatula to gently fold in the cream. Cover and refrigerate until serving time.
- Serve cake slices with a dollop of topping.
Notes
For a nondairy dessert, omit the topping and simply dust the cake slices with confectioners' sugar.
