Recipe: Pumpkin Swirl Cake (using fresh pumpkin) (food processor)

PUMPKIN SWIRL CAKE

1 small sugar pumpkin
Soft butter for the pan
2 cups unbleached all-purpose flour
1 1/2 teaspoons baking powder
1/4 teaspoon fine sea salt
1 teaspoon ground cinnamon
1/2 teaspoon grated nutmeg
1/4 teaspoon ground cloves
15 tablespoons unsalted butter, at room temperature
1 1/2 cups granulated sugar
3 large eggs, at room temperature
1 teaspoon pure vanilla extract
1/2 cup buttermilk, at room temperature
1 teaspoon finely chopped sage, about 5 leaves (don't use dried sage)

TO COOK THE PUMPKIN:
Preheat oven to 375 degrees F. Line a large baking pan with parchment paper.

Cut the pumpkin into halves. Place the pieces on the baking pan, cut side down.

Bake in the oven until a skewer pierces them easily, about 30 minutes. Cool the pumpkin halves.

Scrape out the seeds and discard them. Scrape the flesh out of the rinds. Puree the flesh in a food processor. You will need 3/4 cup puree for this recipe. Save the rest for another use (such as soup).

TO MAKE THE CAKE:
Reduce oven temperature to 350 degrees F. Generously butter a 2-quart Bundt pan.

Sift the flour, baking powder, salt, cinnamon, nutmeg and cloves together.

Put the 15 tablespoons butter in the bowl of a heavy-duty mixer. Beat it with the paddle attachment at medium speed until it is creamy and smooth. With the mixer on low, add the sugar in a steady stream. Beat the butter and sugar on medium speed until the mixture is lighter in color and fluffy.

In a separate bowl, beat the eggs together with a fork. With the mixer running, dribble the eggs into the butter and sugar.

Add the vanilla to the buttermilk.

Alternately add the dry ingredients and the buttermilk to the mixer bowl, starting and ending with the dry ingredients. Stop and scrape down the sides of the bowl when necessary.

Stir the sage into the pumpkin puree. Add about 1 cup of the batter to the pumpkin puree and fold the 2 together. Now fold the pumpkin mixture into the rest of the batter. Fold only 2 or 3 times, leaving swirls of pumpkin in the batter. Pour the batter into the pan and smooth the top with a spatula.

Place it on the middle shelf of the oven, and bake until the top is brown and a skewer inserted into the center comes out clean, about 45 to 50 minutes.

Cool the cake. Unmold it and place it right side up on a serving plate.
