Blotkake (Norwegian Cream Cake)

Blotkake, layered spongecake covered with drifts of whipped cream and fruit, is a dessert that Norwegians are passionate and possessive about. It is a traditional sweet finish for any festive meal, whether a long, dark winter lunch or a long, sunlit summer dinner. “Scandinavians really value lingering and feasting at the table,” said Maren Waxenberg, a Norwegian-American cook who lives in New York City and serves this cake at Thanksgiving.

Cloudberries are a protected crop in Norway and are rarely available fresh in the United States, but raspberries are a good substitute.

INGREDIENTS
FOR THE CAKE:
 Nonstick cooking spray
4 large eggs
1 cup/200 grams granulated sugar
1 teaspoon vanilla sugar or 1 teaspoon vanilla extract
1 cup/120 grams cake flour
1 teaspoon baking powder
FOR THE FILLING AND FROSTING:
3 cups/720 milliliters whipping cream
1 teaspoon vanilla extract
2 tablespoons confectioners’ sugar
3 tablespoons cloudberry, raspberry or blackberry preserves
? cup cloudberry or raspberry liqueur (such as Chambord), or berry juice of your choice
12 ounces/340 grams fresh raspberries or blackberries, for decorating (optional)

PREPARATION
Bake the cake: Heat oven to 350 degrees and mist a 9-inch springform pan with cooking spray. Combine eggs, sugar and vanilla in a large bowl and beat with an electric mixer (or the whisk attachment of a stand mixer) until light and fluffy, 3 to 4 minutes.
Sift cake flour and baking powder into a separate bowl, then fold into the egg mixture in 2 additions.
Pour batter into pan and bake on the middle rack of the oven for 25 to 30 minutes, or until a cake tester inserted into the middle comes out clean. Let cool completely before removing from pan.
Make the frosting and filling: Beat whipping cream, vanilla and confectioners’ sugar with an electric mixer until stiff peaks form. Transfer 1/3 of the whipped cream to a separate bowl and stir in preserves.
Use a serrated knife to slice cake horizontally into 3 equal layers. Arrange top layer of the cake cut-side-up on a platter. Poke a few holes in the cake layer with a toothpick, then sprinkle with 1/3 of the liqueur or juice.
Spread half the whipped cream and preserves mixture over the cake layer, then arrange middle layer on top. Poke holes in the middle layer with a toothpick and sprinkle with another 1/3 of the liqueur or juice. Top with remaining whipped cream and preserves mixture.
Arrange the bottom cake layer on top of the stack, cut-side-down. Poke more holes and sprinkle with remaining liqueur or juice. Frost top and sides of cake with the whipped cream, using a pastry bag to pipe on stars or other designs, if you'd like. Decorate with fresh berries.
