The most challenging part of the jelly roll cake is the genoise. But once prepared, it takes a mere 7 minutes to bake in the oven. After that, you just let it cool and fill it with your favorite jelly or cream or both.
This Martha Stewart recipe (August 2012 issue) is beautiful and delicious…
- Prep Time 25 minutes
- Total Time 3 hours
- Yield Makes one 10-inch roll
For the Genoise
- Vegetable-oil cooking spray
- 1/2 cup plus 1 tablespoon cake flour (not self-rising), plus more for pan
- 1/3 cup skinned whole hazelnuts, deeply toasted
- 1/4 teaspoon salt
- 3 large eggs plus 2 large egg yolks
- 1/2 cup granulated sugar
- 1/2 stick unsalted butter, melted but not very hot
- 3 to 4 tablespoons confectioners’ sugar for dusting, plus more for towel
For the Filling
- 1 cup plus 3 tablespoons high-quality raspberry preserves or jam, such as Bonne Maman (one 13-ounce jar)
- 1 cup very cold heavy cream
- 2 tablespoons hazelnut liqueur, such as Frangelico
- Make the cake: Preheat oven to 400 degrees. Coat an 11 1/2-by-17-inch rimmed baking sheet (1/2 inch deep) with cooking spray, and line with parchment. Coat parchment with spray, and dust with flour, tapping out excess. Bring a pot of water to a simmer. Meanwhile, pulse hazelnuts, flour, and salt in a food processor until nuts are finely chopped, about 1 minute. Sift flour mixture, discarding any pieces of nuts in sieve.
- Whisk together eggs, yolks, and granulated sugar in a heatproof bowl set over a saucepan of simmering water, until sugar dissolves and mixture is warm, about 2 minutes. Remove from heat. Beat with a mixer on medium speed 2 minutes. Raise speed to high, and beat until pale and fluffy, about 4 minutes. Sprinkle flour mixture on egg mixture in 3 additions, folding with a rubber spatula and drizzling in butter toward end of last addition. Spread batter in pan, and bake until top is golden, 7 to 8 minutes.
- Loosen cake from pan with a paring knife. Dust a clean kitchen towel with confectioners’ sugar, and invert cake onto towel. Peel off parchment. Starting from a short side, tightly roll up cake in towel. Let cool completely, about 1 1/2 hours.
- Make the filling: Unroll cake, and spread with jam, leaving a 1/4-inch border on all sides. Beat cream with liqueur until medium peaks form. Spread cream over jam, leaving a 1-inch border on all sides. Starting from a short side, roll up cake as tightly as possible. Place cake, seam side down, on a baking sheet or in a platter. Refrigerate at least 1 hour and up to 4 hours. Dust with confectioners’ sugar, slice, and serve.
