9 X 12 JELLY ROLL PAN RECIPES

Steps:

• Preheat oven to 375 degrees F. Grease a jelly roll pan; line with parchment or waxed paper and grease paper.
• Stir together the flour, sugar, baking powder, and salt in a large bowl. Add the butter, 2 eggs, and the vanilla to the dry ingredients and beat with an electric mixer on high speed until fluffy. Separate the remaining 2 eggs. Place the whites in a small bowl and beat the yolks into the batter.
• With clean beaters, beat the egg whites at high speed until they are stiff; fold beaten whites into the batter just until no white streaks remain.
• Spread batter into the prepared pan and bake until the center springs back when lightly pressed, about 15 minutes.
• Sift confectioners' sugar over a linen towel that has been spread out on a work surface; invert cake onto towel. Quickly, remove parchment, trim off crisp cake edges, spread cake with jam, and roll up using towel as an aid. Tightly roll cake in towel and set aside, open side down, until completely cool, about 30 minutes. Transfer to serving plate and slice crosswise.

Steps:

• Preheat the oven to 350 degrees F. Spray a rimmed 10-by-15-inch baking sheet with cooking spray, then line with parchment paper; spray the parchment paper.
• In a medium bowl, whisk to combine the cake flour, baking powder and 1/4 teaspoon of the salt. Set aside.
• In a stand mixer fitted with the whisk attachment, whisk the egg yolks and granulated sugar until the mixture is light and forms thick ribbons when the whisk is pulled away. Whisk in the 1 teaspoon vanilla extract. With a rubber spatula, fold in the flour mixture until completely combined.
• Using a handheld mixer (or stand mixer) fitted with the whisk attachment, beat the egg whites in a large bowl until stiff peaks form, about 3 minutes on medium-high speed. Gently fold the egg whites into the batter until completely combined.
• Pour the batter onto the prepared baking sheet and spread with an offset spatula or spoon to evenly cover the parchment. Bake until the cake is springy when touched, about 10 minutes.
• Dust a clean kitchen towel with the 2 tablespoons confectioners' sugar, turn the cake out onto the towel, and roll into a log. Let cool.
• Whip the cream, 1/4 cup confectioners' sugar, and the remaining 1/4 teaspoon salt and 1/4 teaspoon vanilla into stiff peaks. Set aside for the filling and topping.
• To assemble, unroll the cake and spread the strawberry jam to cover the cake. Top with some of the whipped cream mixture, and then roll the cake into a log. Transfer to a serving plate, seam-side down, and top with the remaining whipped cream. Garnish with mint sprigs.
