When you're yearning for spring or want to cool off on a hot June day, the Cake Therapist has just the dessert. In the novel, my pastry chef character Neely features blueberry and lemon as signature flavors for March. She knows we're all yearning for warm weather after the bluster and cold of winter.
But here it is June. It's 95 degrees in the shade in Kansas City. Blueberry season.
And I want a fresh-tasting lemon and blueberry cake roll with summery seersucker stripes.
I have made my fair share of cake rolls over the years. Some very time consuming, some that stuck to the pan, some that wouldn't roll up. For a supposedly easy cake, there were issues.
Until I found this one.
This recipe is the essence of cake therapy, of baking happy.
You start out with a template recipe that really works.
You choose flavors that convey easy-going, fresh, summer--fresh lemon and blueberry.
You add color and whimsy (check out those seersucker stripes!).
And then you invite people over or take the cake roll to a meeting for others to enjoy.
This cake roll is also easy to make, in stages, and to roll up. The cake itself (based on the Japanese Deco Roll cake) is very supple, but the trick is to following the timing exactly—7 minutes in the oven, 5 minutes to cool before spreading on the filling and rolling this up.
Make this a polka dot cake, if you like, by piping dots instead of stripes. The only tricky part of this recipe is that the whole baking sheet needs to go in your freezer for the stripes to set for 30 minutes.
Here is a fun video from blogger Raiza Costa on how to make the cake roll (she did a Valentine's Day version, but the process is the same).
I have adapted it for Bake Happy, and you'll be happy to make it, show it off, and, even better, taste it!
Seersucker Lemon Blueberry Cake Roll
During the holidays, some bakers like to make a pumpkin cake roll or the fancier bûche de Noël, or Yule log cake roll. But there is a lot to be said for a summery version, too, in stripes of pale yellow and deeper blue. With a blueberry-studded lemon-scented filling, this cake has the look and taste of summer. Adapted from a recipe idea from Raiza Costa, who blogs at Dulce Delight.
Makes 1 cake roll to serve 8
Lemon Blueberry Filling:
1 (8-ounce/226 g) package cream cheese, at room temperature
3 tablespoons unsalted butter, at room temperature
1 cup (120 g) confectioners’ sugar
2 teaspoons freshly grated lemon zest
1 1/2 cups/300 g fresh or frozen blueberries
Confectioners’ sugar, for dusting
2 large egg whites
2 tablespoons granulated sugar
2 tablespoons unsalted butter, at room temperature
2/3 cup (75 g) unbleached all-purpose flour, or more, if necessary
Blue and black gel food coloring
Lemon Cake Roll:
4 large egg whites
1 teaspoon cream of tartar
1/2 cup plus 1 tablespoon (112 g) granulated sugar, divided
4 large egg yolks
5 tablespoons (45 g) unsalted butter, melted
3/4 cup (85 g) unbleached all-purpose flour
Mint sprigs, for garnish
Line a 17 by 11-inch baking sheet with parchment paper; set aside.
For the Lemon Blueberry Filling, place the cream cheese, butter, confectioners’ sugar, and lemon zest in a food processor and process until smooth and creamy. Set aside.
Arrange a piece of parchment paper on a flat work surface and dust with confectioner’s sugar.
For the Blueberry Stripes, whisk the egg whites, sugar, butter, and flour together until smooth and thick. Color with gel food coloring until you get a dark blue. Put the mixture in a squirt bottle with a 1/8 to 1/4-inch opening at the tip. Squirt squiggly blueberry stripes, about 1 inch apart, across the short side and down the length of the prepared baking sheet. Transfer the baking sheet to the freezer and let the stripes set for 30 minutes.
When ready to bake, preheat the oven to 400°F (200°C). Beat the egg whites with the cream of tartar until foamy in a large bowl with an electric mixer. Beat on medium speed until soft peaks form. Then add half of the sugar (5 tablespoons/75 ml), 1 tablespoon at a time, beating on high speed, until white, billowy peaks form. Set aside.
In a medium mixing bowl, whisk the egg yolks, with the remaining 4 tablespoons sugar, melted butter, and flour together until smooth. Add half of the beaten egg whites and fold them in with a spatula or large metal spoon until the color is uniform. Add the rest of the beaten egg whites and fold until the color is uniform.
Remove the baking sheet with the blueberry stripes from the freezer. Spoon the cake batter over the stripes in a thin layer. Smooth the batter with an offset spatula or flour scraper. Using your forefinger, make a clean channel along the perimeter of the cake batter so that the batter does not touch the sides of the pan.
Bake for 7 minutes or until the cake feels firm when you press it in the middle and the edges are just starting to turn golden.
Immediately invert the cake onto the confectioner’s sugar-dusted parchment paper. Peel off the parchment paper from the top of the cake and discard. Place a new sheet of parchment paper over the cake. Holding the cake at both ends, carefully and quickly turn the cake over again and peel off the parchment so that the confectioner’s sugar-dusted side is up. Let cool for 5 minutes.
Spread the cake with the filling and sprinkle with blueberries. Starting with a short side, carefully and firmly roll up the cake.
To serve, transfer the cake to a platter and serve with a scattering a blueberries and fresh mint sprigs. If necessary, trim the ends a little bit with a serrated or cake knife to make a more attractive cake roll.
