Here’s something that might be good to make for Memorial Day weekend. I think it’s a great choice for summer picnics and grilling get-togethers because it’s fun and it’s actually cool and refreshing. It helps that this cake is stuffed with whipped cream and raspberries.
I got this recipe from Martha, who got this from chef Michel Roux. The one change that I made is that I replaced the potato flour with coconut flour, mostly because I had the coconut flour. I also didn’t dust the pan with the all-purpose flour but used cocoa instead. Otherwise, everything is the same. Here’s what you need:
- 1 T. plus 1 1/2 t. butter, room temperature, for baking sheet
- 1/4 c. unsweetened cocoa, for dusting
- 3 medium egg yolks
- 1 3/4 c. confectioners’ sugar, plus more for dusting
- 4 medium egg whites
- 1/2 c. unsweetened cocoa
- 1 T. plus 1 1/2 t. coconut flour
- 1 c. heavy cream
- 1 c. raspberry coulis (see note at the end)
- 1 1/4 cups fresh raspberries
1. Preheat oven to 425 degrees. Line a rimmed baking sheet with parchment paper; butter the parchment and dust with cocoa. Set aside.
2. In the bowl of an electric mixer fitted with the whisk attachment, beat yolks and scant 1 cup confectioners’ sugar in a bowl until ribbons form; set aside. In the clean bowl of an electric mixer fitted with the whisk attachment, whisk egg whites until they reach soft peaks; add a scant 1/2 cup confectioners’ sugar and continue whisking until stiff peaks form.
3. Whisk in one-third of the yolk mixture into the egg white mixture. Fold in remaining yolk mixture using a metal spoon until it is almost fully incorporated. Sift the 1/2 c. cocoa and coconut flour into bowl. Gently fold with a metal spoon until just combined.
4. Using an offset spatula, spread batter on prepared baking sheet to form a 10 1/2-by-12-inch rectangle, about 5/8 inch thick. Transfer to oven and bake until cake springs back when touched, 8 to 10 minutes.
5. Meanwhile, line a large wire rack with a clean dish towel. Turn cake out onto prepared rack and carefully peel off parchment paper. Let stand 5 minutes to cool.
6. Now in the bowl of an electric mixer fitted with the whisk attachment, beat heavy cream with remaining 1/4 cup confectioners’ sugar until ribbons form. Set aside.
7. Carefully transfer cake to a large piece of wax paper. Using a pastry brush, brush 1/4 cup coulis over cake. Using a serrated knife, carefully trim edges from all four sides. With an offset spatula, spread whipped cream over cake, leaving a 5/8-inch border all around. Top with raspberries. Starting from one of the long sides, gently roll up cake, using the wax paper to help you. Transfer cake to refrigerator and let chill 2 to 3 hours.
8. Slice roulade crosswise and serve dusted with confectioners’ sugar and drizzled with coulis.
Notes — Whenever I make roulades / jelly rolls, sometimes (like in this case) I end up cracking them. Most of the time it doesn’t matter because you’ll be putting frosting or whipped cream or whatever on the outside. That can help cover up stuff that’s not ideal. This cracked as well, but you serve it up sliced covered with powdered sugar and raspberry sauce and it’s still fabulous. . . As for the a quick and simple Raspberry Coulis, take a cup of simple syrup, 3 cups of raspberries (I used frozen), and the juice of a lemon. Put everything in a blender and pulse until smooth. Run through a sieve to remove seeds. But you can also check what Martha had listed; there is a link to a coulis recipe on her roulade post.
