Having watched a great deal of The Great British Baking Show in recent months, I’m inspired to bake more creative treats. This Summertime Swiss Roll features a delicious combination of lemon almond sponge cake, lemon buttercream, and raspberry filling. I’m not sure how this cake would fare in the tent with Paul and Mary as judges, but it was absolutely delicious.
Swiss roll is another term for jelly roll; it’s a sponge-type cake with jam, preserves, buttercream, pudding, or a combination of fillings. I made a “plain” vanilla cake/strawberry preserves jelly roll earlier this summer and decided to branch out to a lemon, almond, and raspberry creation. I had some extra raspberry sauce that I served on the side of each slice; you could also garnish with fresh berries if you like.
For the cake
- 3/4 cup flour
- 3/4 teaspoon baking powder
- 1/4 teaspoon salt
- 4 eggs, at room temperature
- 3/4 cup sugar
- 3/4 teaspoon almond extract
- 1/4 teaspoon lemon extract
- 1 tablespoon lemon zest
For the filling
- 6 tablespoons unsalted butter, at room temperature
- 1/2 teaspoon lemon extract
- 1 teaspoon lemon zest*
- 1-2 teaspoons milk
- About 3/4 cup raspberry filling
*You can omit the zest if you like and use a full teaspoon of lemon extract if you prefer.
Preheat oven to 400 degrees. Line a 10 x 15 x 1 pan with parchment. Place a lint-free tea towel on a heatproof surface (I use a cutting board) near your oven and lightly dust it with powdered sugar.
In a small bowl, sift together flour, baking powder, and salt; set aside. In a mixer fitted with the whisk attachment, beat eggs until foamy, then slowly add the sugar, beating on medium speed until the mixture is thick and a light lemon color, about 5-7 minutes; add almond and lemon extracts and lemon zest just before you stop beating. When the batter is done, it will fall from the whisk in a ribbon, then mound on top of the batter before blending back in. Gently fold the flour mixture in (I used my whisk attachment for easy clean-up).
Pour batter into prepared pan, spreading with a spatula to create an even layer. Bake for 12-14 minutes, until the top is golden brown and springs back when you touch it. Remove from oven, then quickly and carefully flip your cake onto the powdered sugar-sprinkled tea towel. Gently peel the parchment away, then starting at one of the short ends, roll the cake up in a tight spiral and allow to cool on a wire rack completely before filling.
To make the buttercream, in a mixer fitted with the paddle attachment, beat butter on medium speed for about 1 minute. Add powdered sugar and beat on low speed until the sugar is fully incorporated into the butter, about 3-5 minutes. Add lemon extract, 1 teaspoon milk, and lemon zest, if using; continue to beat on medium-high speed for another 1-2 minutes. Add remaining milk if necessary.
To fill, unroll the cake and spread with buttercream, then raspberry filling; roll back up and wrap in plastic; chill for about 30 minutes to help filling set. Store, covered, in the refrigerator for up to 3 days.
