Instructions

Preheat oven

Preheat your oven to 350°F (175°C) and line a 10x15-inch jelly roll pan with parchment paper.

Pro tip: Ensure the parchment paper covers the sides to prevent sticking.

Prepare dry ingredients

In a bowl, whisk together the flour, baking powder, and salt. Set aside.

Whip egg whites

In a clean bowl, beat the egg whites until soft peaks form. Gradually add half of the sugar and continue to beat until stiff peaks form.

Pro tip: Ensure no yolk is in the whites for best volume.

Mix egg yolks and sugar

In a separate bowl, beat the egg yolks with the remaining sugar until thick and pale. Stir in the vanilla extract.

Pro tip: Beat until ribbon stage for best texture.

Combine mixtures

Gently fold the dry ingredients and ground pistachios into the egg yolk mixture. Then fold in the egg whites in thirds, being careful not to deflate the batter.

Pro tip: Use a spatula and a light hand for folding.

Bake the sponge

Spread the batter evenly in the prepared pan. Bake for 10-12 minutes or until the cake springs back when touched lightly.

Pro tip: Do not overbake to keep the sponge pliable.

Roll the cake

Turn the cake out onto a clean kitchen towel dusted with icing sugar. Remove the parchment paper and roll the cake with the towel. Let it cool completely.

Pro tip: Rolling with the towel prevents cracks.

Prepare buttercream

Beat the butter until smooth. Gradually add icing sugar and beat until fluffy. Mix in cream and vanilla until well combined.

Pro tip: Adjust icing sugar for desired consistency.

Assemble the roll

Unroll the cooled cake and spread the buttercream evenly over it. Roll the cake back up tightly without the towel.

Pro tip: Use a serrated knife for clean slices.

Garnish and serve

Trim the ends for a neat appearance. Garnish the top with chopped pistachios and serve chilled.

Pro tip: Refrigerate for at least 1 hour before serving for best results.
