Time

45 min + chill

This rolled cake stays soft and rolls beautifully without cracking. Filled with raspberry jam and mascarpone whipped cream — tastes bakery-made but is surprisingly simple.

Instructions

Sponge

1
Preheat oven to 350°F (175°C). Line a jelly roll pan with parchment and lightly grease.
2
Beat whole eggs and sugar for 5–7 minutes until pale, thick, and tripled in volume.
3
Add vanilla extract.
4
Whisk flour, baking powder, and salt in another bowl, then gently fold into the egg mixture.
5
Spread batter evenly into the prepared pan.
6
Bake 10–12 minutes, until lightly golden and springy.
7
Dust lightly with powdered sugar while warm, flip onto parchment or a towel, and roll immediately while warm. Let cool rolled up.

Raspberry Jam (if homemade)

1
Add raspberries, sugar, lemon juice, and cornstarch to a bowl over simmering water (double boiler).
2
Stir until raspberries soften and break down.
3
Cook until slightly thickened like jam. Cool completely before using.

Mascarpone Cream

1
Chill bowl and beaters 15–30 minutes before whipping.
2
Whip heavy cream, powdered sugar, vanilla, and optional salt until fluffy.
3
Add mascarpone last and mix only until smooth. Do not overmix.

Assemble

1
Optional: lightly brush cooled sponge with milk, condensed milk, or evaporated milk for an extra-moist roll.
2
Carefully unroll the cooled sponge.
3
Spread mascarpone cream evenly, then add raspberry jam.
4
Roll tightly and chill before decorating.
5
Decorate with whipped cream and fresh raspberries if desired.

Toti’s Tips

✓Whip the whole eggs and sugar for the full 5 to 7 minutes, until pale and tripled in volume. This sponge relies on that whipped air for its rise, so cutting the time short leaves a flatter, denser cake that's more prone to cracking when rolled.
✓Roll the cake up while it's still warm, right after dusting with powdered sugar. Warm sponge is flexible and bends without cracking, while a cooled sponge has set into a stiffer shape that tends to split when forced into a roll.
✓Let the raspberry filling cool completely before spreading it on the sponge. Warm filling can soften the cake too much as you spread it, making it harder to roll evenly.
✓Chill the mixing bowl and beaters for 15 to 30 minutes before whipping the cream. Cold equipment keeps the cream cold as you whip, which helps it hold stiff peaks rather than turning soupy.
✓Add the mascarpone last and mix only until smooth. Mascarpone is delicate and can break down into a grainy, loose texture if it's beaten too long or too hard.
✓Store-bought raspberry jam is a perfectly good swap if you're short on time — the homemade version just adds a fresher raspberry flavor, but either works for the roll itself.
✓This roll tastes even better the next day once it's had time to chill fully and the filling settles into the sponge.
