Jam and Cream Sponge Cake Roll with Blueberry
A classic sponge cake roll features a light, airy sponge layer baked thin and rolled while still warm, then filled with whipped vegetable cream and blueberry jam. The combination of fluffy cake, tart jam, and sweet cream creates layers of texture and flavor that balance perfectly. This dessert suits anyone seeking an elegant yet approachable showstopper for afternoon tea, dinner parties, or celebrations. The version here emphasizes gentle handling throughout to keep the sponge tender and prevent cracking, using a damp towel method that locks in moisture as it cools. Unlike dense butter cakes, this roll relies on whipped egg whites for lift, making it lighter and less rich while still delivering impressive visual impact when sliced to reveal the colorful jam and cream swirl.

Tips
Roll the warm cake while still in the towel to set its shape and prevent cracking once cooled. This step locks moisture into the sponge, keeping it tender rather than dry and brittle.
Use an electric whisk to beat egg whites until they hold firm peaks before folding in yolks. Properly aerated whites provide the lift that gives this cake its signature light, airy crumb.
Chill the assembled roll for at least one hour before serving. This firms the cream and jam layers, making the roll easier to slice cleanly and preventing filling from squishing out.
Good to Know
Cover tightly and refrigerate for up to 3 days. Do not freeze as the mousse-like cream filling separates when thawed.
Bake the sponge cake layer one day ahead, wrap it in plastic, and store at room temperature. Assemble and fill no more than 8 hours before serving.
Serve chilled or at cool room temperature. Accompany with fresh whipped cream, additional jam, or fresh berries if desired.
Common Mistakes
Fold dry ingredients too vigorously to avoid deflating the whipped egg whites and producing a dense, flat cake.
Roll the cake while it cools to avoid cracks and brittleness that develop if the sponge is allowed to cool flat first.

FAQ
Can I substitute dairy cream for vegetable cream?
Yes, heavy whipping cream works as a direct 1:1 substitute. Whip to firm peaks. Regular dairy cream may require slightly more whipping time to reach the same consistency as plant-based versions.
What if the sponge cake cracks when I roll it?
If cracks form, roll gently and use the jam and cream filling to help bind the pieces together. Cover the seams with jam and cream. Once chilled, the roll stabilizes and minor cracks become unnoticeable. Prevent cracks by rolling while warm and using a damp towel.
How long can the assembled cake roll be stored?
Refrigerate the finished roll for up to 3 days covered tightly. Do not freeze because the whipped cream filling separates and becomes grainy when thawed. Serve while fully chilled for best slicing and texture.
