To make the jam roll, start by preparing the sponge cake. In a large mixing bowl, whisk together 4 eggs and 1 cup of sugar until pale and fluffy. Add in 1 cup of flour and 1 tsp of baking powder, mixing until just combined. Pour the batter into a greased and lined baking sheet, spreading it out evenly.
Bake the sponge cake in a preheated oven at 375°F for 12-15 minutes, or until the top is firm and golden brown. Remove the cake from the oven and immediately turn it out onto a clean, damp tea towel. Carefully roll the cake up into a tight spiral, using the towel to help you. Leave the cake to cool completely in the towel, will help it retain its shape.
While the cake is cooling, make the jam filling. In a small saucepan, heat 1 cup of peach jam and 1 cup of raspberries over medium heat. Bring the mixture to a boil, then reduce the heat and let it simmer for 10-15 minutes, or until the fruit has broken down and the jam has thickened.
Once the cake has cooled, carefully unroll it and spread the jam filling over the surface, leaving a small border around the edges. Gently roll the cake back up, using the towel to help you again. Place the jam roll on a serving plate and sprinkle with powdered sugar, if desired.
The combination of sweet, juicy peaches and tangy raspberries is what really makes this jam roll stand out. The jam filling is bursting with flavor, perfectly complementing the light and fluffy sponge cake. Plus, the vibrant colors of the fruit make this dessert a stunning centerpiece for any table.
If you want to take this dessert to the next level, consider serving it with a scoop of vanilla ice cream or a dollop of whipped cream. The creamy, cool texture of the ice cream or whipped cream will balance out the sweetness of the jam roll and make for a truly decadent treat.
