This video carefully demonstrates how to make Victoria sponge cake. Mix room temperature butter and powdered sugar until fluffy and creamy, then gradually add beaten eggs warmed in a double boiler to emulsify. Sift in cake flour and baking powder and mix lightly, then pour the batter, adjusted with milk, into a mold and bake in the oven. Once the sponge cake has cooled, layer it with homemade raspberry jam and whipped cream, and decorate with powdered sugar, fresh berries, and rosemary to finish. The fluffy texture of the cake, the sweet and sour jam, and the smooth cream are in perfect harmony, making this a beautiful treat perfect for a home café or for entertaining guests.
