Preheat the oven to 180°C/Fan
160°C/Gas 4. Use an electric whisk
to mix the butter and sugar in a
bowl until light and creamy. Add
the eggs and whisk again. Fold
in the flour, baking powder and
buttermilk or sour cream using a
spatula, until incorporated.
. Fold the vanilla into the cake
batter and divide the mixture
equally between the prepared
cake rings. You can do this either
by spooning the batter in, or by
putting the batter in a piping bag
and piping it in neatly. Bake in the
preheated oven for 15–20 minutes,
until the cakes are golden brown
and spring back to the touch.
Leave the cakes to cool in
the rings for a few minutes, then
remove by sliding a sharp knife around the inside of each ring.
Transfer the cakes to a wire rack and
leave to cool completely.
When you are ready to serve,
whip the cream to stiff peaks using
a whisk. Spoon the cream into the
piping bag with a round nozzle. Cut
each cake into thirds horizontally
using a large serrated knife. Spoon
a little jam onto the bottom third
of each cake and then pipe a swirl
of cream on top. Top each with
the middle slice of cake and a little
more jam and cream.
Finish each cake with the cake
top and dust with icing sugar. Pipe
a little cream on the top of each
cake in the middle and fix a rose in
place. The flowers are for decorative
purposes only and should be
removed as you cut the cake.
