Cream the butter and
sugar in a small bowl
with an electric beater
until light and fluffy.
Add the vanilla essence
and egg and beat until
well combined. Transfer
to a large bowl and add
the sifted flour, mixed
spice, ginger and baking
powder.
Using a knife,
mix to a soft dough.
Gather together, then
divide the mixture into
2 portions.
Roll
one portion out on to a
rectangle about 3mm/1/8in
thick and trim the
edges. Repeat with the
other dough portion and
refrigerate both until
just firm.
Preheat the
oven to 180°C/350°F/Gas
mark 4. Line 2 baking
trays with baking
parchment.
Spread each
dough rectangle with
mincemeat, then roll up
like a Swiss roll. Cut
the rolls into slices
about 1cm/1/2in thick.
Place on the prepared
trays, leaving space
between each slice.
Bake
for 10 to 15 minutes, or
until golden. Cool on the
trays for 3 minutes
before transferring to a
wire rack to cool
completely.
