Lusikkaleivät - Finnish Spoon Biscuits

When I was making these this hot and humid morning I realised that these biscuits are actually perfect for a warm climate; there's no rolling and cutting and no chilling the dough over and over again, just spooning. How simple is that? My mum always used to make these and she still does, but unfortunately mailing them to me would take too long, thus I needed to make them myself.
These take me right back to childhood!

Lusikkaleivät - Finnish Spoon Biscuits

200 g butter

1 1/2 dl sugar

2 tsp vanilla sugar

1 tsp bicarb soda

4 dl plain flour

raspberry conserve

caster sugar

Melt butter in a pan and let bubble for a few minutes, but don't let it brown. Transfer the hot butter in a bowl and add sugar. Let cool, then stir. Add the dry ingredients and mix well. Use a small deep spoon to take spoonfuls of the dough and place on a baking tray lined with baking paper. Bake in 175C for 15 minutes or until lightly brown. Let cool, then spread some raspberry conserve on half of the biscuits and place the other halves on top. Roll in caster sugar.
