I have had some sultanas and raisins macerating in vodka in the pantry left over from a Christmas party where I made Christmas pudding vodka shots, from a recipe from the wonderful Hairy Bikers:

So I used a basic sultana slice recipe to use up the fruit and tweaked it to make this rather boozy slice! I think you could add a lemon drizzle icing for aesthetic effect rather than taste enhancement.
Ingredients
1 1/2 cups self raising flour
1 level tsp cinnamon
1/2 cup hazelnut meal
1 cup sultanas and raisins soaked in vodka, muscat or port
1 cup caster sugar
1 egg, beaten
2 generous tablespoons golden syrup
4 tbl butter or olive oil spread
Method
Line a swiss roll tin with baking paper and preheat oven to 170 degrees C.
Heat butter/olive oil spread and golden syrup together until melted in the microwave and allow to cool.
Sift flour and cinnamon together into a bowl, add sugar, macerated fruit, beaten egg and golden syrup mixture, and mix well until combined.
Press into lined tin and bake for 25 minutes.
Let slice cool completely in tin before cutting into slices.
