Here are mine:
Result? Mum even liked the chocolate layers!! I will be making these again. They did melt in my mouth.
40g icing sugar
110g self-raising flour
1 tablespoon cocoa
1 tablespoon jam (strawberry would be good - I used 'black forest' as I didn't have strawberry)
red food colouring
Preheat oven to 160 degrees celcius (fan forced). Cream butter and sugar until fluffy. Add flours and mix until combined (I found it easier to use clean hands). Separate dough into three bowls. Add vanilla essence to one, jam and red food colouring to one and cocoa to the other. You may need to add some extra flour to the one with jam. Combine ingredients.
Take small amounts of dough, roll into a ball. Place onto lined baking trays. Squish down with a fork (makes the pretty lines). Bake for 10 minutes (may need longer if you make bigger biscuits). Cool on baking racks.
Mix icing sugar with vanilla essence and a little water until combined and thick. Use to join together strawberry and chocolate biscuits.
Add nutella to icing mixture (add more icing sugar and water as necessary). Use to join together strawberry and vanilla biscuits.
In a new bowl, add icing sugar and jam (you may not need water for this one). Use to join together vanilla and chocolate biscuits.
Leave for icing to harden.
