Step 1
Cream together the softened butter & sugar until light & fluffy.
Step 2
Add the egg and vanilla and continue mixing until combined. Sift in the flour add the salt and freeze dried raspberry pieces and mix until a dough is formed.
Step 3
Lightly flour your surface, then roll the dough out to around 1cm thick. Using a round cutter (or a glass!) cut out rounds. Set aside half of your rounds and, using a small round cutter (or a piping tip), stamp out the centre of them.* These will be your biscuit tops.
Step 4
Bake for around 10 minutes, or until the edges are golden brown.
Step 5
Remove biscuits from the oven and allow to cool completely.
Step 6
Take a teaspoon of raspberry jam and drop it in the middle of your whole biscuits.
Step 7
Take your biscuit tops, and use something straight (I used a cake scraper) to cover half. Dust icing sugar over the top, leaving you with a half iced biscuit. This is an optional way to decorate but creates a nice effect!
Step 8
Place the biscuit tops over the jammy biscuit rounds, and gently press down to sandwich together. Enjoy!
*The number of biscuits you will get will vary depending on the size of cutter you use - this will also affect bake time (expect a longer bake for bigger biscuits).
