Preheat the oven to 180c /160c fan/gas mark 4.
Line a baking tray with parchment paper and set aside.
In a large bowl, cream the butter and icing sugar until light and fluffy.
In two batches, sieve in the cornflour and plain flour. Mix until combined.
Use your hands to make a ball shape from the dough. Wrap the ball in cling film. Place it in the fridge while you prepare your strawberries and make your buttercream.
To prepare the strawberries, wash them, dry them and chop off the green tops. Press the berries through the sieve to break them up.
To make your buttercream, mix the butter and icing sugar. Add in the sifted strawberries and a drop of Red food colouring
Once your dough is chilled, take it out of the fridge and roll it out onto a floured surface, if its sticky or too soft add more flour if needed
Use a 5-inch cookie cutter to cut out 20 cookies.
Transfer the cookies to the baking tray and cook for 15-20 minutes, until slightly golden.
Allow the cookies to cool on a wire rack.
Once cooled, spread or pipe a little buttercream in the centre of each cookie. Pair the cookies up to make sandwiches.
Enjoy sharing and eating your scrumptious strawberry shortcake sandwiches.
