Instructions

• 1. Preheat the oven to 170℃ and line two baking trays with baking parchment.
• 2. Mix together the softened butter and icing sugar in a bowl using an electric hand whisk.
• 3. Add the egg whites, a little at the time, and mix until smooth.
• 4. Add the sifted flour and mix. Add the heavy cream and mix.
• 5. Pipe the mixture into rectangular shapes or use the mold to shape them up (I used a silicone kitchen mat to make the mold in the pictures).
• 6. Bake in the preheated oven at 170C for 6~8 mins or until the edges turn nicely golden brown.
• 7. Transfer to a wire rack to cool.
• 8. Melt the chocolate and put some of it on a cookie. Cover it with another cookie. Repeat for the rest of the cookies.
• NOTE : You can also use the cookie mold to shape the chocolate into squares. Spread the melted chocolate in the mold, remove the mold and put it in the fridge until firm.
