Directions

1. Make the jam: Combine the frozen raspberries and sugar in a small deep-sided saucepan and bring to boil over a medium heat. When the sugar is melted, increase the heat and boil for another 4 minutes. Remove from the heat and add rose water. Transfer to a small container (pass it through a sieve if you’d rather not have seeds in your jam). Leave to cool and set.
2. Make the cookies: Preheat the oven to 375F. Line 3 baking sheets with baking parchment. Using a 2” round cutter as a guide, draw 8 circles on each sheet of paper, spaced well apart. Turn the paper over so the pencil marks are underneath.
3. Beat the butter, confectioner’s sugar and salt in a bowl until pale and fluffy. Sift in the flour and cornstarch and beat until thoroughly mixed. Spoon the mixture into a piping bag fitted with a medium star nozzle. Pipe 24 swirled rounds (not rosettes), inside the circles on the baking sheets. Refrigerate cookies for 15 minutes before baking (this will help cookies retain their shape).
4. Bake in the center of the oven for 13—15 minutes, until pale golden-brown. Cool on the baking sheets for 5 minutes then carefully transfer to a wire rack to cool completely.
5. Make Buttercream: Beat the butter, confectioner’s sugar and vanilla until fluffy and smooth. Spoon into a piping bag fitted with a medium star nozzle.
6. Assemble: Spoon a layer of jam onto the flat side of 12 of the cookies and place jam-side up on a cooling rack. Pipe an equal thickness of buttercream over the jam and sandwich with the remaining cookies. Dust with confectioner’s sugar. Share the love.
