In a large bowl whisk together the flour, sugar, baking powder and salt, add the butter and combine to form coarse crumbs, add the egg and puree and mix until almost combined. Move to a flat surface and form into a compact dough. Wrap in plastic and refrigerate for 1-2 hours.
Roll the dough to a little thicker then ⅛ thickness and cut out with a small round cookie cutter (about 1-1 1/2 inches). Place the cutouts on parchment paper lined cookie sheets. Half the rounds cut out a small hole using the tip of pastry nozzle. While the oven is pre-heating refrigerate the cookies for 15-20 minutes.
Pre-heat the oven to 350F (180C).
Bake the cookies for 8-10 minutes. Let cool on the cookie sheet 5-10 minutes then move to a wire rack to cool completely. Place some filling on each of the whole cookies and top with the holed cookie. Enjoy!
FOR THE FILLING
In a medium bowl add the icing sugar, cream cheese, strawberry puree and cream, mix until thick. If needed add more sugar or puree. Refrigerate until ready to use.
