Pink Grapefruit Sandwich Cookies

For the month of September, the Cookie Carnival recipe is Pink Grapefruit Sandwich Cookies. I wasn't really sure what to expect from them, but since I *love* lemon, I thought I would like them. And the verdict is...I do like them. Next time, I will add a little more of the grapefruit juice for a stronger tartness, but I have already ate 3 of them. If you are a little worried about not liking them, go ahead and try them. They are sweet with a little hint of the grapefruit. There is not a strong grapefruit flavor to them, and I am sure that you will like them!


Pink Grapefruit Sandwich Cookies
You can bake the cookies and make the filling a day ahead.
Ingredients for cookies
Makes 15 sandwich cookies.
* Grated zest of 1 Ruby Red grapefruit, plus 1/4 cup freshly squeezed juice
* 1 cup sugar
* 1 1/2 cups all-purpose flour, plus more for work surface
* 3/4 cup cake flour (not self-rising)
* 1 teaspoon baking powder
* 1/2 teaspoon salt
* 1/2 cup (1 stick) unsalted butter, softened
* 2 large egg yolks
* Pink Grapefruit Cream Filling

Directions
1. Preheat oven to 350 degrees. Line a baking sheet with parchment paper; set aside. In a small bowl, combine zest with 1 tablespoon sugar; set aside. In a medium bowl, whisk together both flours, baking powder, and salt; set aside.
2. In the bowl of an electric mixer fitted with the paddle attachment, beat butter and remaining sugar on medium-high speed until light and fluffy, about 2 minutes, scraping down sides of bowl as needed. Add egg yolks, and beat until combined, scraping down sides of bowl as needed. Beat in reserved zest-sugar mixture. Add flour mixture in two batches, alternating with the juice, and beat to combine.
3. Turn out dough onto a piece of plastic wrap, and shape into a 1-inch-thick disk. Wrap in plastic, and refrigerate until firm, about 30 minutes.

4. On a lightly floured work surface, roll out disk to 1/8 inch thick using a lightly floured rolling pin. Using a lightly floured 2-inch round cookie cutter, cut out rounds and place about 1 inch apart on prepared sheet. Bake, rotating sheet halfway through, until edges are golden, 18 to 20 minutes. Transfer sheet to a wire rack to cool 5 minutes. Transfer parchment paper and cookies to rack to cool completely.

5. Using an offset spatula, spread 1 tablespoon filling onto flat sides of half the cookies. Sandwich with remaining cookies, keeping flat sides down. Once filled, cookies can be kept in an airtight container in the refrigerator for up to 3 days.
