I've adapted these cookies from Martha Stewart. They were originally Lime Flowers, but the first time I made them I only had lemon, so I substituted that, and they were a huge hit. The only problem with these cookies is that one batch of dough doesn't make enough!!
2 cups flour (plus more for work surface)
1/2 teaspoon baking powder
1/4 teaspoon kosher salt
1 cup granulated sugar
2 tablespoon finely grated lemon zest
1/4 cup lemon juice
1 1/2 sticks butter
1 teaspoon vanilla extract
Sift together flour, baking powder and salt into a bowl.
Put granulated sugar and lemon zest in the bowl of an electric mixer fitted with the paddle attachment. Mix on medium speed 1 minute. Add butter and mix until fluffy, about 2 minutes. Mix in vanilla and lemon juice. Reduce speed to low and gradually mix in flour mixture.
On a lightly floured work surface, halve the dough. Flatten each half into a 10 inch disk, and warp each in plastic. Freeze until firm, about t 30 mins.
Preheat oven to 325F. Working with 1 half at a time, roll out dough on parchment paper to 1/8 inch thick. cut shapes from dough with a 3 inch flower shape cookie cutter. Space 1 inch apart on baking sheets lined with parchment paper. Cut a hole in centre of each with a 1-inch round cutter, repeat with remaining disk. Warp scraps in plastic. Freeze 30 mins, reroll, and cut.
Bake cookies, rotating sheets halfway through, until set, about 12 minutes. Let cool on a wire rack. Before serving sift confectioners sugar over cookies.
UPDATE: Dee let me know that I had a typo and had 1/2 cup lemon juice in the cookie batter and it should be 1/4 cup. So sorry to anyone who made it and the batter was too runny or too lemony!!!! If it worked with 1/2 cup let me know!!
