# What You'll Need:
→ Dry Ingredients
01 - 2 cups all-purpose flour (250 g)
02 - 1 cup finely ground blanched almonds (almond flour) (100 g)
03 - 1/2 teaspoon ground cinnamon
04 - 1/4 teaspoon salt
→ Wet Ingredients
05 - 3/4 cup unsalted butter, softened (170 g)
06 - 2/3 cup powdered sugar (80 g)
07 - 1 large egg yolk
08 - 1 teaspoon pure vanilla extract
09 - 1/2 teaspoon grated lemon zest
→ Filling & Finishing
10 - 3/4 cup seedless raspberry jam (225 g)
11 - 1/4 cup powdered sugar, for dusting (30 g)
# How to Make It:
01 - In a medium bowl, whisk together the all-purpose flour, almond flour, ground cinnamon, and salt until evenly blended.
02 - In a large bowl, beat the softened unsalted butter and powdered sugar using an electric mixer until the mixture is light and creamy.
03 - Add the egg yolk, pure vanilla extract, and grated lemon zest to the butter mixture; beat thoroughly until fully combined.
04 - Gradually add the dry ingredient mixture to the wet ingredients, mixing gently just until a dough forms without overworking.
05 - Divide the dough into two equal portions; shape each into a flattened disk, wrap in plastic wrap, and refrigerate for at least 1 hour.
06 - Preheat the oven to 350°F (175°C) and line two baking sheets with parchment paper.
07 - On a lightly floured surface, roll out one disk of dough to a thickness of 1/8 inch (3 mm).
08 - Use a 2-inch (5 cm) round or fluted cookie cutter to cut out cookies, placing half of them onto the prepared baking sheets.
09 - With a smaller 1-inch (2.5 cm) cutter, cut out the centers of the remaining cookies to create pastries with window or lattice tops.
10 - Gather and re-roll any leftover dough pieces as necessary to maximize yield.
11 - Bake the cookies in the preheated oven for 10 to 12 minutes, or until the edges turn lightly golden. Allow to cool on the baking sheets for 2 minutes, then transfer to a wire rack to cool completely.
12 - Once cooled, dust the cutout top cookies with powdered sugar.
13 - Spread approximately 1 teaspoon of seedless raspberry jam on the flat side of each whole bottom cookie.
14 - Place the sugared top cookies over the jam-covered bottoms to form sandwiches. Allow the cookies to rest for at least 30 minutes so the filling can set properly before serving.
