1. Prepare the Raspberry Swirl Filling
- In a small saucepan, combine the raspberries, sugar, and lemon juice.
- Cook over medium heat, stirring occasionally, until the raspberries break down and the mixture thickens, about 5–7 minutes.
- Remove from heat and strain the mixture through a fine-mesh sieve to remove seeds. Allow the smooth raspberry puree to cool completely.
2. Make the Shortbread Dough
- In a large mixing bowl, beat the softened butter and powdered sugar together with an electric mixer until light and fluffy, about 2 minutes.
- Add the vanilla extract and mix until combined.
- In a separate bowl, whisk together the all-purpose flour, cornstarch, and salt.
- Gradually add the dry ingredients to the butter mixture, mixing until the dough comes together. Be careful not to overmix.
3. Roll Out the Dough
- Divide the dough into two equal portions for easier handling.
- Roll out each portion of dough on a piece of parchment paper into a rectangle, about 1/4 inch thick.
- Spread a thin layer of the cooled raspberry puree evenly over the surface of one dough rectangle, leaving a small border around the edges.
4. Create the Swirl
- Carefully roll up the dough from one long side into a tight log, using the parchment paper to help guide the rolling process.
- Repeat the process with the second portion of dough and raspberry puree.
- Wrap each dough log tightly in plastic wrap and refrigerate for at least 2 hours or until firm. Chilling is essential for clean slices and well-defined swirls.
5. Slice and Bake
- Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
- Remove the chilled dough logs from the refrigerator and slice into 1/4-inch thick rounds using a sharp knife.
- Place the cookie slices on the prepared baking sheets, spacing them about 1 inch apart.
- Bake for 12–15 minutes, or until the edges are lightly golden. Be careful not to overbake, as shortbread should remain pale and tender.
6. Cool and Serve
- Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
- Serve the cookies as they are, or dust with powdered sugar for an extra touch of elegance.
Tips for Perfect Raspberry Swirl Shortbread Cookies
- Chill the Dough: Chilling the dough is crucial for clean slicing and to prevent the cookies from spreading during baking.
- Use Fresh Ingredients: Fresh raspberries provide the best flavor, but frozen raspberries work well too if fresh ones aren’t available.
- Experiment with Flavors: Substitute the raspberry puree with other fruit fillings like strawberry, blueberry, or even apricot for a twist.
- Store Properly: Store the cookies in an airtight container at room temperature for up to a week or freeze them for longer shelf life.
