Linnaeus Cookies Recipe
A classic holiday cookie with buttery, tender layers and a fruity jam filling. Follow these detailed steps for perfect results every time.
Ingredients (makes about 20-30 sandwich cookies depending on cutter size)
For the Dough:
- 300g (2 ½ cups) plain flour
- 200g (1 cup) unsalted butter (cold and cut into cubes)
- 100g (½ cup) granulated sugar
- 2 large egg yolks
- Optional flavorings:
- 1 tsp cinnamon
- 1 tbsp cocoa powder
- 1 tsp gingerbread spice mix
- ½ tsp vanilla or almond extract
- Zest of 1 lemon (a personal favorite that balances the sweetness beautifully)
For Assembling:
- Your favorite jam or marmalade (raspberry, apricot, or redcurrant are traditional options)
- Powdered sugar for dusting
Step-by-Step Instructions
1. Make the Dough
- Combine Dry Ingredients:
- In a large mixing bowl, whisk together the flour, sugar, and any optional spices (if using).
- Add Butter and Egg Yolks:
- Add the cold butter cubes and egg yolks to the bowl.
- Use your fingers or a pastry cutter to rub the butter into the flour mixture until it resembles coarse crumbs.
- Knead Quickly:
- Bring the dough together by kneading lightly and quickly to prevent the butter from melting.
- The dough should form a smooth ball. If it feels dry, add 1-2 teaspoons of cold water.
- Divide and Chill:
- Divide the dough in half and flatten each into a disc. Roll each disc between two sheets of parchment paper to about 3-4mm (⅛ inch) thickness.
- Transfer the rolled dough (still sandwiched in parchment) onto a baking sheet and refrigerate overnight, or for at least 1-2 hours.
2. Cut the Shapes
- Preheat the Oven:
- Preheat your oven to 175°C (350°F). Line baking sheets with parchment paper or silicone baking mats.
- Cut the Cookies:
- Dust the chilled dough lightly with flour using a sieve to prevent sticking.
- Use cookie cutters to cut your desired shapes, making sure to cut an equal number of solid and “window” pieces.
- Re-roll scraps between parchment, chill briefly if needed, and continue cutting until all dough is used.
- Arrange on Baking Sheets:
- Place the cut shapes on the prepared baking sheets, leaving about 1-2 cm (½ inch) of space between cookies.
3. Bake the Cookies
- Bake in Batches:
- Bake one sheet at a time in the preheated oven for 8-10 minutes, or until the edges are just starting to turn golden.
- Cool Completely:
- Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack. The cookies will be fragile while warm, so handle with care.
4. Assemble the Linzer Cookies
- Prepare the Jam Filling:
- Warm the jam slightly in a small saucepan or microwave to make it spreadable. If desired, strain the jam to remove any seeds for a smoother texture.
- Dust the Tops:
- Sift powdered sugar over the “window” cookies (the ones with cutouts) before assembling.
- Spread the Jam:
- Spread about ½ teaspoon of jam on the flat side of the solid cookies.
- Sandwich the Cookies:
- Gently press a “window” cookie on top of the jam-covered base. Repeat with the remaining cookies.
Pro Tips for Perfect Linzer Cookies:
- Work with Cold Dough:
- Keep the dough chilled while cutting shapes. If it becomes too soft, pop it back into the refrigerator for 10-15 minutes.
- Use the Right Tools:
- A perforated silicone mat ensures even baking, while a sharp cutter preserves clean edges.
- Size Matters:
- Smaller cookies bake more evenly and are easier to handle. Stick to cutters about 2-3 inches in diameter.
- Assemble with Care:
- Wait until the cookies are completely cool before adding jam to prevent breakage.
- Store Smart:
- Store assembled cookies in an airtight container at room temperature for up to 5 days. Separate layers with parchment paper to prevent sticking.
With these detailed steps and tips, your Linzer cookies will be not only delicious but also stunningly beautiful. Perfect for holiday gift boxes or dessert platters! Happy baking! 🎄
