this Recipe

Ingredients:

• For the Langues de Chat Cookies:
• 125g (1 cup + 2 tablespoons) unsalted butter, softened
• 80g (2/3 cup) powdered sugar, sifted
• 1 large egg white, at room temperature
• 60g (1/2 cup) all-purpose flour, sifted
• 15g (2 tablespoons) cornstarch, sifted
• 1/4 teaspoon vanilla extract (optional, but recommended)
• Pinch of salt
• For the White Chocolate Filling:
• 200g (7 ounces) high-quality white chocolate, finely chopped
• 50ml (1/4 cup) heavy cream
• 15g (1 tablespoon) unsalted butter

Preparing the Langues de Chat Cookies

Okay, let’s get started with the cookie part! These are delicate and delicious, and the key is to be precise with your measurements and gentle with your mixing.

1. Cream the Butter and Sugar: In a large bowl, or the bowl of your stand mixer, cream together the softened butter and sifted powdered sugar until light and fluffy. This usually takes about 3-5 minutes. Make sure to scrape down the sides of the bowl occasionally to ensure everything is evenly incorporated. You want a smooth, pale mixture.
2. Incorporate the Egg White: Add the egg white to the butter and sugar mixture. Mix on medium speed until fully combined. Don’t overmix at this stage; just until it’s homogenous. Overmixing can develop gluten and make the cookies tough.
3. Add Vanilla Extract (Optional): If you’re using vanilla extract, add it now and mix briefly to combine. The vanilla adds a lovely subtle flavor that complements the white chocolate beautifully.
4. Sift in Dry Ingredients: In a separate bowl, whisk together the sifted all-purpose flour, sifted cornstarch, and salt. Sifting is crucial here to prevent lumps and ensure a light and airy cookie. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix! Overmixing will result in tough cookies. You want a smooth, pipeable batter.
5. Prepare the Piping Bag: Transfer the batter to a piping bag fitted with a small round tip (about 1/4 inch or 6mm). If you don’t have a piping bag, you can use a Ziploc bag and snip off a small corner.
6. Pipe the Cookies: Line two baking sheets with parchment paper or silicone baking mats. Pipe small, oval-shaped cookies onto the prepared baking sheets, leaving about 1 inch (2.5 cm) of space between each cookie. Aim for cookies that are about 2 inches (5 cm) long and 1 inch (2.5 cm) wide. Consistency in size is important for even baking and a professional look.
7. Bake the Cookies: Preheat your oven to 325°F (160°C). Bake the cookies for 8-12 minutes, or until the edges are lightly golden brown. Keep a close eye on them, as they can burn easily. The baking time will depend on your oven, so start checking them at 8 minutes.
8. Cool the Cookies: Once baked, remove the baking sheets from the oven and let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely. This prevents them from breaking while they are still soft.

Making the White Chocolate Filling

Now for the delicious white chocolate filling! This is a simple ganache, but using high-quality white chocolate is essential for the best flavor and texture.

1. Chop the White Chocolate: Finely chop the white chocolate and place it in a heatproof bowl. The finer you chop it, the easier it will melt.
2. Heat the Heavy Cream: In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer. Do not boil the cream.
3. Pour Cream over Chocolate: Pour the hot heavy cream over the chopped white chocolate. Let it sit for about 1 minute to allow the heat to melt the chocolate.
4. Stir Until Smooth: Gently stir the mixture until the white chocolate is completely melted and the ganache is smooth and glossy. If there are any unmelted pieces, you can microwave the mixture in 10-second intervals, stirring in between, until smooth.
5. Add Butter: Add the unsalted butter to the ganache and stir until it is fully incorporated and the ganache is even smoother and shinier. The butter adds richness and helps to stabilize the ganache.
6. Cool the Ganache: Let the ganache cool at room temperature for about 30 minutes, or until it has thickened slightly but is still spreadable. You don’t want it to be too firm, or it will be difficult to spread.

Assembling the Shiroi Koibito

Finally, the fun part – putting everything together! This is where the magic happens, and you transform simple cookies and ganache into a beautiful and delicious treat.

1. Pair the Cookies: Find cookies that are similar in size and shape. This will make the finished product look more uniform and professional.
2. Spread the Filling: Take one cookie and spread a generous amount of the white chocolate ganache on the flat side. Be careful not to spread it too close to the edges, as it will squeeze out when you sandwich the cookies together.
3. Sandwich the Cookies: Top the ganache-covered cookie with another cookie, flat side down. Gently press the cookies together to distribute the filling evenly.
4. Repeat: Repeat steps 2 and 3 with the remaining cookies and ganache.
5. Chill (Optional): For best results, chill the assembled Shiroi Koibito in the refrigerator for about 30 minutes to allow the ganache to set completely. This will make them easier to handle and prevent the filling from squeezing out.
6. Serve and Enjoy! Serve the Shiroi Koibito chilled or at room temperature. They are best enjoyed within a few days, as the cookies can soften over time.

Tips for Success

• Use High-Quality Ingredients: The quality of your ingredients will directly impact the flavor of the finished product. Use high-quality butter, white chocolate, and vanilla extract for the best results.
• Don’t Overmix the Cookie Dough: Overmixing develops gluten, which can make the cookies tough. Mix the dough until just combined.
• Bake Evenly: Make sure your oven is properly calibrated and that the cookies are evenly spaced on the baking sheets to ensure even baking.
• Cool Completely: Allow the cookies to cool completely before assembling them. This will prevent the ganache from melting and making the cookies soggy.
• Store Properly: Store the assembled Shiroi Koibito in an airtight container in the refrigerator to keep them fresh.

Variations

• Dark Chocolate Filling: Substitute the white chocolate with dark chocolate for a richer, more intense flavor.
• Matcha Filling: Add matcha powder to the white chocolate ganache for a Japanese-inspired twist.
• Citrus Zest: Add lemon or orange zest to the cookie dough for a bright, citrusy flavor.
