Step-by-Step Instructions

Ready to dive into the delicious world of Square Langue de Chat Sandwich Cookies? Here’s a detailed, easy-to-follow guide to help you create these delightful treats, from mixing the dough to assembling the cookies. Whether you’re a seasoned baker or just starting, these steps will ensure your cookies turn out perfect every time.

1. Preheat and Prep

Start by preheating your oven to 350°F (175°C) before you begin mixing the ingredients. This step is crucial as it ensures the cookies bake evenly and turn golden brown.Place parchment paper or a silicone baking mat on a baking sheet to avoid sticking.

2. Mix the Dry Ingredients

In a medium bowl, sift together:

• 1 1/2 cups all-purpose flour
• 1/2 teaspoon baking powder
• A pinch of salt

Sifting the dry ingredients ensures there are no lumps and helps the dough achieve the perfect texture.

3. Cream the Butter and Sugar

In a large bowl, beat together:

• 1/2 cup unsalted butter, softened
• 1/3 cup powdered sugar

Whisk the mixture on medium speed until it turns light and airy.This step is essential for creating a soft, tender texture in your cookies.

4. Add the Egg and Vanilla

Once the butter and sugar are creamed, add:

• 1 large egg
• 1 teaspoon vanilla extract

Mix these ingredients until smooth. The egg will bind the dough, while the vanilla enhances the flavor, giving your cookies that irresistible aroma.

5. Combine the Dry and Wet Ingredients

Slowly incorporate the dry ingredients into the wet ingredients, mixing until everything is just combined.Take care not to mix too much, as this could impact the texture of your cookies.

6. Shape the Cookies

Now comes the fun part! Use a small spoon or cookie scoop to drop rounded portions of dough onto your prepared baking sheet. Leave enough space between each cookie to allow them to spread slightly as they bake.

For a unique touch, try shaping them into little squares or rectangles, giving your cookies that signature “square” look.

7. Bake the Cookies

Place the baking sheet in the preheated oven and bake for 10–12 minutes or until the edges are slightly golden. Keep an eye on them towards the end, as oven temperatures can vary.

Once done, let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.

8. Prepare the Filling

While your cookies cool, whip up a simple filling. In a small bowl, mix:

• 1/4 cup butter, softened
• 1/2 cup powdered sugar
• 1 teaspoon vanilla extract

Beat until smooth and creamy. You can adjust the consistency by adding more powdered sugar if necessary.

9. Assemble the Sandwiches

Once the cookies are fully cooled, take one cookie and spread a generous amount of filling on the flat side. Top with another cookie, pressing gently to sandwich them together. Continue this process with the rest of the cookies.

5 Tips for Perfecting Your Square Langue de Chat Sandwich Cookies

1. Bring Ingredients to Room Temperature: 

Make sure your butter and eggs are at room temperature before using them. This ensures the dough mixes well, leading to a smoother and softer cookie texture.

2. Don’t Overmix the Dough: 

When you combine the wet and dry ingredients, mix just until everything is incorporated. Mixing too much can result in tough cookies, so stop once the dry flour is fully incorporated and no longer visible.

3. Chill the Dough: 

If you have time, chill the cookie dough for at least 30 minutes before baking. This helps the cookies hold their shape and results in a slightly thicker, chewier cookie.

4. Check Your Oven Temperature: 

Every oven is different, so be sure to use an oven thermometer to confirm it’s at the right temperature (350°F/175°C). This will ensure your cookies bake evenly and don’t spread too much.

5. Play with Fillings: 

The filling doesn’t have to be just one flavor! You can switch it up based on your preferences, think chocolate ganache, flavored buttercream, or even fruit preserves for a twist.

With these tips, you’ll be well on your way to creating the perfect cookie sandwiches that everyone will love! Happy baking.
