Cat tongue cookies are light, crisp, and buttery treats that melt in your mouth. Known as Lidah Kucing in Indonesia, these long, thin cookies are similar to the French Langues de Chat and Japanese Cat’s Tongue Biscuits, but with their own rich, buttery twist.
In a bowl, add room-temperature butter, powdered sugar, salt, and vanilla extract. Gently mix with a spatula first to prevent the sugar from scattering when you start the hand mixer. Beat until the butter mixture becomes light, pale, and creamy.
Sift in the flour and milk powder. Use a spatula to fold lightly before mixing with the hand mixer. While mixing, gradually pour in the egg whites until everything is well incorporated. Transfer the smooth batter into a piping bag.
Pipe the batter onto a cat tongue cookies pan, or a regular flat baking tray if you don’t have one. Make each strip about 5–6 cm long. Bake in a preheated oven at 285°F (140°C) for about 24 minutes, turning the pan halfway through for even coloring. Let the cookies cool completely on a rack before storing in an airtight jar. Enjoy your crisp, buttery cat tongue cookies!

Notes
Use good-quality butter. It’s the soul of this recipe , better butter means richer aroma and flavor.
Bring ingredients to room temperature. Soft butter and egg whites mix more smoothly, giving the cookies an even texture.
Don’t overmix the batter. Once the flour is incorporated, stop mixing to keep the cookies crisp and delicate.
Pipe evenly. Aim for 5–6 cm strips with consistent thickness so they bake evenly and brown at the same time.
Rotate the tray halfway. Turning the tray at 12 minutes ensures the cookies bake evenly, especially in smaller ovens.
Cool completely before storing. Any leftover warmth can trap moisture and make the cookies lose their crispness.
Store in an airtight jar. These cat tongue cookies stay crisp for up to two weeks when stored properly in a dry place.
