Langes de Chat (Cat Tongue Cookies)

1 . Stage

Preheat the oven to 400 degrees F (200 degrees C). Lightly grease 2 baking sheets.

2 . Stage

Cream butter cubes for about 1 minute in a bowl with an electric mixer until smooth and the color has turned pale yellow. Add sugar and vanilla extract; continue the creaming process until the mixture is smooth. Beat in the egg whites, 1 at a time, on low speed until batter is light and fluffy. Mix in flour until just combined--do not overmix!

3 . Stage

Transfer batter into a pastry bag with a medium plain tip and pipe dough in 2-inch "tongues" onto the prepared baking sheets.

4 . Stage

Bake in the preheated oven until cat tongues turn golden brown on the edges, about 10 minutes.
