7 tbsp (100 g) unsalted butter, softened
3/4 cup (90 g) powdered sugar Shop
1 tsp pure vanilla extract Shop
1/8 tsp salt
3 large egg whites (about 100 g), at room temperature
3/4 cup gluten-free all-purpose flour blend (about 100 g) Shop

Instructions

1 Preheat the oven to 375°F (190°C) and line two baking sheets with parchment. Fit a piping bag with a 1/2-inch plain tip.
2 Beat the butter and powdered sugar until very smooth and pale, about 2 minutes. Beat in the vanilla and salt.
3 Add the egg whites a little at a time, beating well after each addition. The batter may look slightly curdled; it will come together with the flour.
4 Fold in the gluten-free flour blend just until smooth. The batter should be soft enough to pipe but hold its shape.
5 Pipe fingers about 3 inches long, 2 inches apart, since they spread. Tap the sheet on the counter once to settle them.
6 Bake one sheet at a time for 8-10 minutes, until the edges are deep golden and the centers are pale.
7 Let them sit for 1 minute, then lift them onto a rack with a thin spatula. They crisp as they cool.

Tips & Notes

Have the egg whites at room temperature and add them slowly. Cold whites make the langue de chat batter split and the cookies bake up uneven.
Pipe the langue de chat in thin, even fingers and leave room between them. The batter spreads to about twice its width and thin cookies are the crisp ones.
Store langue de chat in an airtight tin as soon as they are cool. They soften quickly in humid air; a few minutes in a 300°F oven brings back the snap.
