Number Of Ingredients 8

10 tablespoons unsalted butter, plus more, room temperature, for pans
1 1/4 cups skin-on hazelnuts, divided
1/2 cup all-purpose flour
1/2 teaspoon kosher salt
1 vanilla bean, split lengthwise
2 tablespoons honey, preferably raw
3 large egg whites
3/4 cup (packed) dark brown sugar

Steps:

Preheat oven to 350°. Butter eight 3x2" mini loaf pans or a standard 12-cup muffin pan. Toast 1 cup hazelnuts on a small rimmed baking sheet, tossing occasionally, until golden brown, 8-10 minutes. Let cool (do not remove skins). Pulse hazelnuts, flour, and salt in a food processor until finely ground.
Place 10 Tbsp. butter in a small saucepan. Scrape in seeds from vanilla bean; add pod. Cook over medium heat, stirring often, until butter foams, then browns (do not let burn), 5-8 minutes. Discard pod and scrape vanilla butter into a medium bowl. Whisk in honey.
Increase oven heat to 400°. Whisk egg whites in a large bowl just to break up, add brown sugar, and whisk until mixture is smooth. Fold in dry ingredients in 2 additions, then fold in butter mixture just until smooth.
Coarsely chop remaining ¼ cup hazelnuts. Scrape batter into pans and top with hazelnuts. Bake financiers until golden brown and a tester inserted into the center comes out clean, 15-20 minutes for loaves, 10-15 for muffins. Let cool 5 minutes in pans, then transfer to a wire rack. Let cool completely.
DO AHEAD: Financiers can be made 1 day ahead. Store tightly wrapped at room temperature.
