Vanilla Bean Financiers

Ever since I found out about financiers, I've been wanting to make them.  They are French cakelets made with brown butter and almond flour, and traditionally baked in a financier mold (I really want one, but haven't gotten myself one yet).  Some people say a bakery near Paris' financial district started making these cookies and calling them financiers because they're shaped like bars of gold.  Others say they are called that because they're so rich that only financiers can afford to eat them.

Either way, I knew I was going to love the combination of brown butter and almond flour, and I did!  I added vanilla bean because I love the taste of vanilla and almond together, but to be more traditional you could leave the vanilla out.  If you make this version, you'll notice beautiful little flecks in two shades of brown: dark brown from the vanilla bean seeds and golden brown from the brown butter.  So pretty!

Once I get my financier pans, I want to try making some fruit-studded financiers--maybe a few raspberries or thin slices of peach on top.

These financiers are best warm and fresh from the oven, but are also delicious the next day, especially dunked in some milk or coffee.

Ingredients (makes 18 mini-muffin sized financiers; adapted from Dorie Greenspan's recipe):

1 1/2 sticks (12 tablespoons) unsalted butter
1 cup sugar
1 cup almond flour
6 egg whites
1/2 vanilla bean
1 cup flour*

In a medium saucepan, melt the butter over medium heat.  Continue to cook, swirling the pan occasionally, until the butter comes to a boil and browns.  As soon as the butter browns, remove the pan from the heat.  (If you haven't browned butter before, check out this step-by-step tutorial from How Sweet It Is.)

In another saucepan, stir together the sugar and almond flour.  Scrape in the seeds from the vanilla bean.  Using your fingers, rub the mixture to evenly distribute the vanilla.  Stir in the egg whites.  Heat the mixture over low heat, stirring constantly with a wooden spoon, until the mixture is runny, lightened, and hot.

Remove from the heat and stir in the flour.  Gradually mix in the butter.

Refrigerate the batter for at least one hour, or up to three days, with plastic wrap right on top of the surface to keep out air.

Preheat your oven to 400.  Butter mini muffin tins or financier molds, then dust with flour and tap out any extra.  Fill molds almost to the top with batter and bake for 10-13 minutes, until puffed, golden brown around the edges, and set.

Turn out financiers onto a wire rack and cool to room temperature (or enjoy them warm).

*The recipe only called for 2/3 of a cup and I meant to follow it exactly except for the addition of the vanilla bean, but read the quantity wrong when I glanced at the recipe before adding the flour.  The cookies still turned out great.  You could try them with 2/3 or a full cup of flour; I just wanted to report exactly what I did.  Next time I'll check twice!
