Hazelnut Babycakes

Technically, I suppose these little nibbles would be classified as a version of financiers or friands.

Hazelnut babycakes come together fairly quickly- charming little bites that are as nice to eat as they are simple to make.
They make a sweet little nibble with tea or coffee in the afternoon, crispy on the top and edges, and chewy within.

A treat to be sure, perhaps a little more rare these days if you're trying to be more careful- but they're meant to be shared.
Of course, you could use a different pan if you don't have this particular style. Just keep in mind that you'll be dealing with a different bake time and will likely have to be a bit more attentive at some point.
(Although I think these particular cakes are best in a small size because of their density.)

Hazelnut Babycakes
makes 24

1 c (100 g) hazelnut meal
1/4 c plus 1T (50 g) arrowroot powder
1/4 t (2 g) salt
1/2 t (2 g) baking powder
2 large eggs, plus one egg white- room temperature
10 T butter (about 140 g), melted and slightly cooled
1/2 c (100g) granulated sugar

Options:
raspberries or blackberries (or blackberry or raspberry jam)
chocolate (solid pieces to tuck in the center, or as a ganache to dip the tops)
a bit of espresso powder in the batter (especially if you add chocolate)

Preheat the oven to 375 F/190 C with a rack set in the center.
Butter the holes of a 24-hole mini muffin tin.
Blend the hazelnut meal, arrowroot, salt, and baking powder together in a medium bowl and set aside.
In a large bowl, whisk the eggs and extra white together with the sugar a few minutes so the eggs are broken down and the sugar is well incorporated. Add espresso powder here if you choose to use it.
Add the melted butter and mix well.
Pour the hazelnut mixture you've previously set aside into the eggs, sugar, and butter. Mix with a rubber spatula, until just homogeneous.
Divide the batter among the spaces in the muffin tin, they should be about 3/4 full.
Now it's time to dress them up a bit if you wish. Tuck a berry into the top of each, pressing it down slightly to sink it in (but try not to hit the bottom of the pan). Or, add some chopped chocolate, or a tiny dollop of jam to the center of each cake.

Bake the cakes 15-20 minutes, or until they are golden and puffed. Remove the pan from the oven and let cool only a couple minutes before turning the cakes out onto a cooling rack (they may need a little assistance- just don't make the mistake of waiting until completely cool because by then they've glued themselves to the pan).
Let cool completely, dust with powdered sugar (or dip the tops in ganache if you choose), and serve.
