Plum Clafoutis

Ingredients
2 tablespoons melted and cooled butter, plus softened butter for greasing the pan
1/4 cup sugar, plus 1 tablespoon I use cane sugar
3/4 pound fresh plums (about 8 small-medium sized) washed, pitted and sliced into wedges
3 eggs
pinch of kosher salt
1/2 cup all-purpose unbleached flour
1 cup whole milk
1 teaspoon vanilla extract
icing sugar for serving, optional

Instructions
Preheat the oven to 375F.
Grease the bottom and sides of a 9-inch tart pan, or similar-size baking dish, with softened butter. Dust the bottom of the pan with 1 tablespoon sugar. Arrange the plum slices on the bottom of the pan.
In a medium bowl, or large measuring cup, whisk the eggs until smooth. Add in the sugar, salt, and flour and whisk again until smooth. Stir in the melted butter and vanilla then slowly pour in the milk. Whisk until a smooth batter forms.
Pour the batter over the plums. If your dish is very full, you may want to place it on a baking sheet to catch any drips. Carefully transfer to oven and bake until the clafoutis is nicely puffed and golden, and just set in the center, about 30-35 minutes.
Let cool slightly and dust with powdered sugar just before serving, if desired.
