Makes 6
| | Butter (for the molds) 1/2 cup granulated sugar, plus more forthe molds 1 cup all-purpose flour 1/3 cup almond flour 1 teaspoon baking powder Pinch of salt 1 vanilla bean, split 7 tablespoons butter, at room temperature 3 eggs 1/2 cup whole milk 1/3 cup bittersweet chocolate (70 percent cacao), chopped coarsely 1/3 cup pecans, chopped coarsely, plus 6 extra pecan halves 1/3 cup unsalted shelled green pistachios, chopped coarsely Confectioners' sugar (for sprinkling) 1. Set the oven at 350 degrees. Butter 6 round individual paper cups or a regular muffin tin. Coat inside surfaces with sugar, tapping out the excess.
2. In a medium bowl, combine the all-purpose flour, almond flour, baking powder, and salt. Scrape the vanilla seeds into the mixture.
3. In an electric mixer, beat the butter for 1 minute. Add the 1/2 cup of granulated sugar and beat for 1 minute more, or until mixture is light and fluffy. Beat in the eggs, one by one. Add the milk and beat just until combined. With the mixer set on its lowest speed, slowly beat in the flour mixture.
4. Remove the bowl from the mixer stand. Fold in the chocolate, chopped pecans, and 1/4 cup of the chopped pistachios. Divide the batter among the baking cups, filling each about 3/4 full. Top with 1 pecan half each and some of the remaining pistachios. Bake the muffins for 30 minutes or until a toothpick inserted into the center comes out clean. Let them cool in the molds. Sprinkle with confectioners' sugar. Béatrice Peltre
