1. Place the milk and yeast in the bowl fitted with the kneading/crushing blade. Warm at speed 5 at 100°F for 3 minutes. Add 1 egg, flour, ground almonds, salt, sugar and butter. Launch the P2 pastry program. After 3 minutes 30 seconds of mixing, your dough should be shaped like a ball. Be careful to leave it in the Prep&Cook to rise for the next 40 minutes of the program.
2. At the end of the program, form dough into 8 balls and place in a greased 9-inch round cake pan; pack tightly together. Let dough rise for 1 hour away from drafts.
3. Preheat the oven to 350°F.
4. Beat the remaining egg and brush on the brioche. Sprinkle with granulated sugar and bake for 45 minutes. Let cool. Sprinkle with powdered sugar before serving.
