¼ cup (57 grams) mashed ripe banana (about 1 medium banana)
1 teaspoon (6 grams) vanilla bean paste
1 large egg (50 grams), lightly beaten
Softened butter, to serve
Instructions
Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a large bowl, sift together flour, powdered peanut butter, sugar, baking powder, cinnamon, ginger, nutmeg, cloves and cardamom Whisk in salt. Using a pastry blender or 2 forks, cut in cold butter until mixture resembles coarse bread crumbs.
In a small bowl, whisk together cold buttermilk, banana, and vanilla bean paste. Add buttermilk mixture to flour mixture, stirring with a fork until a shaggy dough forms.
Turn out dough onto a clean surface, and pat into a 1-inch-thick rectangle (about 7½×5 inches). (Dough will start out crumbly but will come together.) Cut dough crosswise into thirds. Stack thirds on top of each other; roll or pat to 1-inch thickness, and carefully flour underneath dough. Using a 2½-inch round cutter dipped in flour, cut dough without twisting cutter, rerolling scraps as necessary. Place ½ inch apart on prepared pan. Freeze until cold, about 15 minutes
Using a pastry brush, brush egg on top of dough.
Bake until golden brown, 15 to 20 minutes. Serve warm with softened butter
