Blackberry Buttermilk Cake

• 3/4 cup (1 1/2 sticks) unsalted butter, room temperature, plus more for pan and parchment
• 2 1/3 cups cake flour (sifted, then measured) plus more for pan
• 2 1/2 cups (10 ounces) fresh blackberries
• 1/4 cup plus 1 1/3 cups sugar
• 1 1/2 teaspoons baking powder
• 3/4 teaspoon salt
• 1/2 teaspoon baking soda
• 3 large eggs, room temperature
• 2 teaspoons vanilla extract
• 1 1/2 teaspoons finely grated orange zest
• 1 cup well-shaken buttermilk
• Powdered sugar (for dusting)
• Use a 9"-10"-diameter springform pan.

1. Position a rack in middle of oven and preheat to 350u0b0. Butter pan; line bottom with a round of parchment paper. Butter parchment. Dust with flour; tap out excess. Arrange berries in a single layer in bottom of pan; sprinkle evenly with 1/4 cup sugar.
2. Sift 2 1/3 cups flour, baking powder, salt, and baking soda into a medium bowl; set aside. Using an electric mixer, beat 3/4 cup butter and remaining 1 1/3 cups sugar in a large bowl at medium-high speed, occasionally scraping down sides of bowl, until pale and fluffy, about 2 minutes. Add eggs, one at a time, beating well after each addition. Beat in vanilla and zest. Reduce speed to low; beat in flour mixture in 3 additions, alternating with buttermilk in 2 additions, beginning and ending with flour mixture and beating just until incorporated. Pour batter over berries in pan; smooth top.
3. Bake until cake is golden brown and a tester inserted into the center comes out clean, about 1 hour 25 minutes. Let cool in pan set on a wire rack for 15 minutes, then run a thin, sharp knife around edge of pan to loosen. Remove pan sides. Invert cake onto rack and remove pan bottom; peel off parchment. Dust top generously with powdered sugar and let cool completely.
