Notes
• No buttermilk? Add a squeeze of lemon and let sit for 2 minutes. Milk will curdle.
• Bananas not ready? Can’t do without this coffee cake? Roast bananas. Adjust oven rack to upper middle position and heat oven to 325°. Place 3 unpeeled, (bright yellow) bananas on a baking sheet. Bake until skins are completely black, about 20 minutes. Let cool for 5 min.
