- 1/4 cup all-purpose flour
- 1/4 teaspoon salt
- 1 1/3 cups well-shaken buttermilk
- 1/2 stick butter, melted and cooled
- 3 large eggs, separated
- 2/3 cup sugar, divided
- 2 half-pints raspberries (1/2 pound)
- 1/3 cup pure maple syrup
- Preheat oven to 350°F with rack in middle. Butter a 1 1/2-quart shallow baking dish.
- Whisk together flour and salt in a large bowl. Whisk together buttermilk, butter, yolks, and 1/3 cup sugar in a separate bowl, then stir into flour mixture.
- Beat egg whites with an electric mixer at medium speed until frothy. Increase speed to medium-high and add remaining 1/3 cup sugar, 1 tablespoon at a time, beating until whites just hold stiff peaks.
- Stir about one third of whites into batter to lighten, then fold in remaining whites gently but thoroughly. Pour batter into baking dish and bake in a water bath until puffed and golden-brown, 40 to 50 minutes. Cool slightly, 10 to 15 minutes.
- Toss raspberries with maple syrup and serve with warm pudding cake.
