- 1 1/2 cups all-purpose flour
- 1 tsp. baking powder
- 1/4 tsp. salt
- 16 Tbs. (2 sticks) unsalted butter, at room
- 1 cup plus 1 Tbs. sugar
- 2 eggs, at room temperature
- 6 to 8 plums, about 1 lb. total, halved, pitted
and each half cut into 4 slices
- 1/4 tsp. ground cinnamon
In a bowl, whisk together the flour, baking powder and salt. Set aside.
In the bowl of an electric mixer fitted with the flat beater, beat together the butter and the 1 cup sugar until pale and fluffy. Add the eggs one at a time, beating well after each addition. Add the flour mixture and mix well.
Scrape the batter into the prepared pan and spread evenly. Poke the plum slices into the batter, placing them close together. In a small bowl, combine the cinnamon and the 1 Tbs. sugar and sprinkle over the surface.
Bake until the top is golden, the edges pull away from the pan, and a skewer or cake tester inserted into the center comes out clean, 50 to 60 minutes. Transfer the pan to a wire rack and let cool for about 30 minutes before serving. Serves 8.
Note: Another homey, old-fashioned dessert, a buckle is a dish in which cake batter is mixed with fruit, often blueberries, and then baked. It is frequently topped with a cinnamon streusel.
