Plum Buckle for Two

Preheat the oven to 350°F. Butter and flour a 6” round cake pan.

In a small bowl, combine all streusel ingredients (except butter). Then, with your fingertips, smear the butter into the streusel.

Next, pit the plum and dice it into a medium dice (leaving the skin on). In a small bowl, stir together the flour, baking powder and salt. In a medium bowl, stir together with a wooden spoon the softened butter and sugar. Add the egg white and vanilla. Use at least 30 strokes to bring this mixture together. To the creamed mixture, add half of the dry ingredients, followed by half of the buttermilk. Add the remaining dry ingredients followed by the rest of the buttermilk. Stir in the diced plums gently. Scrape the batter into the pan and spread it to the edges with a spatula. Note: it might seem dry but it’s fine. Sprinkle the streusel evenly on top of the batter.

Bake for 38-45 minutes, until a toothpick inserted comes out clean.
