Mother-in-Law's Plum Bread

Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). \nTo prepare the loaf pan, spray it with cooking spray or cover it with parchment paper to prevent sticking. \nNext, mix 1 tablespoon of flour with chopped plums in a bowl and gently toss to coat them evenly; set the plum mixture aside for later use. \nIn a large mixing bowl, combine white sugar, butter, and vanilla extract, then beat them together using an electric mixer until they become light and fluffy. \nAdd eggs to the bowl one by one, beating them into the mixture until it's fully incorporated. \nIn a separate bowl, sift together 1 ½ cups of flour, salt, and baking soda. \nGradually add the dry ingredients to the egg mixture, alternating with yogurt until you achieve a smooth consistency. \nFold in the plum mixture that you had set aside earlier, making sure they're evenly distributed throughout the batter. \nPour the prepared batter into your loaf pan, making sure to cover the entire surface. \nSprinkle brown sugar evenly over the top of the batter in your loaf pan, adding a delightful texture to the final product. \nOnce you've prepared everything, bake the loaf in your preheated oven for 45 to 50 minutes, or until a toothpick inserted into the center comes out clean. \nRemove the loaf from the oven and let it cool in its pan for 15 minutes, allowing the heat to dissipate evenly. \nFinally, invert the loaf onto a wire rack and let it cool completely before serving.
