Making Blackberry Dumplings can be straightforward. Just follow these steps to create this incredible dessert:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C).
2. Prepare the Blackberries: In a medium bowl, gently toss the blackberries with half of the granulated sugar (½ cup). Allow them to sit for about 10 minutes to release their juice.
3. Mix Dry Ingredients: In another bowl, whisk together the flour, baking powder, salt, and cinnamon (if using).
4. Combine Wet Ingredients: In a separate bowl, combine the milk, melted butter, remaining sugar (½ cup), and vanilla extract. Mix until well combined.
5. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring until just combined. Avoid overmixing; a few lumps are okay.
6. Prepare Baking Dish: Grease a baking dish (9×9 inch works well) with butter or cooking spray, and spread the blackberries evenly on the bottom.
7. Add Dumpling Batter: Pour the batter over the blackberries. Do not stir; the batter will rise as it bakes, creating a dumpling-like texture.
8. Bake: Place the baking dish in the preheated oven and bake for 25 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
9. Cool: Once baked, remove from oven, and let it cool for a few minutes before serving. This cooling step allows the flavors to meld beautifully.

Creating Blackberry Dumplings is simple, and following these steps will ensure success every time!
