Follow these simple steps to make your Cherry Cobbler Muffins:

1. Preheat Oven: Preheat your oven to 375°F (190°C). Line a 12-cup muffin pan with paper liners or grease it lightly.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, baking soda, salt, and cinnamon.
3. Prepare Wet Ingredients: In another bowl, whisk the egg, then add the milk, melted butter, and vanilla extract. Mix until well combined.
4. Combine Mixtures: Pour the wet ingredients into the dry ingredients. Stir gently until just combined; do not overmix.
5. Add Cherries: Gently fold the halved cherries into the batter, ensuring they are evenly distributed.
6. Fill Muffin Cups: Divide the batter evenly among the prepared muffin cups, filling each about 2/3 full.
7. Top with Sugar: If desired, sprinkle coarse sugar on top of the batter for a sweet crunch.
8. Bake: Place the muffin pan in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
9. Cool: Remove from the oven and let the muffins cool in the pan for about 5 minutes. Then, transfer them to a wire rack to cool completely.
10. Enjoy: Serve warm or at room temperature, and enjoy the incredible flavors of your Cherry Cobbler Muffins!
