Creating Grape Soda Cupcakes is a fun and straightforward process. Follow these steps to bake your delightful treats:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Prepare a cupcake tin with liners.

2. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking powder, and salt until well combined.

3. Cream Butter and Sugar: In another bowl, beat the softened butter until creamy. Gradually add in the sugar and mix until fluffy.

4. Combine Wet Ingredients: Add the eggs, grape soda, and vanilla extract to the butter mixture. Mix until everything is well incorporated.

5. Combine Mixtures: Gradually add the dry ingredient mixture to the wet ingredients. Stir until just combined; do not overmix.

6. Optional Coloring: If desired, add a few drops of food coloring to enhance the purple shade of the batter. Mix gently to combine.

7. Bake: Pour the batter into the prepared cupcake liners, filling them about 2/3 of the way full. Bake in the preheated oven for 15-20 minutes or until a toothpick inserted into the center comes out clean.

8. Cool: Remove the cupcakes from the oven and let them cool in the pan for 5 minutes. Then, transfer them to a wire rack to cool completely.

9. Frost and Decorate: Once cooled, frost the cupcakes with your choice of frosting. Add sprinkles on top for an extra fun touch.
