Creating Grape Soda Cupcakes is simple if you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until well combined.
3. Cream Butter and Sugar: In another bowl, cream the softened butter with the granulated sugar until light and fluffy.
4. Add Eggs and Vanilla: Beat in the eggs, one at a time, followed by the vanilla extract, mixing well after each addition.
5. Combine Wet and Dry Ingredients: Gradually add the dry ingredients to the butter mixture, alternating with the grape soda and milk. Mix until just combined; do not overmix.
6. Fill Cupcake Liners: Spoon the batter into the prepared cupcake liners, filling each about two-thirds full.
7. Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes or until a toothpick inserted in the center comes out clean.
8. Cool: Once baked, remove the cupcakes from the oven and allow them to cool in the tin for 15 minutes. Then, transfer them to a wire rack to cool completely.
9. Frost: Once the cupcakes have cooled, frost them generously with purple frosting, ensuring each cupcake is covered.
10. Garnish: For an extra touch, sprinkle grape soda pop rocks on top of the frosting for a fun, fizzy effect.
