Follow these simple steps to create your Grape Soda Cupcakes With Creamy Frosting:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a cupcake tin with paper liners.
2. Mix Dry Ingredients: In a large bowl, sift together the flour, granulated sugar, cocoa powder, baking powder, and salt until well combined.
3. Combine Wet Ingredients: In another bowl, whisk together the grape soda, vegetable oil, eggs, and vanilla extract until smooth.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring until the batter is smooth and well combined.
5. Fill Cupcake Liners: Pour the batter evenly into the prepared cupcake liners, filling each about two-thirds full.
6. Bake: Place in the preheated oven and bake for 18-20 minutes or until a toothpick inserted in the center comes out clean.
7. Cool: Remove from the oven and let the cupcakes cool in the tin for 5 minutes. Then transfer them to a wire rack to cool completely.
8. Prepare the Frosting: In a large bowl, whip the heavy cream until soft peaks form. Gradually add powdered sugar and grape extract, continuing to whip until stiff peaks form.
9. Frost the Cupcakes: Once the cupcakes are completely cool, pipe or spread the creamy frosting on top of each cupcake.
10. Decorate: Add sprinkles or any grape-themed decorations to make them extra special.
