Frequently Asked Questions
- Can I use diet grape soda?

The grape soda adds a subtle fruity flavor that’s sweet and nostalgic, without being overpowering. - Can I use a different flavor of soda?
Yes! This recipe also works great with orange, lemon-lime, or strawberry soda. - Do I need food coloring?
Nope! It’s just for added color. The cupcakes will still taste amazing without it.
