# Expert Tips:

01 -
  • The cupcakes stay incredibly moist because the grape soda creates steam while baking, almost like a tiny chemistry experiment happening inside each paper liner
  • Theyre the ultimate conversation starter at parties people literally light up when they realize what that familiar flavor is
02 -
  • Room temperature ingredients are absolutely crucial cold butter or eggs will cause your batter to seize and not incorporate properly
  • Let these cool completely before frosting or your buttercream will melt right off into a sad purple puddle
03 -
  • Use an ice cream scoop to fill your cupcake liners for perfectly uniform portions every time
  • Tap the filled muffin tin gently on the counter once to release any air bubbles before baking
