A standard box of cake mix generally makes about 24 standard-sized cupcakes. This is based on the fact that a box of cake mix typically yields about 5 cups of batter, which is enough for 24 regular cupcakes when the cavities are filled about two-thirds full

. For mini cupcakes, one box of cake mix can make approximately 48 to 60 mini cupcakes, depending on the size of the mini cupcake liners and how full the cavities are filled

. Jumbo cupcakes are fewer in number, with a box making about 12 jumbo cupcakes

. In summary:

• Standard cupcakes per box: ~24
• Mini cupcakes per box: ~48 to 60
• Jumbo cupcakes per box: ~12

This range can vary slightly depending on the brand and recipe, but these are typical yields from a standard box cake mix.
