Mini cupcakes take about 2/3 of the time to bake compared to regular cupcakes. For example, if you have a regular-sized cupcake recipe that says it takes 21 minutes to bake, it will take only about 14 minutes for mini cupcakes, give or take 1-2 minutes. Mini cupcakes take about 1/2 the time to bake compared to a recipe for a 9Ã13 (quarter sheet) cake. For example, if you have a 9Ã13 cake that takes 30-35 minutes to bake, take the smaller number and divide it by 2.
