Decomposing waste materials in public and private sewer and septic systems create sewer gases. Methane is the largest single constituent of sewer gas, which includes an assortment of toxic and non-toxic gases, such as hydrogen sulfide, carbon dioxide, ammonia, nitrogen oxides, and sulfur dioxide.
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.
Reduce the bake time listed in your cake recipe to the correct amount of time based on the particular size of your muffin pan. You don't need an elaborate mathematical formula to convert bake times for a muffin pan. Instead of starting with the time listed in your recipe, use your pan size as a handy guide. Bake muffins or cupcakes in mini muffin pans for eight to 10 minutes. Place one heaping tablespoon of batter in the pan for each muffin. This size of a pan yields about five dozen muffins or cupcakes.
