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.
Preheat oven to 350 degrees F (175 degrees C). Grease a 12 cup muffin pan or line with paper baking cups. In a large bowl, mix butter and sugar with an electric mixer until light and fluffy, about 5 minutes. Stir in the eggs, one at a time, blending well after each one. Stir in the vanilla and flour just until mixed. Spoon the batter into the prepared cups, dividing evenly. Bake in the preheated oven until the tops spring back when lightly pressed, 18 to 20 minutes. Cool in the pan set over a wire rack. When cool, arrange the cupcakes on a serving platter.
