Forgetting to get creative with boxed mix
Even if it's been said that baking is a science, you may still employ your imagination! You have lots of options to avoid preparing dull, tasteless treats as there are dozens of entertaining cupcake recipes available with just a short online search. There are amazing baking techniques to make pre-packaged desserts taste like a pastry chef's masterpiece, even if you're limited to using a boxed cake mix and a jar of frosting from the grocery store. Your cupcakes will taste better if you replace a variety of the components in packaged cake mixes. For thicker, more luxurious cupcakes, you can experiment with replacing the water with dairy milk and the oil with melted butter.
Similarly, you may be very inventive and add a spoonful or two of mayonnaise to the mixture for "extra-moist cake" or experiment with using hot water (rather than room temperature) to make chocolate cake mix even more chocolaty. You can still be inventive even if you're using a handmade recipe rather than one from a box! When your cupcakes are finished baking and cooling, try taking a little piece out of the middle and filling it with your own frosting, sprinkles, or your favorite mini-candy to experience a delicious surprise with each mouthful.
