Notes
Tips on baking the best cupcakes:
Follow the recipe. Sounds obvious, right? I am the biggest substite-er when it comes to recipes, if I don't have one thing I quick google a substitute. But with baking I've found that it's more of a science that needs to be followed. If you wish to switch out ingredients, I recommend first making the recipe as it is, and next time make alterations as you see fit. That way if they don't turn out you'll know if it's the recipe or the alteration.
Use room temperature ingredients. This isn't just pasted next to ingredients for fun. Room temperature ingredients bond together much easier since they're warmer, creating a seamless and evenly textured batter. Cold ingredients just don't incorporate as well. This results in clumpy frosting, and sometimes flat cupcakes.
Don't under-mix, don't over-mix. Make sure you're just mixing the batter until the dry and wet ingredients are combined. Overmixing batter results in a tough-textured cupcake. And obviously, we don't want to undermix the cupcake batter.
How to store:
These cupcakes will keep in the fridge for 5 days. Store them in an airtight container. They also freeze perfectly. Just make sure to thaw them in the fridge, otherwise the buttercream sweats and it will have droplets of moisture.
