Buying Cupcake Pans
Unlike muffins, cupcakes aren't usually made in jumbo sizes. When you buy cupcake pans for most recipes, look for basic cupcake pans with 12 wells, unless the recipe tells you to use larger ones. Avoid buying any pans that say “"jumbo"” if you are going to use them to make cupcakes from standard recipes. Cupcake pans can be found in most grocery stores and at discount stores.
Using Cupcake Liners
You can decide to use paper cupcake liners or not to use them. Unless seeing the bottom of the cupcake is important in the presentation of the dessert, I suggest that you use cupcake liners, even if you are using non-stick cupcake pans. While you can certainly butter and flour each of the wells in the pan, the little cakes might still sometimes stick. It's also just plain easier to use the liners. And they also help to keep the cupcakes fresh. They aren't expensive, and you can find them in the baking aisle of any grocery store.
Filling Cupcake Pans
It's really tempting to fill the cupcake wells almost up to the top, hoping to have high-rising cupcakes, but all you will get is a nasty mess of batter that overflows the wells and produces really ugly cupcakes. Don't confuse cupcakes with muffins; cupcakes should be just slightly rounded on the tops, while muffins have a more pronounced dome. So, unless a recipe tells you to fill the cupcake wells higher, fill the wells 1/2 to 2/3 full. The easiest way to gauge how much batter is needed for each cupcake is to use a standard size cupcake pan (unless the recipe specifies otherwise) and make exactly the number of cupcakes that the recipe tells you it should make.
Dipping Cupcakes in Ganache
One of the easiest and, to my palate, tastiest ways to frost a cupcake is to dip it in warm Chocolate Ganache. The Ganache forms a smooth, glossy coating over the surface of the cupcake. It’s lovely. And you can decorate the Ganache coating with sprinkles, coconut, or many other things, to make it look fun and festive.
To coat a cupcake with Ganache, turn the cupcake upside down and dip it into a bowl of warm Ganache. (The Ganache can be freshly made, or it can be made ahead and warmed so it is thin enough to coat the cupcake top.) Note that the Ganache will thicken as it cools, so if the coating is too thin for your tastes, just let the Ganache cool slightly and then try dipping another cupcake. Once they are dipped, turn the cupcakes upright and let them sit uncovered, at room temperature, until the Ganache firms up. Try not to eat all of the cupcakes as you coat them – it will be hard not to!
Coating Upside-Down Cupcakes with Ganache
The shiny, deep, dark chocolate coating that you see on some fancy cupcakes in upscale bakeries is actually very easy to accomplish in a home kitchen. Bake a batch of cupcakes without using cupcake liners: spray the cupcake wells generously with a non-stick spray and flour them, turning the pans upside down and tapping out any excess flour. Bake the cupcakes as directed in the recipe, setting the pans on a wire rack to cool for 5 minutes after baking. Then loosen the cupcakes gently with a kitchen knife or small spatula, and turn the pans over, so the cupcakes fall out. Set the cupcakes upright on the wire racks and cool them thoroughly before proceeding.
Make a batch of Chocolate Ganache, stirring until it is perfectly smooth. Set one large or two smaller wire cooling racks on a piece of wax paper or parchment. Brush any crumbs from the bottom and sides and place each of the completely cooled cupcakes upside-down on the wire racks, trimming a bit off them if necessary so the cupcakes sit flat. Slowly pour the slightly warm ganache over a cupcake, using a small spatula to guide it so it completely covers the bottom (which is now the top) and sides of the cupcake. Allow any extra to drip onto the parchment so it can be reused. Repeat with all of the cupcakes, and let them sit, at room temperature, until the ganache is firm to the touch. Then place them in an airtight container and keep them in a cool place until you serve them.
Freezing Cupcakes
You can make cupcakes in advance and freeze them frosted or unfrosted, although I prefer to frost them after they thaw. Either way, place them in a single layer in a plastic container just large enough to hold them, making sure the tops of the cupcakes don’t touch the top of the container, seal the container so it is airtight, and place it in your freezer. The day they are to be eaten, remove the container from the freezer and leave it, uncovered, at room temperature for 30 minutes. Frost them once they have defrosted. You can freeze cupcakes for up to two months.
Flavoring Cake Batter
It's effortless to change the flavor of basic cake batter. You can add a teaspoon or so of your favorite spice, or a combination of spices; a teaspoon or two of lemon zest with the juice of half a lemon; the zest of one orange and 1/4 teaspoon of pure orange flavoring; a half cupful of ground nuts; a few tablespoonfuls of grated chocolate, which will leave lovely flecks of chocolate throughout the batter; crushed malted milk balls; or finely chopped dried fruits. Add the spices, or zests and juice or flavoring with the butter. Any solid ingredients should be tossed with the flour before adding it to the batter.
