Simple Cooking

Made with mascarpone cheese, this frosting is similar to cream-cheese frosting, but with a slightly richer flavor.

Ethereal mascarpone frosting blankets sponge cake in this adaptation of a famous Italian dessert. Extra yolks in the batter make the cake sturdy enough to hold a generous dose of coffee-liqueur syrup without becoming too soggy. Freshly brewed coffee or espresso would be a natural accompaniment, as would little glasses of marsala, a fortified Italian wine used in the soaking syrup.

This rich, thick chocolate glaze may remind you of hot fudge sauce in its flavor and consistency. Avoid overmixing when stirring the chocolate into the hot-cream mixture, as this can cause the ganache to become dull and grainy. To make a thinner glaze for coating the handwritten valentine cupcakes on page 212, see variation below.

Ganache—a smooth mixture of chocolate and cream—is one of the richest, most luscious of all chocolate frostings. The frosting is made in the same manner as the chocolate ganache glaze (opposite), and then allowed to thicken until the frosting is spreadable. Achieving the perfect consistency can be tricky; if the frosting becomes too firm to spread, reheat in a bowl over a pan of simmering water until it begins to melt around the edges, then remove from heat and stir until smooth.

Using meringue powder (or powdered egg whites), instead of raw egg whites, eliminates food-safety concerns. Look for the powder at baking-supply stores and many supermarkets. Royal icing hardens quickly, so if not using immediately, transfer to an airtight container and store in the refrigerator, up to one week; before using, stir with a flexible spatula until smooth.

Follow this recipe to make a glaze with any citrus flavor, such as orange, lemon, or lime.

Contrary to its name, pastry cream—a classic custard filling for cakes, tarts, pastries, and other baked goods—contains no cream, only milk. Be sure to bring the mixture to a full boil to activate the cornstarch and ensure proper thickening.

This familiar dessert topping makes a versatile last-minute embellishment for cupcakes. It can be dolloped on top as an alternative to heavier frostings, or used as a filling for split cupcakes. Whether you use a handheld whisk or an electric mixer to whip the cream, be sure not to overmix, or the consistency can become grainy. For unsweetened whipped cream, simply omit the sugar.

You will likely make these cupcakes again and again, varying the frosting (say, dark chocolate, page 302) and sprinkles (sparkly, multicolored, or otherwise) to suit your whim or fancy. Two types of flour contribute to the cupcakes’ singular texture: Cake flour makes for a delicate crumb, while all-purpose flour keeps them from being too tender.

Fanciful peaks in a spectrum of shades crown cupcakes with a motif inspired by a vintage Russian cookbook. You could also opt to use just one color of frosting, or leave it untinted. White cupcakes, made with egg whites only (instead of whole eggs), are very light and delicate. For a stronger vanilla flavor, scrape the seeds of one vanilla bean (halved lengthwise) into the milk in step one, and omit vanilla extract.

Buttery and crunchy, sugar cookies are delicious on their own and make delightful cupcake toppers when decorated with royal icing. This dough is a favorite of Martha Stewart Living food editors for its flavor and texture, which is just right for rolling out and cutting into shapes. Follow the recipe below to make your own designs, or cut and bake as directed in specific cupcake recipes.

This recipe is used to make the brownie hearts on page 213; some of the batter is baked in muffin tins, the rest in an 8-inch pan for cutting into heart-shaped toppers.
