Cupcake Queens Williamstown: A Bakery-Style Vanilla Cupcake

“Cupcake Queens Williamstown” points to a cupcake-shop style treat: a soft vanilla cupcake topped with a generous swirl of buttercream. This reliable home-baking version uses everyday ingredients, makes a dozen cupcakes, and works for birthdays, afternoon tea, or any time you want a classic bakery look.

Ingredients

1½ cups (190 g) all-purpose flour, spooned into the cup and leveled
1½ teaspoons baking powder
¼ teaspoon fine salt
½ cup (113 g) unsalted butter, softened
¾ cup (150 g) granulated sugar
2 large eggs, at room temperature
2 teaspoons vanilla extract
½ cup (120 ml) whole milk, at room temperature
1½ cups (180 g) powdered sugar, sifted if lumpy
1 tablespoon (15 ml) heavy cream or milk, plus up to 1 tablespoon (15 ml) more as needed
Pinch of fine salt, for the buttercream
Sprinkles, optional, for decorating

Instructions

Set a rack in the center of the oven and heat it to 350°F (175°C). Line a 12-cup muffin pan with paper liners. Let the butter, eggs, and milk come to room temperature so the batter combines evenly.
In a medium bowl, whisk together the flour, baking powder, and salt. In a larger bowl, beat the softened butter and granulated sugar with a hand mixer on medium speed for about 2–3 minutes, until pale and fluffy. Scrape down the bowl once during mixing.
Beat in the eggs one at a time, mixing just until each is incorporated. Add the vanilla. If the mixture looks slightly curdled, continue with the recipe; it should come together when the dry ingredients and milk are added.
Add about one-third of the flour mixture and mix on low just until it disappears. Mix in half the milk, then another third of the flour, the remaining milk, and the remaining flour. Stop as soon as no dry streaks remain; overmixing can make the cupcakes dense.
Divide the batter evenly among the liners, filling each about two-thirds full. Bake for 17–19 minutes, until the tops spring back lightly when touched and a toothpick inserted in the center comes out clean or with a few dry crumbs. Avoid opening the oven in the first 15 minutes, which can make the cupcakes sink.
Cool the cupcakes in the pan for 5 minutes, then transfer them to a wire rack and let them cool completely, about 30 minutes. Do not frost warm cupcakes: the buttercream will soften and slide off.
For the buttercream, beat the softened butter in a clean bowl on medium speed for about 2 minutes, until smooth. Add the powdered sugar in two additions, mixing on low at first to prevent a sugar cloud, then beat in the cream, vanilla, and a pinch of salt. Beat for 1–2 minutes until fluffy. Add more cream a teaspoon at a time if it is too stiff; add a little more powdered sugar if it is too loose.
Spread or pipe the buttercream onto the fully cooled cupcakes. Finish with sprinkles if desired. For a bakery-style swirl, use a piping bag fitted with a large open-star tip, starting at the outside edge and spiraling inward.

Tips

Measure flour by weight when possible. If using cups, fluff the flour, spoon it into the measuring cup, and level the top; scooping directly can add too much and dry out the crumb.
Room-temperature ingredients blend more smoothly. If you forgot to soften the butter, cut it into small pieces and leave it out briefly; do not melt it, since melted butter changes the cupcake texture.
For a dairy-free version, use an unsweetened, unflavored plant milk and a baking stick formulated for buttercream. The frosting may taste slightly different and its firmness can vary by brand.
For neat frosting, make sure cupcakes are completely cool and keep the buttercream soft but able to hold its shape. If it becomes greasy or too soft, chill it for 10 minutes, then beat briefly again.

Serving Suggestions

Serve the cupcakes at room temperature so the cake is tender and the buttercream is easy to bite. Arrange them on a platter for a party, or serve individually with coffee, tea, or a glass of milk. For a simple finish, use a small amount of sprinkles; for a more polished display, pipe the frosting shortly before serving and add decorations while it is still soft.

If making them ahead for an event, keep the cupcakes covered and away from heat or direct sunlight. Set them out shortly before serving if they have been refrigerated, since cold cake and frosting feel firmer and less fragrant.

Variations

Chocolate: Replace ¼ cup (30 g) of the flour with ¼ cup (21 g) unsweetened cocoa powder. The chocolate flavor will be mild; for a richer result, use chocolate buttercream rather than adding extra cocoa to the batter.
Lemon: Add 1 tablespoon (6 g) finely grated lemon zest to the butter and sugar before creaming. Replace 1 teaspoon of the vanilla with lemon juice, keeping the total liquid close to the original amount.
Filled cupcakes: Once cool, remove a small cone from the center of each cupcake and add about 1 teaspoon (5 ml) of jam or lemon curd. Replace the cake plug loosely or leave the filling visible, then frost.
Confetti: Fold ¼ cup (40 g) of rainbow jimmies into the finished batter with a spatula. Avoid nonpareils, which can bleed color into the batter.

Storage and Reheating

Because the frosting contains butter and cream, refrigerate frosted cupcakes within 2 hours. Store them in a single layer in an airtight container for up to 3 days. Let them stand at room temperature for about 30–45 minutes before serving for a softer crumb and frosting. Do not microwave frosted cupcakes; the buttercream can melt unevenly.

Unfrosted cupcakes can be kept in an airtight container at room temperature for up to 2 days, or frozen for up to 2 months. To freeze, cool completely, wrap each cupcake well, and place in a freezer-safe container. Thaw wrapped cupcakes at room temperature, then frost. Buttercream can be refrigerated in an airtight container for up to 5 days or frozen for up to 2 months; bring it to room temperature and beat briefly before using. Discard cupcakes left at room temperature for more than 2 hours.

Frequently Asked Questions

Can I make these cupcakes without a mixer?
Yes. Use a sturdy whisk and a flexible spatula, and make sure the butter is very soft but not melted. Cream the butter and sugar thoroughly by hand, then mix the eggs in one at a time. Fold in the flour and milk gently to avoid overworking the batter.

Why did my cupcakes sink in the middle?
Common causes include opening the oven too early, underbaking, overmixing, or using too much baking powder. Check that your baking powder is fresh and test doneness near the center of a cupcake. Avoid moving the pan until the tops are set.

Can I bake the batter as a cake?
This amount is suited to 12 standard cupcakes. For a small cake, divide the batter between two greased and parchment-lined 6-inch (15 cm) round pans, and begin checking after about 22 minutes; exact timing depends on the pan and oven. Bake until the center springs back and a tester comes out clean.

Can I prepare the batter ahead?
It is best to bake the batter shortly after mixing because the baking powder starts working once it is moistened. For easier advance preparation, bake and cool the cupcakes a day ahead, then store them covered and frost before serving.

How do I keep the frosting from being too sweet?
Use the pinch of salt in the recipe, and add cream gradually until the texture is smooth. You can reduce the powdered sugar slightly, but the buttercream will be softer and less able to hold a tall piped swirl. A thin layer of frosting is another easy way to balance sweetness.

Can I use salted butter?
Yes. Omit the salt from the cupcake batter and leave only a very small pinch, or none, in the buttercream. Salt levels vary by brand, so taste the frosting before adding any additional salt.
