Cupcake Mafia Leroy MI: A Bakery-Style Cupcake Recipe

“Cupcake Mafia Leroy MI” points to Cupcake Mafia, a bakery in Leroy, Michigan, rather than to a recognized regional cupcake recipe. This home-style vanilla cupcake recipe makes tender, buttery cakes with a simple vanilla buttercream, using standard baking ingredients and clear steps for a reliable batch.

Ingredients

  • 1½ cups (190 g) all-purpose flour, spooned into the measuring cup and leveled
  • 1½ teaspoons (6 g) baking powder
  • ¼ teaspoon (1.5 g) fine salt
  • ½ cup (113 g) unsalted butter, softened
  • ¾ cup (150 g) granulated sugar
  • 2 large eggs (about 100 g without shells), at room temperature
  • 2 teaspoons (10 ml) vanilla extract
  • ½ cup (120 ml) whole milk, at room temperature
  • 1 cup (113 g) unsalted butter, softened, for frosting
  • 3 cups (360 g) powdered sugar, sifted if lumpy
  • 2 tablespoons (30 ml) whole milk or cream, plus more as needed
  • 1 teaspoon (5 ml) vanilla extract, for frosting
  • ⅛ teaspoon (0.75 g) fine salt, for frosting
  • Sprinkles, optional: 2 tablespoons (about 20 g)

Instructions

  1. Set the butter, eggs, and milk out about 30 minutes before baking so they are not refrigerator-cold. Heat the oven to 350°F (175°C). Line a 12-cup muffin pan with paper liners. This recipe makes 12 standard cupcakes.
  2. Whisk the flour, baking powder, and salt together in a medium bowl. In a separate large bowl, beat ½ cup (113 g) softened butter with the granulated sugar for 2–3 minutes, until pale and fluffy. A hand mixer or stand mixer with the paddle attachment works well; scrape the bowl once.
  3. Beat in the eggs one at a time, mixing until incorporated after each. Mix in 2 teaspoons (10 ml) vanilla. If the mixture looks slightly curdled, continue; it should come together when the dry ingredients are added.
  4. Add about one-third of the flour mixture and mix on low just until mostly combined. Add half the milk, then another third of the flour, the remaining milk, and the remaining flour. Mix gently after each addition, stopping as soon as no dry streaks remain. Scrape the bowl and fold once or twice by hand; overmixing can make cupcakes tough.
  5. Divide the batter evenly among the liners, filling each about two-thirds full. Bake for 17–19 minutes, rotating the pan once if your oven heats unevenly. The tops should spring back lightly when touched, and a toothpick inserted in the center should come out with a few moist crumbs, not wet batter. Avoid relying on color alone.
  6. Cool the cupcakes in the pan for 5 minutes, then transfer them to a wire rack. Let them cool completely, about 30 minutes, before frosting. Frosting warm cupcakes will melt the buttercream.
  7. For the frosting, beat 1 cup (113 g) softened butter on medium speed for 2 minutes until smooth. Add the powdered sugar in three additions, mixing on low first to limit a cloud of sugar, then beat in 2 tablespoons (30 ml) milk or cream, 1 teaspoon (5 ml) vanilla, and ⅛ teaspoon (0.75 g) salt. Beat on medium-high for 1–2 minutes until fluffy. Add milk a teaspoon at a time if it is too stiff, or a little more powdered sugar if it is too loose.
  8. Spread or pipe frosting onto the cooled cupcakes. Add sprinkles while the frosting is still soft, if using. Serve at room temperature.

Tips

  • Measure flour lightly: spoon it into the cup and level the top rather than scooping directly from the bag. Too much flour can make the crumb dry and dense.
  • 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 for this creaming-style batter.
  • For a less sweet frosting, reduce the powdered sugar slightly, but expect a softer result that may not hold a tall piped swirl. Chill it for 10–15 minutes if it becomes too soft to pipe.
  • Do not frost until the cakes are fully cool. If the centers sink, common causes include opening the oven door early, overfilling liners, or underbaking; check one cupcake near the center of the pan before removing the batch.

Serving Suggestions

Serve these cupcakes as a simple birthday or party dessert, with coffee, tea, or a glass of milk. For a dessert table, arrange them with fruit and smaller treats so guests can choose a range of portions. If transporting them, use a cupcake carrier or a deep, rigid container so the frosting does not touch the lid.

Variations

For chocolate cupcakes, replace ¼ cup (30 g) of the flour with ¼ cup (20 g) unsweetened cocoa powder; the cocoa makes the cakes darker and less vanilla-forward. For a citrus note, add 1 teaspoon (about 2 g) finely grated lemon zest to the sugar before creaming the butter. You can also fold ½ cup (85 g) mini chocolate chips into the finished batter, though they may settle slightly.

To make a simple colored frosting, add a small amount of gel food coloring after the butter is beaten and before adding the sugar. Liquid coloring can loosen the frosting, so use it sparingly. For a filling, remove a small plug from each cooled cupcake, add about 1 teaspoon of thick jam, and replace the plug before frosting; avoid runny fillings, which can leak.

Storage and Reheating

Because the frosting contains butter and milk, refrigerate frosted cupcakes within 2 hours of serving. Keep them in a covered container for up to 3 days for best texture; they can be refrigerated for up to 4 days. Let refrigerated cupcakes sit at room temperature for 20–30 minutes before serving so the cake and frosting soften. Cupcakes are not usually reheated, since heat melts the frosting.

For longer storage, freeze unfrosted cupcakes in an airtight container for up to 2 months. Thaw them covered at room temperature, about 1–2 hours, then frost. Buttercream can be stored separately in the refrigerator for up to 4 days or frozen for up to 2 months; thaw and beat briefly until smooth before using. Do not leave perishable frosted cupcakes at room temperature for more than 2 hours, or more than 1 hour if the room is above 90°F (32°C).

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 soft enough to press easily. Creaming by hand takes more effort; beat until the mixture looks noticeably lighter, then mix the batter only until combined.

Can I use salted butter?
Yes. Omit the ¼ teaspoon salt in the cake and the ⅛ teaspoon in the frosting, then taste the frosting and add a small pinch only if needed. Salt levels vary among butter brands.

Why did my cupcakes turn out dry?
Too much flour, overmixing, or baking too long are the most common reasons. Weigh the flour when possible, stop mixing as soon as the batter is combined, and begin checking at 17 minutes because oven temperatures vary.

Can I make the batter ahead?
For the best rise, bake the batter soon after mixing, while the baking powder is active. You can bake the cupcakes a day ahead, cool them completely, and store them unfrosted in an airtight container before decorating.

Can I make mini cupcakes?
Yes. Divide the batter among lined mini-muffin wells, filling each about two-thirds full, and begin checking after 9–11 minutes. The exact time depends on the pan and oven; use the spring-back and toothpick cues rather than the standard-cupcake timing.

Do these cupcakes need to be refrigerated?
Frosted cupcakes should be refrigerated because the buttercream includes milk. Unfrosted cupcakes can stay covered at room temperature for up to 2 days, provided the room is cool; refrigerate or freeze them for longer storage.
