Step-by-Step Method

Preheat & Prepare Pan

Preheat your oven to 350°F (175°C). Line a standard 12-cup muffin pan with paper cupcake liners so the cupcakes release easily and keep their shape.

Set out your butter, eggs, milk, and sour cream to come to room temperature. Gather all equipment and ingredients before starting to streamline the process.

Combine Dry Ingredients

Measure and sift the all-purpose flour into a medium bowl. Add the baking powder and fine salt. Whisk the mixture until everything is evenly combined and no streaks remain. Set this bowl aside.

Properly blending dry ingredients helps guarantee the cupcakes rise evenly and have a light, uniform texture throughout.

Cream Butter & Sugar

Place the softened unsalted butter in a large mixing bowl. Add the granulated sugar. Beat with an electric mixer on medium speed for 2–3 minutes.

Mix until the mixture is very light, pale, and fluffy. This step incorporates air, which helps create a tender, moist cupcake crumb while also improving overall structure.

Beat In Eggs

Crack the eggs into a small bowl to check for shells. Add one egg at a time to the butter-sugar mixture. Beat well after each addition until completely incorporated and smooth.

Scrape down the sides of the bowl with a rubber spatula as needed. This ensures an even batter without streaks of unincorporated egg.

Add Lemon & Vanilla

Add the finely grated lemon zest, fresh lemon juice, and vanilla extract to the bowl. Beat just until everything is thoroughly combined and fragrant.

The batter may look slightly curdled at this point; that’s normal due to the acidity from the lemon juice interacting with the fats and liquids in the mixture.

Mix Milk & Sour Cream

In a small bowl, combine the whole milk and sour cream. Stir until the mixture is smooth and uniform with no lumps.

Using both milk and sour cream adds richness and moisture. It also helps create a tender crumb and balances the bright lemon flavor with a subtle tang and extra softness.

Alternate Dry & Wet Additions

Add one-third of the dry ingredient mixture to the wet ingredients. Mix on low just until combined. Add half of the milk–sour cream mixture and mix gently.

Repeat with another third of the dry ingredients, the remaining milk mixture, then the final third of the dry mixture. Avoid overmixing to keep the cupcakes tender.

Fill Cupcake Liners

Use a measuring cup or scoop to divide the batter evenly among the 12 prepared liners. Fill each liner about two-thirds full so there’s room for the cupcakes to rise without overflowing.

Gently smooth the tops if needed. Even filling ensures consistent baking time and uniform cupcake size.

Bake Until Just Set

Place the muffin pan in the preheated oven. Bake for 16–18 minutes. Check for doneness by lightly pressing the tops; they should spring back.

Insert a toothpick into the center of a cupcake; it should come out clean or with a few moist crumbs. Avoid overbaking, which can dry out the cupcakes.

Prepare Lemon Syrup

While the cupcakes bake, combine fresh lemon juice and granulated sugar in a small saucepan. Heat over low, stirring constantly until the sugar fully dissolves and the mixture turns clear.

Remove from heat and let cool slightly. This lemon syrup will soak into the warm cupcakes, adding extra moisture and bright lemon flavor.

Soak Warm Cupcakes

Remove the cupcakes from the oven and let them cool in the pan for 5 minutes. While still warm, poke 4–5 small holes in each cupcake using a toothpick.

Spoon a little lemon syrup over each cupcake, letting it soak into the holes. This step infuses intense lemon flavor and keeps the cupcakes moist inside.

Cool Completely

Carefully transfer the cupcakes to a wire cooling rack. Allow them to cool completely, about 25 minutes.

Cooling on a rack lets air circulate all around, preventing soggy bottoms. Guarantee the cupcakes are fully cool before frosting so the buttercream doesn’t melt and slide off the tops.

Beat Butter for Frosting

Place the softened butter for the frosting into a medium mixing bowl. Beat with an electric mixer for about 1 minute, until the butter is smooth, creamy, and slightly lighter in color.

Properly creaming the butter creates a fluffy base that blends well with powdered sugar for a smooth, stable frosting.

Add Sugar & Flavorings

Gradually add the sifted powdered sugar to the butter, mixing on low at first to avoid dust. Increase to medium once mostly incorporated. Beat until thick and smooth.

Add the lemon juice, lemon zest, and a pinch of fine salt. Mix until the frosting is well flavored, smooth, and evenly combined throughout.

Adjust Consistency

Add heavy cream or milk to the frosting, 1 teaspoon at a time. Beat after each addition until the frosting becomes fluffy and spreadable.

Stop adding liquid once the texture is soft enough to pipe yet firm enough to hold its shape. Adjust with a little more powdered sugar if it becomes too thin.

Frost & Finish Cupcakes

Ensure the cupcakes are completely cool. Transfer the lemon frosting to a piping bag fitted with your favorite tip, or use an offset spatula. Frost generously, starting from the outer edge and swirling toward the center.

Serve immediately or store covered at cool room temperature, bringing to room temperature before serving if chilled.

Ingredient Swaps

• Use salted butter instead of unsalted and omit the added salt.
• Swap sour cream with plain Greek yogurt, or use buttermilk in place of both the milk and sour cream (same total volume).
• For dairy-free cupcakes, use a neutral oil or vegan butter and a plant-based milk plus vegan yogurt.
• Replace eggs with 1/4 cup unsweetened applesauce or 3 tablespoons aquafaba per egg for an egg-free version.
• If fresh lemons aren’t available, use bottled lemon juice plus a bit of lemon extract for brightness.

You Must Know

– Scale • For 24 cupcakes, multiply every ingredient by 2 and use 2 pans on the center rack, rotating halfway through the 16–18 minute bake window so they cook evenly front-to-back and side-to-side.

Serving Tips

• Top with fresh berries and a small mint sprig for color and freshness.
• Serve on a white platter with thin lemon slices scattered around for contrast.
• Pair with hot tea, iced tea, or sparkling water with lemon wedges.
• Add a dusting of powdered sugar over the frosting right before serving.
• Present in colorful cupcake wrappers that match a party or seasonal theme.

Storage & Make-Ahead

Store frosted cupcakes in an airtight container in the fridge for up to 4 days.

Bring to room temperature before serving for best texture.

Unfrosted cupcakes freeze well (tightly wrapped) for up to 2 months.

Thaw overnight in the fridge, then frost fresh the day you plan to serve.

Reheating

Reheat cupcakes gently: microwave 5–10 seconds (unwrapped) just until slightly warm.

Or warm in a 300°F (150°C) oven for 5–8 minutes, loosely tented with foil; avoid stovetop reheating.

Frequently Asked Questions

Can I Make These Lemon Cupcakes Gluten-Free, and Which Flours Work Best?

Yes, you can. I’d use a good 1:1 gluten-free baking blend with xanthan gum. I wouldn’t pick straight almond or coconut flour—too dense. Mix gently, let the batter rest, and you’ll keep that tender, sunny crumb.

How Can I Adapt This Recipe for High-Altitude Baking Conditions?

I’d adjust for your high altitude by reducing baking powder slightly, adding 1–2 tablespoons extra liquid, increasing oven temp 15–25°F, and shortening bake time a few minutes so the crumb stays tender and airy.

What’s the Best Way to Ship These Cupcakes Without Ruining the Frosting?

I’d chill them overnight, then nestle each frosted cupcake in a snug cupcake insert, inside a sturdy box. I’d pack gel packs, cushion every gap, mark “This Side Up,” and ship express-only.

Can I Turn This Cupcake Recipe Into a Full-Sized Layer Cake?

Yes, you can. I’d double the batter, bake it in two 8-inch pans at 350°F, and start checking at 22 minutes. Brush layers with syrup, then cloak everything in that velvety lemon frosting.

How Do I Scale This Recipe for a Large Party or Wedding?

I’d triple the recipe, bake it in batches, and plan two cupcakes per guest. I’d store cooled cupcakes airtight, unfrosted, then frost day-of; for weddings, I’d test a small batch first to confirm timing.
