Ingredients You’ll Need

You’ll be amazed at how a handful of simple, everyday ingredients bloom into something so vibrant and irresistible. Each item here plays a starring role: lemon for brightness, butter for richness, and sour cream for unbeatable tenderness. Gather these and get ready for cupcake success!

Lemon zest: Intensifies the citrusy perfume and infuses every crumb with fresh lemon flavor.
All-purpose flour: Forms the structure of your Lemon Cupcakes, creating a soft, sturdy base.
Granulated sugar: Sweetens and, when mixed with zest, amplifies the lemon aroma throughout.
Baking powder: Ensures the cupcakes rise tall and fluffy.
Baking soda: Helps balance acidity and add a little more lift.
Kosher salt: Brings out the other flavors and makes the sweetness shine.
Unsalted butter (melted for cakes, softened for frosting): Supplies a rich, moist crumb and creamy frosting.
Eggs (room temperature): Hold everything together, lend structure, and make the crumb tender.
Sour cream: Adds gorgeous moisture and a tangy depth that complements the lemon.
Whole milk (warm): Keeps your cupcakes super light and moist.
Fresh lemon juice: Adds intense citrus punch to both cake and buttercream.
Powdered sugar: Makes the buttercream silky and beautifully sweet.
Salt (for the buttercream): Balances out the sweetness and emboldens the lemon flavor in the frosting.

How to Make Lemon Cupcakes

Step 1: Prep and Preheat

Start by preheating your oven to 375°F (190°C) and lining a cupcake tin with paper liners. This step sets you up for success, ensuring your Lemon Cupcakes bake evenly and are easy to remove and share later on!

Step 2: Infuse the Sugar

Pulse your granulated sugar and fresh lemon zest together in a food processor until the sugar becomes pale yellow and smells like a lemon grove. This tiny step is a secret weapon for capturing every bit of lemon essence throughout your cupcakes.

Step 3: Mix Dry Ingredients

Sift together flour, baking powder, baking soda, and salt in a big mixing bowl. Whisk to fully combine. This guarantees that each cupcake gets the perfect rise and a tender crumb.

Step 4: Blend Wet Ingredients

In a separate bowl, whisk eggs, warm milk, melted butter, fresh lemon juice, sour cream, and your fragrant lemon sugar. Make sure everything is at room temperature—this ensures a smooth batter without lumps. If you do spot any little clumps, a quick zap in the microwave (30 seconds, then a stir) does the trick!

Step 5: Combine Batter

Pour the wet mixture gently into the dry ingredients, stirring until just incorporated. Avoid overmixing to keep the cupcakes feather-light. The batter will look creamy and smell heavenly at this point!

Step 6: Bake to Perfection

Fill the cupcake liners three-quarters full. Bake for five minutes at 375°F, then lower the temperature to 350°F and bake another 10–12 minutes. They’re done when the tops bounce back gently to your touch and a toothpick comes out mostly clean. Allow them to cool—patience pays off here as the flavors settle in beautifully!

Step 7: Prepare Lemon Buttercream

Beat together softened butter, lemon zest, and salt until the mixture turns pale and fluffy. Gradually add the powdered sugar, mixing well after each addition. Drizzle in the fresh lemon juice while beating on low, scrape down the bowl, and whip until the frosting is luscious and creamy.

Step 8: Decorate with Style

Once the cupcakes are completely cool, slather or pipe on your lemon buttercream as fancifully as you like! From rustic swirls to elegant peaks, this is your chance to get creative with your Lemon Cupcakes.

How to Serve Lemon Cupcakes

Garnishes

Dress up your Lemon Cupcakes with a sprinkle of extra lemon zest, candied lemon slices, or even fresh edible flowers for a stunning, sunny finish. A few poppy seeds add a playful crunch and lovely speckled effect too!

Side Dishes

Pair these cupcakes with a cool glass of iced tea or a dollop of vanilla ice cream. If you’re hosting brunch, serve them alongside fresh berries and a crisp fruit salad for balance and brightness.

Creative Ways to Present

For a party-worthy look, present Lemon Cupcakes on a tiered stand, alternating garnishes for visual interest. Or, nestle each cupcake in a cupcake wrapper or mini dessert cup with a tiny fork for extra elegance.

Make Ahead and Storage

Storing Leftovers

Keep unfrosted or frosted Lemon Cupcakes in an airtight container at room temperature for up to two days, or refrigerated for up to five. Before serving, let them come to room temp so the buttercream softens up deliciously.

Freezing

To freeze, wrap unfrosted cupcakes individually in plastic wrap, then tuck them into a freezer bag. They’ll stay fresh for up to two months! Thaw overnight in the fridge, then bring to room temperature to enjoy.

Reheating

Pop your cupcakes (unfrosted, if possible) into the microwave for 10–15 seconds to bring back their freshly-baked warmth and softness. If they’re frosted, let them sit out a bit to soften the buttercream before biting in.

FAQs

Can I use bottled lemon juice instead of fresh?

For best flavor, stick with fresh lemon juice! Bottled juice just doesn’t have the same lively, bright kick that makes Lemon Cupcakes so special.

Can I make these cupcakes gluten-free?

Absolutely! Swap in your favorite 1:1 gluten-free flour blend and follow the rest of the recipe as written. The results will be just as moist and tangy.

How do I keep cupcakes moist?

Using sour cream and not overbaking are key for moist Lemon Cupcakes. Make sure to check them a minute or two before the timer goes off and don’t overmix your batter.

Can I double the recipe for a crowd?

Definitely—this recipe doubles beautifully! Just make sure to mix the batter in batches so it stays light, and scale up your buttercream accordingly.

Why do my cupcakes sink in the middle?

Usually, this happens if you overmix or open the oven too soon. Be gentle with your batter and resist the urge to peek before the initial five minutes are up for perfectly domed Lemon Cupcakes.
