Jump to Recipe

I love how these Easy Homemade Moist Lemon Cupcakes surprise people. The cake is unbelievably tender and the creamy lemon buttermilk frosting somehow makes each bite sing.

I stir bright lemon zest into the batter and add buttermilk for that silky texture, so it feels both simple and a little fancy. Folks joke calling them Ванильные Кексы at first, then eat like three more and start calling them classic Кексы.

I mess things up sometimes, trust me, but this one rarely fails and it always makes guests curious to know what the secret was.

Print Recipe (No Advertisments)

1. Preheat oven to 350°F (175°C) and line a 12 cup muffin tin with liners, let your butter and eggs come to room temp if you forgot earlier it’s ok.

2. In a bowl whisk together 1 1/2 cups all purpose flour, 1 cup granulated sugar, 2 tsp baking powder, 1/4 tsp baking soda and 1/4 tsp salt until evenly mixed.

3. In a large bowl cream 1/2 cup softened unsalted butter with the sugar until light, beat in 2 large eggs one at a time, then stir in 1 tsp vanilla extract, 2 tbsp fresh lemon juice and 2 tbsp lemon zest.

4. Add the dry mixture to the butter mixture in 2 or 3 additions alternating with 1/2 cup buttermilk, beginning and ending with the dry ingredients, mix just until combined don’t overmix or cupcakes get tough.

5. Spoon batter into liners about two thirds full, tap the pan once to settle batter and pop any big air bubbles.

6. Bake 18 to 22 minutes until tops are lightly golden and a toothpick comes out with a few moist crumbs, let cupcakes cool in the pan 5 minutes then transfer to a wire rack to cool completely before frosting.

7. For the lemon buttermilk frosting beat 1 cup softened unsalted butter until creamy, gradually add 3 to 4 cups powdered sugar while beating, add 2 to 3 tbsp buttermilk as needed to reach spreading consistency and mix in 2 tbsp fresh lemon juice, 1 tsp lemon zest, 1 tsp vanilla extract and a pinch of salt; adjust with more sugar to thicken or more buttermilk to thin.

8. If you want a surprise center, core cooled cupcakes with a small spoon or piping tip and fill with lemon curd or fresh berry jam, then replace the little cake piece.

9. Frost cooled cupcakes with a knife or piping bag, press a few fresh berries or a little extra zest on top for sparkle; if the frosting gets too soft pop it in the fridge for 10 minutes.

10. Store in an airtight container at room temp for up to 2 days or in the fridge up to 5 days, bring back to room temp before serving for best texture.

Equipment Needed

1. 12-cup muffin tin and paper liners
2. Measuring cups and spoons
3. Mixing bowls (large for batter, medium for dry/frosting)
4. Electric mixer (hand or stand) or a sturdy whisk if you wanna do it by hand
5. Rubber spatula and wooden spoon for scraping and folding
6. Citrus zester or fine grater for lemon zest
7. Ice cream scoop or two spoons to portion batter; small spoon or coring tool/piping tip for filling
8. Wire cooling rack and a toothpick or cake tester to check doneness
9. Piping bag with tip or an offset spatula for frosting and decorating

FAQ

Q: How long and at what temperature do I bake these lemon cupcakes? A: Bake at 350°F (175°C) for about 18 to 22 minutes. They're done when a toothpick comes out clean or with a few moist crumbs. Don't open the oven early, or they might sink, trust me it happens.

Q: I don't have buttermilk, what can I use instead? A: Use regular milk plus acid. For each cup of milk stir in 1 tablespoon lemon juice or vinegar, let sit 5 minutes. For this recipe use 1/2 cup milk plus about 1/2 tablespoon lemon juice or vinegar.

Q: How do I keep the cupcakes really moist? A: Don't overmix the batter, cream butter and sugar until light, measure flour by spooning into the cup and leveling, and don't overbake. For extra moistness brush warm cupcakes with a little lemon simple syrup (equal parts sugar and water, a splash of lemon juice).

Q: My frosting is too thin or too thick, how do I fix it? A: To thicken add more powdered sugar, a little at a time. To thin add 1 teaspoon buttermilk at a time until you reach the texture you want. If it gets too soft chill it for 10 to 20 minutes, then rewhip for fluff.

Q: Can I make these ahead or freeze them? A: Yes. Unfrosted cupcakes freeze well up to 3 months, wrap individually and store in an airtight container. Frosted cupcakes can be frozen up to 1 month if well wrapped. Thaw in the fridge, then bring to room temperature before serving.

Q: Why did my cupcakes sink in the middle? A: Common reasons are underbaking, oven temperature too low, opening the oven door early, too much leavening, or overbeating the batter. Use room temperature eggs and follow the baking time, and they'll behave better next time.

Easy Homemade Moist Lemon Cupcakes Recipe Substitutions and Variations

Buttermilk: if you dont have buttermilk mix 1 cup milk with 1 tbsp lemon juice or vinegar, let sit 5 minutes until slightly thickened; or use plain yogurt or sour cream thinned with a splash of milk to the same consistency; for dairy free use unsweetened almond or soy milk + 1 tbsp lemon per cup.
Unsalted butter: swap equal amount of salted butter and skip the pinch of salt in the recipe (one stick / 1/2 cup salted butter has about 1/4 tsp salt); for a moister cupcake you can use 3/4 cup neutral oil (vegetable or canola) for every 1 cup butter called, but note oil wont make a stable buttercream frosting.
All purpose flour: for a lighter crumb use cake flour instead (you can make it by taking 1 cup AP, removing 2 tbsp, then stirring in 2 tbsp cornstarch), or use whole wheat pastry flour 1:1 for a nuttier, slightly denser cake; for GF use a 1:1 gluten free baking blend.
Granulated sugar: swap 1:1 with light brown sugar for extra moisture and caramel notes (cupcakes will be a bit darker), or use coconut sugar 1:1 as a lower GI option; if you try liquid sweeteners like honey or maple syrup reduce other liquids and lower oven temp slightly so it doesnt overbake.

Pro Tips

– Zest first, then juice the lemons. If you juice first you lose the easiest source of bright lemon flavor, and the white pith under the peel is bitter so scrape that off. A fine grater or microplane gives the best aroma, and you can stash extra zest in the freezer for later.

– Measure flour carefully, preferably by weight or by spooning it into the cup and leveling it off. Overpacked flour and overmixing are the two fastest ways to end up with dense, tough cupcakes, so stop mixing as soon as you cant see streaks of flour.

– If your buttercream gets too soft, chill the bowl for 10 minutes and then whip again, or add a tablespoon of cream cheese or a teaspoon of meringue powder to help it hold shape in warm weather. Start with less liquid than you think you need, and thin with small splashes of buttermilk until you hit the right consistency.

– For extra moistness and a flavor boost, brush cooled cupcakes lightly with a lemon simple syrup (equal parts sugar and lemon juice warmed until the sugar dissolves) before frosting. It keeps them from drying out and makes the lemon flavor pop without changing the crumb.
