    Lemon curd cupcakes

    If you like lemon desserts then you absolutely must try this delicious and tasty lemon cupcake recipe filled with a creamy lemon curd heart and topped with a light and fluffy mascarpone frosting.

    Lemon curd is a lemon-flavored filling made with eggs, butter, sugar, and lemon juice, that is usually used to garnish a lemon tart, but it can also be used as a cake filling, as in this recipe for a lemon cupcake.

    These cupcakes are moist and it's just my basic vanilla cupcake recipe that I flavored with lemon zest and fresh lemon juice for a delicious tart flavor.

    Topped with a mascarpone whipped cream frosting for an alternative to Italian meringue or lemon buttercream frosting. This creamy frosting is perfect for balancing the lemony flavor of the lemon curd.

    This easy lemon cupcakes recipe is perfect for all lemon lovers, a perfect dessert for any occasion or just to enjoy the citrus season.

    Ingredients and substitutions

    Here are the ingredients you will need to make these delicious lemon cupcakes at home and possible substitutions, scroll down to see the quantities in the recipe card.

    Lemon cupcakes

    • Butter: Use unsalted butter that is well softened, take it out in advance or warm it up a bit in the microwave before starting the recipe.
    • Sugar: preferably granulated sugar and not flavored to preserve the flavor of the lemon.
    • Eggs: at room temperature, run them under hot water for a few moments to bring them back to temperature more quickly.
    • Vanilla and salt: essential for flavoring and bringing out the flavors.
    • Milk: preferably buttermilk for softer cupcakes. You can replace it with half-skimmed milk or plain yogurt.
    • Flour: Wheat flour like cake flour or all-purpose flour, which you can substitute with a gluten-free flour blend to make a gluten-free version.
    • Baking powder: measure the quantity with a scale, To use baking soda instead, reduce the quantity indicated in the recipe card.
    • Lemon flavor: essential to flavor the lemon cupcakes recipe with zest and fresh juice of an untreated and organic lemon if possible. You can replace it with bottled lemon juice.

    Lemon Curd

    As an option, lemon curd is added to the heart of the cupcake after baking when they are completely cooled, it brings a delicious lemon and creamy flavor, perfect in this recipe.

    Mascarpone Frosting

    Mascarpone whipped cream frosting is one of my favorite frosting recipes to fill and decorate layer cake recipes and cupcakes. Made with only 3 ingredients, mascarpone cheese, full heavy cream and powdered sugar.

    It's a light textured frosting that adds a touch of freshness, perfect for softening the acidity of the lemon, but it's a rather fragile cream that requires refrigeration.

    You can replace it with another flavored lemon frosting such as a Swiss meringue buttercream, a cream cheese frosting with my cbuttercream cream cheese frosting or vanilla whipped ganache.

    ⚠️ You will find the quantities and complete instructions in the recipe card at the end of the page.
