These cupcakes bring elegance to casual gatherings and a playful surprise to formal ones.

Instructions

Step 1: Make the Lemon Curd

In a small saucepan, whisk together the egg yolks, sugar, lemon zest, juice, and salt. Cook over medium heat, stirring constantly, until the mixture thickens (about 8–10 minutes). Remove from heat and whisk in butter until smooth. Transfer to a bowl, cover, and refrigerate until cooled.

Step 2: Bake the Cupcakes

Preheat your oven to 350°F (175°C). In a bowl, whisk together flour, baking powder, and salt. In a separate large bowl, beat butter and sugar until fluffy. Add eggs one at a time, then mix in vanilla. Alternate adding the dry ingredients and milk until combined. Divide batter into cupcake liners and bake for 18–20 minutes, or until a toothpick comes out clean. Let cool completely.

Step 3: Make the Frosting

Beat butter until smooth, then gradually add powdered sugar. Mix in lemon juice until light and fluffy.

Step 4: Assemble the Cupcakes

Once cooled, use a knife or piping tip to carve a small hole in the center of each cupcake. Spoon or pipe in the chilled lemon curd. Top with swirls of lemon frosting.

Serving Suggestions

These cupcakes shine at spring picnics, baby showers, and summer parties. Pair with iced tea or sparkling lemonade for a refreshing combo. For extra flair, garnish each cupcake with a lemon slice twist or candied zest.

Storage Tips

Room temperature: Cupcakes without curd can sit covered for up to 2 days.
Refrigerated: Filled cupcakes last 3–4 days in an airtight container.
Freezer: Cupcakes (without curd or frosting) can be frozen for up to 2 months. Defrost and fill/frost when ready.
