Why I Love This Recipe

These cupcakes stand out for several reasons.

First, the lemon flavor is layered. Lemon zest and juice are baked into the cupcakes, lemon curd is hidden inside, and the frosting has another hint of citrus.

Second, the cupcakes have a perfectly soft and moist texture thanks to buttermilk and butter.

Finally, they look beautiful when finished with a swirl of frosting and a sprinkle of lemon zest, making them perfect for entertaining or gifting.

Step-by-Step Instructions

1. Make the Lemon Curd

In a heatproof bowl, whisk together:

• Egg yolks
• Sugar
• Lemon zest
• Lemon juice

Place the bowl over a saucepan with simmering water (double boiler method).

Whisk constantly for 8–10 minutes, until the mixture thickens enough to coat the back of a spoon.

Remove from heat and whisk in the butter until smooth.

Cover with plastic wrap pressed against the surface and refrigerate until fully chilled.

2. Prepare the Cupcake Batter

In a bowl, whisk together:

• Flour
• Baking powder
• Baking soda
• Salt

---

3. Cream Butter and Sugar

In a large bowl, beat the butter and sugar together until light and fluffy, about 2–3 minutes.

Beat in the eggs one at a time.

Mix in vanilla extract, lemon zest, and lemon juice.

---

4. Combine Batter

Alternate adding the dry ingredients and buttermilk to the batter.

Start and end with the dry ingredients and mix just until combined.

---

5. Bake the Cupcakes

Divide the batter evenly among the cupcake liners, filling each about two-thirds full.

Bake for 18–20 minutes or until a toothpick inserted into the center comes out clean.

Let the cupcakes cool completely.

---

6. Fill the Cupcakes

Cut a small hole in the center of each cupcake.

Fill with chilled lemon curd and replace the top piece if desired.

---

7. Make the Frosting

Beat cream cheese and butter together until smooth.

Add vanilla extract and optional lemon juice.

Gradually beat in powdered sugar until the frosting becomes fluffy and spreadable.

---

8. Frost and Garnish

Pipe or spread the frosting onto the cupcakes.

Garnish with lemon zest or a small dollop of lemon curd.

Tips for Success

Use fresh lemons
Fresh juice and zest make a huge difference in flavor.

Don’t overmix the batter
Overmixing can make cupcakes dense.

Cool cupcakes completely before filling
Warm cupcakes can melt the lemon curd.

Chill the curd
Cold lemon curd is easier to pipe into the cupcakes.
