INGREDIENTS
Lemon Curd
- 5 egg yolks, room temperature
- 1 cup granulated sugar
- ⅓ cup fresh lemon juice (about 4 – 5 lemons)
- Zest of 4 lemons
- ½ cup (1 stick, 8 tablespoons) unsalted butter, cut in cubes
Sprinkle Bark
- 10 oz white chocolate
- 3 – 4 tablespoons sprinkles, plus more sprinkles for sprinkling on the cupcakes
Vanilla Cupcakes
- 1 ½ cups cake flour (can also use unbleached all-purpose flour)
- 1 ½ teaspoons baking powder
- ¾ teaspoon salt
- ½ cup (1 stick, 8 tablespoons) unsalted butter, room temperature
- 1 cup granulated sugar
- ½ vanilla bean pod, beans scraped out
- 2 large eggs, room temperature
- 1 ½ teaspoons vanilla extract
- ½ cup buttermilk, room temperature
Vanilla Buttercream Frosting
- ¾ cups (1 ½ sticks, 12 tablespoons) unsalted butter, room temperature
- 2 ½ - 3 cups powdered sugar
- ½ vanilla bean pod, beans scraped out
- 1 teaspoon vanilla extract
- Pinch of salt
- 2 -3 tablespoons heavy cream
INSTRUCTIONS
- Make the curd. In a large metal bowl or saucepan, beat the eggs and sugar together until light in color. Add the lemon juice and zest to the egg mixture and beat well until combined.
- Place over a small saucepan filled with one inch of simmering water so that your bowl or saucepan does not directly touch the water.
- Continue to beat the egg mixture until it become thick , light yellow, and you can leave a trail on the back of a spoon that’s been dipped in the mixture.
- Remove from heat and add the butter, stir until the butter is completely combined into the mixture.
- Put the curd through a fine mesh strainer to remove any cooked bits and the zest. Store in an airtight jar and refrigerate until completely chilled. Note: if you are making these cupcakes in one day, take about ⅔ cups of the curd and place in a ziplock bag. Spread out the curd in the bag and lay flat to chill. That will speed up the process. To use, simply push the curd into one section of the ziplock bag and cut the corner to create a makeshift piping bag! The curd can be make up to a week in advance.
- Make the spinkle bark. Using the same small saucepan with simmering water (you may need to add a bit more water to the pan) and a clean bowl or large saucepan, add your white chocolate. Stir the mixture until the white chocolate is completely melted. Add in the sprinkles and stir to combine.
- Pour the white chocolate onto a parchment-lined baking sheet and spread out until roughly ¼ inch thick using an offset spatula. Allow to harden at room temperature as you make the cupcakes.
- Make the cupcakes. Preheat the oven to 350 degrees F. Line a muffin tin with cupcake liners. In a medium bowl, add the flour, baking powder, and salt. Whisk to combine and set aside.
- Beat the butter, sugar, and beans from the vanilla bean pod until light and fluffy. Add the eggs one at a time and beat well (at least a minute) between each addition. Add in the vanilla extract and beat well.
- Alternate between adding the flour and buttermilk to the mixture. Begin and end with the flour. The flour should be added in three additions, while the buttermilk should be added in two additions.
- Evenly divide the batter among the cupcake liners and bake for about 12 – 15 minutes, or until a toothpick comes out clean when inserted and the cake springs back when gently pushed. Turn the pan halfway between baking.
- Remove the cupcakes from the oven and allow to cool completely on a wire rack as you make the buttercream.
- Beat the butter until smooth. Add the powdered sugar ½ cup at a time, beating well between each addition. Add the salt, vanilla beans from the vanilla bean pod, vanilla extract, and heavy cream, Beat until just combined. Note: I like to beat on low, or by hand for a few minutes at the end to remove any air that may have incorporated into the buttercream.
- Assemble the cupcakes. Remove the centers of the cupcakes and fill with the lemon curd. Fit a piping bag with your favorite tip and fill with the buttercream. Pipe the frosting onto your cupcakes. Cut up shards of the bark and place on the cupcakes. Top the frosting with more sprinkles, if desired.
NOTES
I recommend using Rodellevanilla beans and vanilla extract
