Vanilla Cupcakes
- Prepare the Oven and Pan: Preheat the oven to 350°F. Line a 12-cup cupcake pan with paper liners, or grease the cups with butter and dust them with flour.
- Sift the Dry Ingredients: Sift the all-purpose flour, baking powder, baking soda, and fine sea salt into a bowl. Set aside.
- Cream the Butter: Beat the softened butter in an electric mixer at medium speed for approximately 1 minute until smooth.
- Add the Sugar: Add the granulated sugar and beat for another 2 minutes until the mixture is creamy and fluffy. Scrape down the sides of the bowl as needed.
- Incorporate the Eggs: Add the eggs one at a time, mixing well after each addition before adding the next.
- Add the Vanilla: Mix in the vanilla extract until evenly combined.
- Mix in the Milk: Gradually add the room-temperature milk, stirring until incorporated.
- Fold in the Dry Ingredients: Add the sifted dry ingredients and gently fold until just combined.
- Fill the Cupcake Pan: Divide the batter evenly among the 12 prepared cupcake cups.
- Bake the Cupcakes: Bake at 350°F for approximately 15 minutes, rotating the pan during baking for even results. Allow a few additional minutes if needed.
- Check for Doneness: Gently press the top of a cupcake. It should spring back when ready. If necessary, continue baking briefly and check again.
- Cool Completely: Let the cupcakes cool completely before filling and frosting.
Pomegranate Jam
- Combine the Ingredients: Place the pomegranate seeds, pomegranate juice, and lemon juice in a small saucepan.
- Boil the Mixture: Bring the mixture to a boil over medium heat, stirring constantly.
- Simmer the Fruit: Simmer for approximately 10 minutes until the seeds soften. If the mixture becomes too dry, add a little more pomegranate juice.
- Prepare the Cornstarch Slurry: Mix the cornstarch with the cold water in a small bowl until smooth.
- Thicken the Jam: Stir the cornstarch mixture into the saucepan. Bring it back to a boil, then simmer gently until the jam becomes very thick.
- Strain the Jam: Immediately pour the mixture through a fine-mesh strainer over a bowl. Press and stir the seeds vigorously to extract as much jam as possible, scraping the underside of the strainer as needed.
- Cool the Jam: Discard the remaining seeds and refrigerate the strained jam until completely cool.
Swiss Meringue Buttercream
- Soften the Butter: Remove the butter from the refrigerator approximately 30 minutes before preparing the buttercream. Slice it into pieces about 1/4 inch thick and leave at room temperature until softened but not melted. This may take an hour or longer, depending on your kitchen.
- Combine Egg Whites and Sugar: Place the egg whites and granulated sugar in a heatproof bowl or the top of a double boiler.
- Heat Over Simmering Water: Bring a pot of water to a boil, then reduce it to a simmer. Place the bowl over the simmering water.
- Heat the Mixture: Whisk constantly until the mixture reaches 138°F. Remove it from the heat and continue whisking for approximately 30 seconds.
- Transfer to the Mixer: Pour the mixture into a stand mixer bowl, ensuring that condensation from the outside and bottom of the bowl does not enter the meringue.
- Whip the Meringue: Using the whisk attachment, beat at medium-high speed until stiff peaks form. This usually takes approximately 10 minutes while the mixture cools.
- Check the Consistency: Continue whipping until the meringue holds stiff peaks and has cooled sufficiently.
- Add the Butter: With the mixer running at medium-high speed, add the softened butter one slice at a time, waiting a few seconds between additions.
- Finish the Buttercream: Add the vanilla extract after incorporating all the butter. Continue beating until the buttercream becomes smooth, creamy, and firm.
Assemble and Decorate
- Hollow Out the Cupcakes: Use a spoon to remove a small portion from the center of each completely cooled cupcake.
- Fill the Cupcakes: Spoon the chilled pomegranate jam into the centers and replace the removed cupcake tops.
- Color the Buttercream: For a swirled effect, divide the buttercream between two bowls. Leave one portion white and color the other pink, red, or burgundy. You can combine pink, red, burgundy, and a tiny touch of blue for a deeper shade.
- Layer the Frosting: Lay a sheet of plastic wrap on the counter. Spread the colored frosting over it, then spread the white frosting on top.
- Form the Frosting Log: Roll the plastic wrap around the layered frosting to create a log.
- Prepare the Piping Bag: Place the frosting log inside a piping bag fitted with your preferred piping tip.
- Pipe the Cupcakes: Pipe the frosting over each filled cupcake to create a decorative swirl.
- Add Decorations: If desired, finish with pomegranate macarons, meringue cookies, and fresh pomegranate seeds.
Notes
-
Room-temperature ingredients: Use room-temperature eggs and milk for the cupcakes to help the batter combine smoothly.
-
Avoid overmixing: Fold the dry ingredients into the wet mixture just until incorporated to maintain a tender cupcake texture.
-
Check the cupcakes carefully: Begin checking for doneness after approximately 15 minutes. The tops should spring back when gently pressed.
-
Adjust the jam consistency: If the pomegranate mixture becomes too dry while simmering, add a little more pomegranate juice before thickening it with the cornstarch slurry.
-
Strain thoroughly: Press the cooked pomegranate seeds firmly through the strainer to extract as much flavorful jam as possible.
-
Cool the filling completely: Refrigerate the pomegranate jam until cold before filling the cupcakes to help prevent it from softening the buttercream.
-
Use properly softened butter: The butter for the Swiss meringue buttercream should be soft enough to incorporate easily but not melted or excessively warm.
-
Be patient with the meringue: Allow sufficient time for the egg-white mixture to cool and form stiff peaks before adding the butter.
-
Customize the decoration: The two-tone frosting is optional. Plain vanilla buttercream also works beautifully for a simple finish.
-
Storage: Keep the cupcakes covered in the refrigerator for up to 3 days.
