Ingredients You’ll Need

Getting the perfect Moist Lemon Cake with Raspberry Swiss Meringue Buttercream Recipe starts with a handful of simple ingredients that play well together to create incredible texture, vibrant flavor, and beautiful color. Each component brings something important to the table—whether it’s the zingy lemon zest lifting the batter or the luscious butter and cream giving the cake that melt-in-your-mouth richness.

• Frozen raspberries: Use these for the homemade raspberry jam which adds bright, fruity tartness to the buttercream.
• Granulated sugar: Sweetens the cake batter and the raspberry jam perfectly without overpowering the tartness of lemons and berries.
• Lemon juice: Freshly squeezed for authentic, refreshing citrus flavor in both the cake and jam.
• Cornstarch: Thickens the raspberry jam to a silky, spreadable consistency.
• Vanilla extract: Enhances the overall flavor and balances the tartness beautifully.
• Cake flour: Provides a delicate crumb and tender texture needed for moistness.
• Fine sea salt: Just a pinch to elevate all the sweet and fruity notes in the cake.
• Baking powder: Gives the cake that perfect lift and lightness.
• Unsalted European butter: Cubed and at room temperature, it adds richness and a velvety melt.
• Large eggs: Help bind the batter and contribute to the cake’s structure.
• Heavy cream: Adds moisture and tenderness to the cake layers.
• Vegetable oil: Keeps the cake exceptionally moist without weighing it down.
• Large egg whites and granulated sugar (for the frosting): Whisked into a Swiss meringue for that beautiful, fluffy buttercream base.
• Unsalted butter for frosting: Cut into pieces and at a cool room temperature for incorporating into the meringue.
• Reserved raspberry jam: Stirred into the Swiss meringue for a burst of raspberry flavor.
• Fresh raspberries, lemon slices, and freeze-dried raspberries: For gorgeous decoration to finish the cake.

How to Make Moist Lemon Cake with Raspberry Swiss Meringue Buttercream Recipe

Step 1: Prepare the Raspberry Jam

Begin by simmering the frozen raspberries with sugar and a splash of lemon juice over medium heat until the raspberries break down and release their juices. This creates the lush, vibrant base of your jam. Next, mix cornstarch with water and whisk this slurry into the simmering fruit to gently thicken the mixture. Passing the jam through a fine mesh strainer removes pesky seeds, delivering a smooth texture that melts perfectly into the frosting. Stir in vanilla extract for an extra depth of flavor and set aside, reserving half a cup for your buttercream later.

Step 2: Bake the Lemon Cake Layers

Preheat your oven to 350 degrees Fahrenheit (180 degrees Celsius) and prep three 8-inch cake pans by greasing their sides and lining the bottoms with parchment paper. Now rub lemon zest into the sugar to release those essential oils that make your cake wonderfully fragrant. Combine this with cake flour, sea salt, and baking powder. Next, mix in the cubed butter on a low speed until the texture resembles coarse sand — this creates tender pockets in the cake. Whisk together eggs, cream, oil, lemon juice, and vanilla before folding half of this wet mix into the dry ingredients. Scrape down the sides, add the rest, and mix only until just combined to maintain moisture.

Divide the batter evenly and bake for about 18 to 25 minutes until a toothpick inserted in the center comes out with a few moist crumbs clinging to it. Cool them gently as the layers will be delicate but wonderfully tender—exactly what we want!

Step 3: Craft the Raspberry Swiss Meringue Buttercream

This is where the magic happens. Over simmering water, whisk egg whites and sugar until the sugar completely dissolves and the mixture reaches 165 degrees Fahrenheit. Transfer to your mixer and whip at high speed until the meringue cools to around 90–95 degrees. Reduce speed and gradually add the cool butter pieces, incorporating them 1–2 tablespoons at a time to avoid separation. Once smooth and fluffy, fold in the reserved raspberry jam and a pinch of salt for a tangy, rich buttercream that is as decadent as it is light.

Step 4: Assemble Your Cake Masterpiece

Trim the tops of each cake layer to reveal the tender crumb. Place your first layer on a board and spread a thin coat of buttercream directly on the crumb to seal it in. Pipe a buttercream border around the edge to create a barrier, then fill the center with half the raspberry jam for that juicy surprise. Repeat with the next layer and jam, and set the last cake layer upside down for a flat, polished top.

Apply a crumb coat of buttercream all over and chill for 20-30 minutes to keep the filling from spilling out. Finally, cover the cake with the remaining buttercream, piping pretty dollops on top. Decorate it with fresh raspberries, lemon slices, and freeze-dried raspberries for that wow-factor. Refrigerate for at least 4-6 hours, or even overnight, so the flavors marry beautifully and the texture is sublime. Don’t forget to bring it to room temperature before serving to experience the full, tender lusciousness of this Moist Lemon Cake with Raspberry Swiss Meringue Buttercream Recipe!

How to Serve Moist Lemon Cake with Raspberry Swiss Meringue Buttercream Recipe

Garnishes

Fresh raspberries and thin lemon slices highlight the cake’s bright flavors perfectly, adding natural vibrancy and a touch of elegance. Freeze-dried raspberries scattered on top also bring a delightful crunch and an intense berry burst that contrasts beautifully with the smooth frosting.

Side Dishes

This cake pairs wonderfully with light accompaniments such as a scoop of vanilla bean ice cream or a dollop of freshly whipped cream. For a grown-up twist, a glass of sparkling rosé or a refreshing iced tea with lemon complements the citrus and raspberry notes splendidly.

Creative Ways to Present

Try serving this cake as a layered trifle in clear glass bowls with additional fresh berries layered between slices for a show-stopping presentation. Alternatively, you can create petite individual cakes or cupcakes using the same recipe for charming grab-and-go treats perfect for gatherings.

Make Ahead and Storage

Storing Leftovers

Once assembled, your Moist Lemon Cake with Raspberry Swiss Meringue Buttercream Recipe can be stored in an airtight container in the refrigerator for up to 3-4 days. The flavors actually improve after a day, so leftovers are a sweet reward if you can resist right away!

Freezing

If you want to keep this beauty longer, freeze the uniced cake layers wrapped tightly in plastic wrap and aluminum foil for up to 2 months. You can also freeze the assembled cake after crumb coating. Thaw in the fridge overnight before applying the final buttercream layer and decorating.

Reheating

This cake is best enjoyed chilled or at room temperature. To serve, simply allow it to sit out for about 30-45 minutes after refrigeration. Avoid microwaving as it can melt the frosting and change the cake’s delicate texture.

FAQs

Can I use fresh raspberries instead of frozen for the jam?

Absolutely! Fresh raspberries work wonderfully if they are in season and ripe. Just be sure to gently cook them and adjust the cooking time slightly if needed to reach the right consistency for your jam.

Is there a way to make this cake gluten-free?

You can substitute the cake flour with a gluten-free flour blend designed for baking. Just be aware that the texture might be slightly different, and adding a binder like xanthan gum can help provide structure.

Can I prepare the cake layers ahead of time?

Yes! Bake the cake layers a day or two in advance, wrap them tightly to keep moisture in, and store them at room temperature or refrigerated. Bring to room temperature before assembling for the best results.

How do I prevent the Swiss meringue buttercream from separating?

The key is to add the butter slowly while the meringue is at the right temperature and to beat thoroughly but patiently. If it does start to split, keep mixing at low speed, and it will usually come back together.

What’s the best way to serve the cake for a large party?

Serving the cake chilled but at room temperature makes slicing easier and the texture more enjoyable. Use a sharp serrated knife dipped in hot water and wiped dry between cuts for neat slices every time.

Ingredients

Raspberry Jam

• 4 1/2 cups frozen raspberries
• 1/2 cup granulated sugar
• 1 tablespoon lemon juice
• 2 tablespoons cornstarch
• 2 tablespoons water
• 1 teaspoon vanilla extract

Cake

• 1 1/2 cups granulated sugar
• 2 tablespoons fresh lemon zest (packed)
• 3 cups cake flour
• 1 teaspoon fine sea salt
• 1 tablespoon baking powder
• 1 cup cubed unsalted European butter (room temperature)
• 3 large eggs (room temperature)
• 1 1/2 cups heavy cream
• 1/3 cup vegetable oil
• 2 tablespoons fresh lemon juice
• 1 teaspoon vanilla extract

Swiss Meringue Buttercream

• 4 large egg whites
• 1 1/2 cups granulated sugar
• 1 1/2 cups unsalted butter (cool room temperature, cut into tablespoon sized pieces)
• 1/2 cup reserved raspberry jam (from above)
• Pinch of fine sea salt

Decoration

• Fresh raspberries
• Lemon slices
• Freeze dried raspberries

Instructions

1. Make the Raspberry Jam: In a medium saucepan over medium heat, combine frozen raspberries, granulated sugar, and lemon juice. Cook until the raspberries release their juices and the mixture begins to boil, mashing occasionally. In a small bowl, whisk together cornstarch and water to form a slurry. Stir the slurry into the boiling raspberry mixture and cook for 1-2 more minutes until thickened. Strain through a fine mesh to remove seeds and stir in vanilla extract. Reserve 1/2 cup of the jam for the frosting and set both portions aside to cool.
2. Prepare Cake Pans: Preheat the oven to 350°F (180°C). Grease the sides of three 8-inch cake pans and line the bottoms with parchment paper to prevent sticking. Set aside.
3. Combine Dry Ingredients: In a large mixing bowl, rub the fresh lemon zest into the granulated sugar to release aroma. Add the cake flour, sea salt, and baking powder. Whisk together thoroughly to combine.
4. Incorporate Butter: Using a mixer on low speed, mix the cubed butter into the dry ingredients until the mixture resembles sandy crumbs, ensuring butter is evenly distributed.
5. Mix Wet Ingredients: In a separate bowl, whisk together the eggs, heavy cream, vegetable oil, lemon juice, and vanilla extract until smooth.
6. Combine Wet and Dry: Add half of the wet ingredients into the flour mixture, mixing until all the flour is moistened. Scrape down the sides of the bowl. Add the remaining wet ingredients, pulsing initially and then mixing on low speed until just combined, creating a thick batter.
7. Fill and Bake: Divide the batter evenly among the prepared cake pans (approximately 485 grams per pan). Smooth the tops with a spatula. Bake for 18-25 minutes until a toothpick inserted in the center comes out with a few moist crumbs. Allow pans to cool on wire racks for 20 minutes before carefully removing the cakes to finish cooling completely on racks.
8. Make Swiss Meringue Buttercream: Place egg whites and sugar into a heatproof bowl set over a double boiler with simmering water. Whisk constantly until the sugar dissolves and the mixture reaches 165°F. Transfer the mixture to a stand mixer and whip on high speed until it cools to 90-95°F (about 10-15 minutes), forming stiff, glossy peaks.
9. Add Butter: Reduce mixer speed to low and add the butter in small tablespoons at a time, mixing until fully incorporated. Increase speed to medium-high and beat until the frosting is light and fluffy. Fold in the reserved raspberry jam and a pinch of sea salt to flavor the buttercream.
10. Assemble the Cake: Level the tops of each cake layer by trimming a thin layer with a serrated knife to expose the crumb. Place the first layer on a serving board. Spread a thin layer of buttercream on the crumb, pipe a border of buttercream around the edge of the cake, and fill the center with half the raspberry jam. Repeat with the second layer, then place the last layer upside down for a flat top.
11. Crumb Coat and Chill: Apply a thin layer of buttercream around the entire cake to seal crumbs. Refrigerate for 20-30 minutes to firm the coating, helping to prevent filling from spilling.
12. Final Frosting and Decoration: Cover the cake with the remaining buttercream evenly on sides and top. Pipe decorative dollops using any leftover frosting. Garnish with fresh raspberries, lemon slices, and freeze-dried raspberries. Refrigerate for 4-6 hours or overnight to enhance flavor and texture. Bring to room temperature before serving.

Notes

• When measuring cake flour, spoon the flour into your measuring cup and level off with a knife to avoid packing, resulting in lighter cakes.
• Use European style butter for best flavor and texture; it typically has a higher fat content than regular butter.
• Room temperature ingredients help achieve a smooth batter and even mixing.
• Be gentle when handling the cake layers as they are delicate and can break easily.
• Allowing the cake to marinate overnight improves moisture and flavor melding.
• Ensure the meringue is cooled properly before adding butter to avoid separation in the buttercream.
• Use a thermometer when making the meringue to ensure sugar is fully dissolved and to achieve proper stage for whipping.
