Lemon and raspberry cupcakes consist of moist lemon cake, raspberry jam filling, and a bright raspberry Swiss meringue buttercream frosting. Raspberry jam in the center of each cupcake in addition to the raspberry frosting, elevates these fluffy lemon cupcakes into a delightful spring and summer dessert.
🌿 Ingredients You'll Need
- All Purpose Flour or Pastry Flour creates structure for jam filled moist lemon cupcakes.
- Baking Powder and Baking Soda are used to make the cupcakes rise.
- Unsalted Butter for the cake and buttercream.
- Granulated Sugar adds a subtle sweetness to the cake crumb and also enhances the oils from the fresh lemon zest.
- Large Eggs provide structure and moisture to the cake, while additional egg whites are used to create the meringue base for the buttercream.
- Whole Milk or Buttermilk can be used interchangeably for to add moisture to the cake crumb. Buttermilk gives a slight tanginess to the cake and pairs nicely with the lemon.
- Fresh Lemons are a must to add in lots of lemon zest and fresh lemon juice into the cupcake batter. You will need 3 tablespoons of fresh lemon zest. No need for lemon extract.
- Vanilla Extract or Vanilla Bean Paste
- Fresh Raspberries for making the fresh raspberry cake filling. The homemade raspberry jam adds fruity flavor to the lemon cupcakes along with a bright pink color to the raspberry frosting.
- Store-bought Raspberry Jam mixed with fresh raspberries is a quick alternative to making homemade jam. Keep in mind that store-bought jam will be much sweeter. My favorite brand to use for this recipe is Bonne-Maman raspberry preserves.
Making Raspberry Lemon Cupcakes
- Make the raspberry cake filling or raspberry jam first. Homemade fruit preserves need time to cool, so having your jam ready to go makes cupcake assembly go smoother.
- If you're using store bought raspberry preserves, you're all set. Just remember store jam is going to be much sweeter than homemade, so mix in some fresh raspberries for best results.
- Zest the lemon into the sugar. Give the zest and sugar a good rub with your fingertips to release the lemon oils into the sugar. This step is a must for infusing the most lemon flavor into your cupcakes.
- Fill Lemon Cupcakes with raspberry jam. Adding extra raspberry flavor into the cupcake takes them to the next level. Super easy to do, just take a small paring knife and cut a circle out of the center tops of the cupcakes. Removing about a teaspoon or two of cake crumbs with a lemon baller or teaspoon. Fill the hole with raspberry jam and you're all set.
Equipment Needed
- Stand Electric Mixer for making the cupcake batter and the buttercream frosting.
- 12-Cup Cupcake Pan
- Cupcake Paper Liners
- Piping bag with desired tip for piping frosting.
Cupcake Baking Tips
What Baking Ingredients I Use and Why
Weigh Your Ingredients:
The recipe card includes both metric and US conversions, but since I create all my recipes with metric measurements, I can't guarantee the same results if you use a different measuring method. This is the kitchen scale I use everyday.
Use High Quality Butter:
Make the cake batter with rich European style butter with 82% butterfat for the best flavor. Try brands like President, Plugra, Kerry Gold, or Vermont Creamery if you're in the States.
Use Softened Butter:
Cold butter from the refrigerator will not cream properly with the sugar in the cake and the buttercream. Be sure to set the butter out on the counter at least an hour or more before baking.
Infuse the Sugar with Lemon Flavor:
To really enhance the taste of lemon in your cupcakes, work the zest into the sugar. Use your fingertips to rub the zest and sugar together before beating in the butter.
Raspberry Swiss Meringue Buttercream Tips
Clean Your Mixing Bowl and Whisk:
I always wipe down my mixing bowl, whisk, and paddle attachment with lemon juice to remove any possible oil residue before whipping egg whites.
Use High Quality Butter:
Make the buttercream with rich European style butter with 82% butterfat for the best flavor. Try brands like President, Plugra, Kerry Gold, or Vermont Creamery if you're in the States. American butter will also work if that's what you have available.
Use Softened Butter:
To soften butter, I place set cold butter on the counter for several hours to warm to room temperature. Or if I'm in a hurry, I'll microwave unwrapped chunks in a heat proof bowl at 20 second spurts until soft, but not warm, melted, or oily.
Check Meringue Temperature:
Ensure the meringue whips to stiff peaks and the bowl cools before adding the butter, or it will melt into a soupy mess. I use a thermometer to check that the meringue reaches 75°F (23°C) before adding the butter.
Curdled Meringue Buttercream:
Its totally normal for the buttercream to look soupy or curdled after adding in the butter, give it time and keep whipping.
Buttercream Too Cold:
If the mixture does not come together and stays curdled after 5 to 10 minutes, you can warm it slightly by place the mixing bowl back onto the double broiler and let just the edges of the meringue warm up before continuing to mix it.
Or remove ¼ of the meringue and melt it slightly in the microwave, then pour it back into the mixing bowl and beat again until smooth. *You can also heat the side of the bowl gently with a blow torch while mixing, just enough to warm slightly.
Buttercream Too Warm:
Place the bowl of buttercream in the fridge for 10 minutes if it hasn't turned to frosting after all of the butter has been added and you've been whipping on high speed for at least 5 minutes. Chill the buttercream and then whip again until smooth.
Buttercream Frosting is Melting:
Just a reminder that all buttercream uses butter and can melt if its humid or hot. I keep frosted cupcakes at room temperature, out of the sun, or stored in the fridge.

Instructions
Raspberry Jam Cake Filling
- Place raspberries, sugar, and lemon juice in a medium saucepan over medium heat for 10-12 minutes until boiling, mash with a wooden spoon to help break down the berries.
- Whisk together the cornstarch and water in a small bowl, then stir into the jam. Cook for an additional 1-2 minutes until thickened.
- *Option to press jam through a metal mesh sieve while its still warm to remove the seeds.
- Transfer jam to a heat proof container or bowl to cool completely before assembling cupcakes. Jam can also be made ahead and stored in air tight container.
Cupcake Batter
- Preheat Oven to 350℉ / 180℃ / 160℃ Fan (convection). Line a 12-cavity cupcake pan or 6 cavity large muffin pan with paper cupcake liners.
- In a medium bowl, hand whisk together sifted flours, salt, and baking agents. Set aside.
- Place the sugar and lemon zest into the bowl of a stand mixer. Work the zest into the sugar by rubbing it together with your fingertips. Add in the flour mixture and mix together on low speed with the paddle attachment to distribute.
- Add in the softened butter and mix until just combined.(about 1 minute). It should look like a shaggy corneal texture.
- In a small bowl whisk together the eggs and vanilla. Pour the egg mixture into the batter and beat on medium high for 2-3 minutes until light and fluffy. Scrape the bottom and sides of your bowl to catch any ingredients that are just hanging around.
- Lastly, pour in the lemon juice and buttermilk slowly until the cake batter is smooth and fluffy. Scrape the sides and bottom of the bowl one last time to make sure everything is mixed in.
- Divide the cupcake batter into the paper liners of your pan. Fill them ¾ of the way full to create a small dome when baked. I use a large ice cream scoop to make measuring easier.
- Bake 12-cavity regular cupcakes for 15-18 minutes or the 8-cavity jumbo cupcakes for 20-25 minutes until lightly golden or when a toothpick inserted into the center comes out clean. Repeat with remaining batter.
- Place cupcake pan on wire cooling rack to cool 10 minutes. Remove each cupcake and place on rack to cool completely before decorating.
Fill the Cupcakes
- Take a small knife and cut a circle out of the center top of each cupcake. Removing about a teaspoon or two of cake crumbs with a lemon baller or teaspoon. Fill the holes with raspberry jam.
Raspberry Swiss Meringue Buttercream
- Clean and dry your stand mixer bowl and whisk attachment. Wipe down lightly with lemon juice to remove any residue.
- Add the egg whites and sugar to the bowl of a stand mixer. Create a double boiler by placing the bowl over a pot of shallow simmering water. Do not let the mixing bowl touch the water.
- Whisk the egg whites and sugar continuously until the temperature on an instant thermometer reads 160℉ (72℃). Carefully dip your finger into the hot sugar and rub the mixture between your fingertips. If you don't feel any grains of sugar, the mixture is ready. (about 6-8 minutes)
- Remove the mixing bowl from the heat and wipe the bottom of the bowl dry with a towel. Place the bowl on the mixing stand fitted with the whisk attachment and begin whipping on medium-high speed.
- Continue to whip until a thick, glossy and marshmallow like meringue with stiff peaks is formed. The bowl should no longer be warm or at least room temperature to the touch. Its ok if the very bottom of the bowl is slightly warmer than room temperature. (about 10-15 minutes)
- Switch to the paddle attachment on the mixer. (You can continue with the whisk attachment if you prefer and switch to the paddle attachment at the end to beat out any air bubbles.)
- While mixing on medium speed drop in one tablespoon of butter at a time into the whipping meringue. Wait for each piece of butter to mix-in before adding the next.
- You may notice the meringue losing its stiffness and becoming softer, that's ok, keep adding butter.
- Once half of the butter has been mixed in, stop the mixer and scrape the bottom and sides of the bowl to grab any stuck meringue or bits of butter. We want all the butter to emulsify with the meringue.
- Continue mixing and add in the remaining butter.
- The meringue may deflate and look runny or split, but keep mixing for another 10-15 minutes after all the butter has been added on medium speed.
- If after 10 minutes of mixing it hasn't magically transformed into a frosting texture, just place the bowl in the fridge for 10 minutes with the paddle attachment. Then, whip again until silky smooth.
- Once the buttercream looks like a spreadable frosting add in the vanilla bean paste and salt, then give it a couple spins on low to mix.
- Add in the raspberry jam and mix in on low speed.
- If you would like your frosting to have more color, mix in a couple drops of gel food color.
- If there are a bunch of air bubbles in the frosting, mix on low speed with the paddle attachment until smoother.
- Transfer buttercream to a large piping bag with desired piping tip. Pipe starting on the outer edges, working your way into the middle of each cupcake in a circular motion. Lift up once you reach the center. Repeat with remaining cupcakes.

These cupcakes are beautiful and delicious! I loved the tart raspberry flavor in the icing and the berry on top. What a great flavor profile with the lemonade cake. Once you eat one, you are definitely going to want another one.
