Why This Recipe Works
If you are looking to celebrate something, this French-inspired cupcake is the treat you need to make and it couldn’t be easier since it uses a boxed cake mix for the base.
The vanilla cupcakes are infused with St. Germain Elderflower liqueur and are topped with a velvety and super creamy lemon frosting. It’s a flavor match made in heaven.

Even if you aren’t a skilled baker, you can make this dessert! Adding a few ingredients to a boxed cake mix ensures a delicious dessert every time.
These are fun to serve for any girl’s night in or bridal or baby shower. Apparently, Megan Markle served an Elderflower Cake at her recent Royal wedding. Because it’s royally delicious.
Not sure you want to buy a bottle of liquor to make these? You may want to try Rosé Cupcakes, Sangria Cupcakes or Margarita Cupcakes instead.

For the Cupcakes
Boxed cake mix is a great base for boozy cupcakes. I like vanilla for these since it lets the elderflower flavor come through a little bit more.
To the dry cake mix, I add butter, oil and eggs which is pretty typical. But in this recipe, I also add buttermilk. It’s a bit acidic so it really helps to make the cupcake tender.
St. Germain Elderflower Liqueur is added to give that distinctive floral note that is sweet and has a slight citrus note. (Head to the FAQ section to find out some substitution ideas in case you don’t want to use the liqueur.).
For the frosting
I always start with my favorite vanilla buttercream recipe and add flavors as needed based on the recipe I am making. You can always stick with this buttercream, as is, if you don’t want to make the lemon buttercream.
Be sure to head over to that post for the instructions on creating the base. For preparation and planning purposes the recipe uses butter, vegetable shortening, powdered sugar, heavy cream, salt and vanilla extract.
Once the basic recipe is made, you’ll add lemon juice and zest to give it that zing! It’s a quick and easy recipe that is always delicious!
How to make Elderflower Cupcakes
- Preheat oven to 400 degrees. Line a cupcake pan with cupcake liners and set aside.
- In a small bowl combine St. Germain and buttermilk and set aside.
- In a bowl beat the butter until light and fluffy. Add oil and beat until incorporated. Slowly beat in the eggs, adding them one at a time.
- Alternately mix in cake mix and St. Germain/ buttermilk mix in 3 batches, beginning and ending with cake mix.
- Divide the batter evenly between the cupcake liners and put in the oven.
- Turn down the oven to 350 degrees and bake for 15 minutes or until done.
- Remove from the oven and let them cool completely.
Meanwhile, whip up the frosting. (Again, you find those instructions here).
Use a mixer on medium speed to mix up the buttercream. Then mix in the lemon zest and lemon juice.
Decorate the cooled Elderflower Cupcakes with lemon frosting and garnish with fresh thyme sprigs.
I LOVE using fresh herbs to garnish my cupcakes! And thyme pairs really well with both the lemon and elderflower flavors.
These are SO tasty! Of course, you can serve these cupcakes for any occasion, but they are super great for any type of party or even Mother’s Day.
These are spiked cupcakes that your friends will love. You can make these as an edible gift for friends. The flower-y French liqueur makes people feel a little fancy!
Tips and Tricks
- Don’t want to buy a full bottle of the liqueur to make these Lemon and Elderflower Cupcakes? You can always purchase one of the airplane sized bottles from your local wine shop!
- Want even more elderflower liqueur flavor? Brush some directly on to the cupcakes when they are hot out of the oven!
- You can add St. Germain to the buttercream also if you want. Add a tablespoon when you add in the lemon juice and mix. Add more as needed for that perfect flavor. If it gets to runny, add a touch of powdered sugar until you get the right balance.
Frequently Asked Questions
You can use any other brand of elderflower liqueur. If you can’t find that, you could use an elderflower syrup. Or try something else that has floral notes like rose, orange blossom water or a violet liqueur.
I prefer to use a classic vanilla cake mix to make these Lemon and Elderflower Cupcakes but you could also try it with lemon cake mix. Yellow cake mix is also an option that has a more distinct “cake batter” flavor. The vanilla cake mix lets the elderflower flavor shine through best, though.
When you preheat the oven to 400 degrees, it gives the cupcakes a shock of heat that makes them rise in a dome better. Then after the first couple of minutes (anything from 2 to 6 minutes), you can lower the oven temp to 350 so they cook evenly.
St. Germain’s ABV is 20% which is a little more than wine but less than most liquor. Because the amount you add to the batter is not a lot, the chances that these cupcakes will get you drunk is very low. There is also some science around alcohol burning off during baking so I would say these are not going to leave you with a hangover.
