Feel free to adapt this recipe to suit your tastes and strengths in the kitchen! Purchase pre-made lemon curd which can be found in the jelly section of your local supermarket. Feel free to make it in staged as well: the cooled, cordial-brushed cakes can be made a day or two in advance, simply wrap well in plastic and store in the fridge until ready to assemble. The buttercream frosting can also be made a day in advance, simply stir or use a mixer to smooth out consistency. NOTE: Belvoir Elderflower Pressé can be found at most high end grocery stores like Fresh Market and Whole Foods.
Ingredients
  • FOR THE CAKE:
  • 8 Tablespoons unsalted butter (1 stick) at room temperature, plus more to grease cake pans
  • 1 cup granulated sugar
  • 1 Tablespoons finely grated lemon zest (from 1 lemon, reserve juice for use in frosting)
  • 3 large eggs at room temperature
  • 1 teaspoon vanilla extract
  • ½ teaspoon Kosher salt
  • 2 cups flour
  • 2 teaspoons baking powder
  • 1 teaspoon St. Germain or other elderflower liqueur
  • ⅔ cup whole milk
  • ½ cup elderflower cordial (i.e. Belvoir Elderflower Presse)
  • FOR THE FILLING:
  • 1 cup chilled heavy whipping cream
  • ½ cup store bought lemon curd at room temperature (can be found with the jams and jellies)
  • FOR THE FROSTING:
  • 14 Tablespoons (1¾ sticks) unsalted butter at room temperature
  • 4-6 cups confectioners sugar
  • 7 Tablespoons whole milk
  • ½ teaspoon grated lemon zest
  • 2 Tablespoons fresh lemon juice
  • 1 Tablespoon St. Germain elderflower liqueur
  • FOR ASSEMBLY:
  • Assortment of fresh or crystallized flowers
  • Lemon slices
Instructions
  1. FOR THE CAKE: Preheat the oven to 300 degrees. Using 1-2 Tablespoons of unsalted butter, grease the three 8-9 inch cake pans and line the bottoms with parchment paper rounds. (If you only have 1-2 cake pans, cover batter and reserve at room temperature. Make sure the pans are cool before you reuse them. A simple rinse in cool water in the sink.) Place the granulated sugar in the bowl of a stand mixer or handheld electric mixer. Use your clean fingers to rub the lemon zest into the sugar until the sugar is aromatic and moist.
  2. Add the butter and beat on med-high speed for about 3 minutes, until the mixture is fluffy and light. Meanwhile, in a liquid measuring cup lightly whisk the eggs together with the vanilla extract and Kosher salt. Reduce the mixer speed to low and gradually add to the butter-sugar mixture until fully incorporated. Stop to scrape down the bowl.
  3. In a separate bowl, whisk together the flour and baking powder, then add half of it to the butter mixture. Beat on low speed until just combined, then add the milk and elderflower liqueur. Beat on low speed until well incorporated.
  4. Add the remaining flour and beat on low speed until no trace of dry flour remains, stopping to scrape down bowl as needed. Divide batter equally between prepared cake pans and smooth tops with offset or silicone spatula. If you use a kitchen scale, each pan should contain 10.5 ounces (300 grams) of batter.
  5. Bake pans on middle rack in oven for about 15-20 minutes or until the top of each cake layer springs back to the touch and the edges are lightly browned and pulling away from the sides of the pan. Cool cakes in pans for 15 minutes and then run a dull knife or offset spatula around the edges to release the layers. Invert onto a wire rack and peel off parchment paper from bottoms. Using a pastry or silicone brush, lightly brush the bottoms of the cake layers only with the elderflower cordial. Repeat 3-4 times allowing a few minutes in between applications for cakes to absorb the liquid. Stop applying the liqueur If the cakes start to break apart at all.
  6. If you need to reuse the pans to get three layers, wash and dry the pan(s) and repeat baking and brushing with the cordial.
  7. FOR THE FILLING: Pour the heavy cream into the bowl of a stand mixer fitted with balloon whisk attachment or use a handheld electric mixer. Beat on high speed until stiff peaks form. (To test, remove whisk attachment and invert, if the tip of cream flops over, you need to beat it longer. If if holds its shape, you're done.
  8. Use a silicone spatula to gently fold in half of the lemon curd by lifting cream from bottom of bowl and folding it over the curd, rotating the bowl as you work. Be careful not to deflate the cream too much in the process. Fold in the remaining curd. Cover the bowl with plastic wrap and pop it into the fridge until ready to assemble the cake.
  9. FOR THE FROSTING: Place the confectioners sugar in a large bowl and whisk to break up any lumps. Place the room temperature butter in the bowl of a stand mixer or electric handheld mixer and beat on low speed, gradually adding in 2 cups of the confectioners sugar. Increase speed to med-high until frosting is smooth and mixture is well combined, scraping down sides of bowl as needed. On med-low speed, add in the milk, beating until combined.
  10. On med-low speed, gradually add 2 more cups of the confectioners sugar and beat at low speed for at least 3 minutes until mixture is smooth. Add the lemon zest, juice and St. Germain and beat at low speed until incorporated. Continue adding more confectioners sugar to achieve desired consistency which can vary based on temperature of kitchen and softness of butter. The frosting needs to be thin enough to spread but thick enough to not run off the cake. Chilling the frosting in the fridge for 20-30 minutes will help it set up.
  11. TO ASSEMBLE THE CAKE: Place a dab of frosting in the center of a cardboard cake round, cake stand or plate, preferably with no rim. Place one cake layer in the center with the cordial-soaked side facing up.
  12. Using an offset or silicone spatula, spread half of the filling evenly over the entire first layer, making sure to spread it out to the edges as well. Place the next cake layer on top and repeat with the remaining filling. Top with the third cake layer.
  13. Place a small amount of frosting in a separate bowl for the crumb coat. This is the initial layer of frosting applied to the cake which helps to seal in the crumbs. Once the crumb coat is applied to the top and sides of the cake, place cake in fridge and allow it to set up for 20-30 minutes.
  14. Apply the remaining frosting to the cake and decorate with flowers and sliced lemons or however you prefer. Return cake to the fridge and allow frosting to set up for an additional 20-30 minutes. Because of the soft filling and frosting, this cake is best cut and served while still very cool, right out of the fridge. By the time everyone eats the cake it will have softened up and temperature will be just right.
