Ingredients
For the Cake:
- 1 cup butter at room temperature
- 2 cups white sugar
- 4 large eggs at room temperature
- 1 cup whole milk or nut milk
- 1 tablespoon lemon extract
- 2 ⅔ cup cake flour
- 3 teaspoon baking powder
- 1 teaspoon kosher salt
For the Swiss Meringue Buttercream
- 4 egg whites
- 1 ½ cup granulated sugar
- 1 ½ cup unsalted butter at room temp
- 1 teaspoon vanilla extract
- 1 teaspoon almond extract
- ½ teaspoon sea salt
- Peeled and sliced citrus for topping
Instructions
For the Cake:
- Preheat your oven to 350 degrees F. Prepare a 9x13 inch caeke pan with baking spray and line with parchment paper.
- In a large mixer, cream together the butter and sugar for 2-3 minutes until light and fluffy. Add the eggs, one at a time, until fully combined. Add the milk and lemon extract and mix on low until just incorporated.
- In another small bowl, sift together the cake flour, baking powder and salt. Add the dry ingredients to the wet ingredients and mix until you have a smooth batter. Pour the cake batter into the prepared baking pan and bake for 30 minutes.
- Remove the cake from the oven and let cool completely before frosting.
Cup of Yum
For the Swiss Meringue Buttercream
- Place egg whites and sugar in a metal bowl of a stand mixer. Place bowl over a pan of simmering water, not touching the water. Whisk or stir constantly until sugar is dissolved and mixture comes to approximately 160ºF.
- Immediately place the bowl on the stand mixer and whip on high using the whisk attachment until frosting has become thick and glossy, forming a stiff peak. Continue to whip frosting until the bowl feels room temperature to the touch, a total of about 10 minutes.
- Switch the whisk attachment to the paddle attachment. With the mixer on low, drop in butter, 1 tablespoon at a time, beating until smooth after each addition. If frosting appears curdled or clumpy at any time, increase speed to medium-high and beat until smooth.
- Once all of the butter has been incorporated, mix in extracts and pinch of salt. If needed, continue beating until smooth.
- Swoop and dollop the Swiss Meringue Buttercream on top of the cooled cake and add the sliced citrus on top
Notes
- For the most attractive citrus, I recommend carefully cutting all the peel away from the whole fruit, and then thinly slicing along the equator.
