Ingredients
Method
For the Cake:
- Preheat oven to 350°F and line a 9X13 cake pan with parchment paper.
- In the bowl of a standing mixer fitted with a paddle attachment (or a large bowl if using a hand mixer), sift in the flour, baking powder, salt and sugar. Whisk together and set aside.
- In a large bowl whisk together the egg whites, milk, vanilla, and sour cream; set aside.
- Beat butter into the dry mixture a tablespoon at a time until all the butter is incorporated. Then, beat in ½ of the wet mixture. (The batter should look dry and crumble at this point.) Add in the rest of the wet mixture and beat until combined.
- Pour batter into the prepared pan and bake for 45-55 minutes or until a tooth inserted comes out clean. Let the cake cool to room temperature.
For the Milk Mixture:
- In a large bowl whisk together the three milks. Once the cake is cooled, trim the sides and top and poke the cake with a fork. Drizzle the cake with the milk mixture and have it sit in the fridge for a few hours (ideally overnight.)
For the Meringue Frosting:
- In a heat-safe bowl, whisk the first four ingredients listed until fully combined.
- Set the bowl over a saucepan filled with a few inches of water that is starting to simmer. Whisk mixture constantly over the heat for about 5 minutes or until egg whites are warm to the touch and the sugar has dissolved.
- Remove the bowl from the heat and transfer mixture to a stand mixer fitted with a whisk attachment or a large bowl with a hand mixer. Mix on high speed until stiff glossy peaks form. About 5-7 minutes. Add vanilla and mix for 20 seconds to combine.
Assembly:
- Spread the lemon curd over the entire cake, then spread the meringue overtop of the lemon curd.
- Toasted meringue with a kitchen torch if desired, and enjoy!
