This fresh homemade Strawberry Cake is covered with a lemon Swiss Meringue Buttercream. The cake is incredibly moist and bursting with fresh strawberry flavor.
- For the cake:
- 4 ¾ cups (807.5g) fresh strawberries, sliced
- 2 ¼ cups (450g) plus 3 tablespoons (36g) granulated sugar, divided
- 3 ½ tablespoons (52.5g) fresh lemon juice, divided
- ¾ cup unsalted butter, at room temperature
- 6 large eggs whites (180g) at room temperature
- 1 ½ teaspoons (6g) vanilla extract
- 1 ½ cups (28g) freeze-dried strawberries
- 3 cups (375g) all-purpose flour
- 1 cup (100g) cake flour
- 1 tablespoon (15g) baking powder
- 1 ½ teaspoon (4.5g) salt
- 1 ½ cups (360g) whole milk, at room temperature
- For the frosting:
- 5 large egg whites
- 1 cup plus 2 tablespoons granulated sugar
- 1 lb (4 sticks) unsalted butter at room temperature
- 1 large lemon, zested
- For the cake: Slice the strawberries. You’ll need 2 ½ cups roughly chopped for the sauce and the remaining to be diced for the cake.
- In a medium-sized saucepan, combine 2 ¼ cups sliced strawberries, 3 tablespoons of sugar and 3 tablespoons of lemon juice. Cook over medium heat, stirring occasionally until reduced and slightly thickened, about 10 minutes. Remove from heat and cool completely.
- Preheat the oven to 350°F and generously grease and flour 3 8-inch cake pans. I suggest lining the bottom with parchment paper.
- In a large mixing bowl, combine the butter and remaining sugar (2 ¼ cups). Beat on medium speed using the paddle attachment until the butter it is light and fluffy, scraping the bowl as needed. This should take about 5 minutes.
- Add the egg whites, one at a time, ensuring that each one is well mixed before adding the next. Add the vanilla extract together with the last egg white.
- Use a food processor to grind the freeze-dried strawberries into a fine powder.
- In a medium-sized bowl, combine the powdered strawberries with the flour, cake flour, baking powder and salt. Gently whisk the ingredients together to combine.
- Next, slowly alternate adding the dry ingredients with the milk, starting and ending with the dry ingredients. Beat on medium speed until all of the ingredients are just combine.
- In a small bowl, combine the remaining 1 ½ cups (225g) of strawberries with the remaining lemon juice (½ tablespoon). Stir to combine and then stir the strawberries into cake batter. At this time, you should also add the cooked strawberries as well. Turn the batter from the bottom to the top to ensure all of the ingredients are well combined.
- Bake at 350°F for 28-35 minutes. Test your cake for doneness by inserting a toothpick into the center of the cake. If the toothpick comes out clean, you cake is done. After 15-20 minutes, run a knife around the outside edge of the cake and gently remove from the pan. Allow the cakes to cool completely on a wire rack.
- For the frosting: Combine the sugar and egg whites in your stainless steel mixer bowl (or any heat proof bowl). Attached your candy thermometer to the side of the bowl.
- Set your bowl over top of a pot with water, just enough to cover the bottom of the pot. You do not want the water to boil and touch the bottom of your mixing bowl. Heat the water on medium to medium-low heat.
- Combine the sugar and egg whites and stir (using your greaseproof spatula) constantly until the mixture reaches 140° F. This is the most important part; you do not want to egg whites to cook. I have read that you can have it be anywhere between 120° F – 160° F. When it reaches 140° F, the sugar should be dissolved in the egg whites. You can test this by placing a drop on your fingertips and rubbing them together. The mixture should be completely smooth.
- Place the mixing bowl on your stand mixer. Using the wire whisk attachment, beat the egg whites. Start on low and increase the speed to medium after 2 minutes.
- Beat for another 3 minutes on medium. At this point, your frosting should have turned white as the egg whites are whipped and the body of the meringue starts to form.
- After 5 minutes, increase the speed to high. You will notice that as you increase the speed, the body of your meringue will also increase. It will start to look glossy as the peaks begin to form. Beat for another 5 minutes.
- After you have beat the meringue for a total of about 10 minutes, the bottom of your mixing bowl should be cooled completely. Your SMB should look kind of like whipped cream. Scrape down all sides and bottom of the bowl.
- Turn your mixer down to medium-low. Slowly add your butter, about 1 tablespoon at a time, ensuring it is mixed well after each addition. Once you have added all your butter. Mix for another minute and scrape down the sides of the bowl.
- Switch to the paddle attachment and continue beating on medium to allow all the air bubbles to escape. In about 2-3 minutes the frosting is smooth. Lastly, fold in the lemon zest.
