Method
Preparation
- Preheat your oven to 350°F (175°C). Grease a 9×9-inch baking dish and set aside.
- Separate the egg whites and yolks into two bowls.
Mixing the batter
- With an electric mixer, beat the egg whites until soft peaks form, slowly add 1/4 cup of sugar until glossy stiff peaks hold.
- In another bowl with the yolks, whisk together the remaining 3/4 cup sugar and lemon zest until fragrant, then add lemon juice, melted butter, milk, and vanilla; whisk until smooth.
- Sift or whisk in flour, baking powder, and salt into the yolk mixture until combined.
- Gently fold in one-third of the beaten egg whites to lighten the batter, then fold in remaining egg whites carefully.
Baking
- Pour the batter into the prepared dish and smooth the top. Bake for 35-45 minutes until the top is golden and a toothpick inserted comes out mostly clean.
- Let cool for about 20-30 minutes before serving.
Serving Suggestions
- Serve warm with a dusting of powdered sugar or chilled with fresh berries.
