Instructions
- Step 1: Preheat your oven to 350°F (175°C). Grease your 9x13-inch baking pan with butter or line it with parchment paper for easy removal later.
- Step 2: In a large mixing bowl, beat the unsalted butter until creamy. Gradually add in the brown sugar and continue to beat until light and fluffy. Add the egg yolks, one at a time, mixing well after each addition. Stir in the vanilla extract.
- Step 3: In another bowl, whisk together the all-purpose flour and salt (if using). Gradually add this mixture to the butter and sugar mixture, alternating with the lukewarm milk. Start and end with the flour mixture. Mix until just combined.
- Step 4: In a clean bowl, beat the egg whites until stiff peaks form. Gently fold the whipped egg whites into the batter, being careful not to deflate them.
- Step 5: Pour the batter into the prepared baking pan. Bake in the preheated oven for 40-45 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
- Step 6: Once baked, remove the cake from the oven and allow it to cool in the pan for about 10 minutes. Then, transfer it to a cooling rack. Once completely cooled, dust the top with powdered sugar before serving, if desired.
Notes
- Ensure your eggs are at room temperature for the best mixing results.
- Gently fold in the egg whites to maintain the airy texture.
- Let the cake cool completely before slicing to avoid it being fragile.
