4 large eggs (separated)

¼ teaspoon salt
1 teaspoon vanilla extract
¼ cup vegetable oil

How to Make Coffee Sponge Cake
Prepare the Batter
Preheat your oven to 350°F (175°C). Grease and line the bottom of an 8-inch round cake pan (do not grease the sides to help the cake rise evenly).
In a large bowl, whisk together egg yolks, half of the sugar, oil, dissolved coffee, and vanilla extract until pale and creamy.
In another bowl, sift together cake flour and salt. Gradually fold the flour mixture into the egg yolk mixture until smooth.
Whip Egg Whites
In a clean bowl, beat the egg whites until foamy. Gradually add the remaining sugar and beat until stiff peaks form.
Fold & Bake
Gently fold the whipped egg whites into the batter in batches, being careful not to deflate the mixture. Pour the batter into the prepared pan and smooth the top.
Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool completely before removing from the pan.
