Marble Sponge Cake (Banh Bong Lan Marble) Recipe

Marble Sponge Cake (Banh Bong Lan Marble)

Ingredients
1 cup Cake Flour
6 Large Eggs
1/2 cup Sugar
1/3 cup Chocolate
1/4 cup Canola Oil
1/4 cup Orange Juice
1/8 tsp. Salt

Separate 6 Large Eggs.  Add 1/8 tsp. Salt into the Egg Whites and beat. Slowly add in 1/2 cup Sugar.  Beat until it reaches stiff peaks.
Set aside.

Take the Egg Yolks and add in 1/4 cup Orange Juice.  Then add in 1/4 cup Canola Oil. Sift in 1 cup Cake Flour.  Mix until well combined.

Fold in the Egg Whites.  Scoop about 1/3 of the batter into a separate bowl.

Melt 1/3 cup Chocolate.  Place the chocolate bowl in hot water.  The chocolate will melt within 1-2 minutes.

Add in the melted chocolate into the 1/3 batter.  Fold the chocolate into the batter.

Line a 9 inch baking pan with parchment. First pour about half of the regular batter.  Then pour in the chocolate batter and the rest of the regular batter on top.
Using a stick, swirl the batter.  This will help make chocolate swirls inside the cake.
Give it a tap to remove bubbles.  Place in oven and bake at 350 degrees F. for about 30-35 minutes or until a toothpick comes out clean.

After it finish baking, remove the cake out of the baking pan to avoid shrinking.

Let it rest for a bit and cut a slice to enjoy.
