Preheat oven to 350 F.

In a mixing bowl, whip egg whites to soft peaks then slowly add sugar while whipping egg whites to stiff peaks and set aside.

In another bowl, add softened butter, brown sugar and vanilla extract and blend.

Add eggs and egg yolks to butter mixture and blend.

In another bowl, add flour, salt and baking powder and stir together well.

Add flour mixture to butter and egg mixture and blend well.

Add egg whites and fold them into your batter until they are well incorporated and you can’t see any egg whites.

Lay parchment paper over a cookie sheet and spray with non-stick spray.

Pour batter over the cookie sheet, it is ok if it doesn’t cover the whole pan, just try your best to spread it out over most of the pan in a large square.

Bake for 10 minutes or until cake is risen and feels cooked when pressed gently with finger.

Remove from oven and allow to cool.

If you are familiar with the towel method for rolling up the warm cake and letting it cool with the towel in place of the filling while it cools, you can do that. However, I don’t always love this method because it think it causes issues when you unroll to fill it but if you are comfortable with this method then do it. Otherwise, let the cake cool before adding filling.

While cake is cooling, whip the cream, powdered sugar, vanilla extract and salt together until whipping cream can form stable peaks, careful not to over whip or break cream.

Make a small slice on the end of your roll that will become the center for your roll, cut about 1 inch in from the edge and 3/4th the way through the depth of the cake. It will help you get a tighter swirl and roll.

Add the dulce de leche or caramel sauce onto cake, then whipped cream, (preserve some whipped cream mixture for the top of the roll), and sliced bananas to the unrolled top of the cake and then gently roll the cake into a roll.

Place seam side down so it doesn’t unroll.

cover the top of the roll with the additional whipped cream and sprinkle with graham crackers and drizzle caramel sauce if desired.

Slice and enjoy!
