Step 1

Preheat oven to 350 degrees. Spray your bundt pan with non-stick cooking spray.

Step 2

Prepare cake mix as per box instructions. Set aside.

Step 3

In a separate bowl, with a fork quickly mix egg whites. Add the sugar and vanilla and mix again. Stir in coconut and flour.

Pour about ½ of the cake mix into your bundt pan. (see photo in blog post) Now spoon filling in a "tunnel" on top of the batter. Be careful not to let the filling touch the pan. Now pour and evenly cover the tunnel with the rest of the batter.

Step 5

Bake the cake for 45 minutes or until toothpick comes out clean.

Step 6

Cool in pan for 20-30 minutes and turn onto a plate to cool the rest of the way.
