This indeed is a scrumptious cake. The only thing I did differently was use fresh grapefruit as opposed to canned grapefruits. Try it!

What to do with all this grapefruit from our beautiful Texas Ruby Red grapefruit tree? I made this recipe using fresh grapefruit for a Christmas cake!! I didn't use food coloring in the frosting, but I used a bundt cake pan, frosted the cake with the white frosting, and put the grapefruit in the center (spent all day peeling grapefruit, but it was worth it all. I drained the grapefruit then put the grapefruit sections in the center of the cake and topped it off with a sprig of holly! It's so festive! Everyone wants a piece before dinner...but too bad...they have to wait! Thank you Paula for a fun and different cake! It's so light and complements are Texas Ruby Reds perfectly! Plus it's the perfect treat after a heavy dinner (to eat much later in the evening of course.

I have noticed that the recipe here on the website says to use 1 1/2 cups of flour but Paula, on the show, says only 1/2 cup. Does anyone know which is actually correct?
