Pineapple Coconut Tunnel Cake

A couple of weeks ago, we attended my husband’s family reunion.  I was asked to “make cookies or something.” Well, I already knew of a few doing that, and I wanted to experiment.  I literally dreamt this cake up early one morning.

I love bundt cakes.  Their presentation is just so pretty!

I have told you before, that my taste for coconut has gradually grown into where I can actually say that I don’t mind it anymore.  I have made my husband’s favorite Coconut Macaroon Tunnel Cake so many times, I can practically make it in my sleep.  He was always happy to eat the coconut tunnel in the middle and I ate the chocolate cake around the outside.  I think when I actually decided that coconut is actually pretty darn good, was when I mastered the Coconut Cream Pie.  I am not going to lie, this thing is just plain delicious.

I love pina coladas, the combination of coconut and pineapple — I decided that this idea would make a wonderful cake, and darn it if I wasn’t right on!

This cake starts with a yellow box mix, but the water is replaced with pineapple juice.  The scent of the cake is marvelous when it’s in the mixer.  Oh my!

Then I added a tunnel of coconut macaroon to the center before baking, it’s topped with a pineapple glaze and a generous dusting of coconut.  The results? Two thumps WAY up!

Before I share the recipe, I thought I would share this photo from the reunion.  The grillers:

  1. This cake looks amazing and sounds so delicious! I LOVE coconut and will be pinning this to my coconut Pinterest board and sharing over on FB and Twitter. I can’t wait to try this one! I would be honored if you would stop by and share it over at my link party, Celebrate it Sunday!

  2. Prepare filling? How about some directions? Do the egg whites need to be whipped? Everything mixed all at once? Sugar and egg whites beaten first? You have to give some sort of directions.
