Coconut Marble Bundt Cake

Take moist coconut cake and swirl in some chocolate and you’ve got Coconut Marble Bundt Cake. Dress it up with some chocolate ganache for dessert or have it plain with coffee.

Some friends of mine invited me to their wedding anniversary and they asked me to bring a cake. They’re Pakistani refugees and their story is enough to bring tears to your eyes.

The parents have been married for about 30 years so this is indeed a special anniversary! I have a sweet little Wilton heart bundt pan (affiliate link) so thought it would be fun to make them a cake in that.

A woman and a man are seated next to each other facing the camera. There is a whole coconut marble bundt cake in front of them and they are slicing it together.

I’ve also been wanting to make another chocolate and coconut cake for a while. Last time I made a chocolate cake with coconut filling so I thought I’d invert it this time.

On the first attempt I made separate batters, put the chocolate on top and swirled with a knife. But when I inverted the cake, all  the chocolate stayed in a lump on the bottom. It was good but not exactly a coconut marble bundt cake.

The other issue for me was that the chocolate ganache was so thick it covered up the hearts. Not that anyone really minded.

My second swirling method was actually a mistake. I pulled out a cup of the coconut batter to add the chocolate to and then got distracted. In my distraction, I dumped the cocoa powder in the wrong bowl.

This is a slice of coconut marble bundt cake with no ganache. The cut side is facing the front of the photo. There are several chocolate swirls at the bottom and top of the slice.

Have you ever done that? It’s the story of my life so I’ve learned lots of ways to fix things. I had a choice. Mix it in or scoop as much out as possible. I opted for the latter.

I got most of it out (with a little batter to boot but there was already chocolate in my coconut. So I thought why not just swirl the chocolate batter in before putting it in the pan.

The result was a much more marbled cake – exactly what I wanted. I kept the second cake plain and took it to morning tea with my friends.

Coconut mostly adds texture to this cake. I used coconut milk in the batter and the ganache to up the coconut flavor but it’s still mild. If you want more coconut, add some coconut flavor or coconut rum. You can always substitute whole milk or (better) cream for the coconut milk for a more vanilla flavored cake.
