White Chocolate Macadamia Nut Cake

White Chocolate Macadamia Nut Cake.. A simple brown sugar buttermilk cake with white chocolate frosting, topped with salty Macadamia Nuts!

This is a White Chocolate Macadamia Nut Cake. The cake itself is a brown sugar buttermilk cake, topped with rich white chocolate frosting and salty chopped macadamia nuts. Salty, sweet and PRETTY!

Sometimes you just need a cake in your life.


My husband is a huge white chocolate macadamia nut guy.

I never used to like  nuts in my desserts…and I guess still am not COMPLETELY on board…but I have broadened my horizons in my old age.

And old people always like nuts in their desserts. It’s a fact.

So that brings me to now. Cake.

With nuts.

But don’t be scared…macadamia nuts are like the most girlie nuts out there. Even more than pistachios.

They’re like nuts for lightweights…not to be confused with geriatric-walnutty nuts.

Macadamia nuts are fresh and clean and pretty. They’re the most popular nut at the nut high school.


Ok, even if you aren’t, just leave off the dang nuts. It’s fine. But you’ll regret it, because the saltiness of the nuts on top the white chocolate frosting is major.

ANNNND the cake itself is a brown sugar buttermilk cake that totally rules.

Try it. White Chocolate Macadamia Nut Cake…

Like I said, the cake itself is a brown sugar buttermilk cake. It;s super good.

I actually buy  dry buttermilk and keep it in the fridge. It’s handy because I never have fresh buttermilk on hand.

Pour your batter into a greased 9×13…

When your cake is done it will look like this…

Meanwhile make your frosting.

Powdered sugar, of course…oh and butter. Duh.

Melted white chocolate…


Plop that frosting all up on there…

And just zhush it around…

Then grab some super salty macadamia nuts. And chop ’em up.

Add those all over the top…

I even got fancy and made a few white chocolate curls…and then quit because I was cussing too much. Those things are annoying.

Instead of curls sprinkle some white chocolate chips on top. Less cussing involved.

Then immediately eat.

I mean, you don’t HAVE to eat immediately, but you probably want to. And I won’t deny you that…

I have ZERO qualms with nuts in my dessert…
I could totally eat this whole thing right now. Your #eatallthefeelings donut post on IG yesterday totally hit home.
Anyhoo, gorgeous as always!

buttery brown sugar goodness!!! I must try this… have to swap out the nuts for something else- allergies 🙁 but I’m thinking crushed pretzels would be perfect with that luscious white chocolate frosting!

This cake looks darn delicious. I can take or leave nuts with my desserts but I am in love this white chocolate and macadamia nut combination.

The cake looks amazing! But, this statement threw me…….geriatric-walnutty nuts? I am no where near being “geriatric” and I Love LOVE walnuts. I had a handful of these heart-healthy and delicious nuts this morning. Walnuts are so good for you. Seriously, I would make this cake with walnuts and wouldn’t feel like I was a granny in her rocker. Plus, walnuts would add some healthy fats. That said, I do want to make this cake. It looks fantastic.

Macademia nuts are definetely the coolest of all the nuts 🙂

Wow excellent recipe I wasn’t too sure when the mixture looked curdly but the cake was very tender. I made it as a 2 layer cake with the icing and made pralined pecans as i didn’t have macadamian nuts on hand. With the chocolate curls the cake looked beautiful and tasted amazing!
Only down side it makes a really big cake so i would suggest half recipe or even 2/3 if not entertaining.
