I’ve been teasing you with this cake over on Instagram for awhile now and I’m so excited to finally share the recipe here on the blog. It’s December so I don’t need to bore you with my 101 reasons why this recipe is so long overdue. The list is about as long as a five year old’s Christmas list for Santa Clause. We are all in the same boat, navigating ourselves the best we can through the organized chaos that is the holiday season. I am busy. You are busy. We are all waaayyy too busy. Which is why I’m going to keep this post short and sweet, just like this Hazelnut Cake with Chocolate Ganache.


This cake is a lazy-cake-girl’s dream. One layer, no decorating skills required and it looks so peerrrdy! Check. Check. Annddd check. If you are a fan of hazelnuts, this cake is for you! I’m personally loving hazelnuts at the moment and and you’ll see me adding them to lots of goodies like hazelnut chocolate chunk cookies and hazelnut toffee cinnamon rolls. HELLO!! But back to this cake. It is moist and fluffy, which are qualities I always want from a slice of cake. This 8 inch golden brown beauty is made with both cake flour and hazelnut flour which gives it the most delightful, nutty texture. And the pile of hazelnuts and chopped dark chocolate on top adds the perfect bit of crunch with every bite. And can we just take a minute to oooh and aaahh that fluffy cloud of freshly whipped cream. I just want to dive right into it.



The beauty of this cake is that it’s a single layer cake. No fussing around with leveling layers or spending time fretting about perfectly frosted sides. It almost feels like cheating because this cake is so simple to make but it’s sooo good! The thick layer of chocolate ganache gives it just the right amount of fancy. Perfect for a dinner party or just a cozy night in when you have a hankering for a little something special.


As promised, this post is no frills, no fuss, all sweet! Go make this cake people. Please excuse me while I go polish off the last slice.

Happy Baking!

  • 1/2 cup heavy cream
  • 1/2 cup dark chocolate, chopped (I use 70% cocao)

For Whipped Cream

  • 1 cup heavy cream
  • 1 TBSP powdered sugar to sweeten if desired


For Cake

  1. Preheat oven to 350 degrees.
  2. Line bottom of an 8 inch round cake pan with parchment paper, spray with non-stick cooking spray.

  4. In a standing mixer using a whisk attachment, beat egg whites on medium-high speed until soft peaks form.
  5. Scrape the egg whites into a separate bowl and set aside.
  6. Next, in bowl of stand mixer mix together egg yolks, oil, and vanilla until combined.
  7. Add flour mixture and mix on low until smooth.
  8. Gently fold in egg whites with a rubber spatula until almost combined. Add the rest of the egg whites and combine until no whites remain in the batter.

For Chocolate Ganache

  1. Heat heavy cream over medium heat in a small saucepan. Be careful not to bring to a boil or scorch the cream.
  2. Place chopped chocolate in a medium, shallow bowl.
  3. Once cream reaches a simmer, remove from heat and pour over the chocolate.
  4. Let sit for 5 minutes and then stir to fully combine.
  5. Let sit for 5-10 minutes to thicken and then pour over top of cake.
  6. Let sit for a few minutes to partially set and then carefully spread freshly whipped cream over the top of the ganache with an offset spatula, being careful not to smear the chocolate.

For Whipped Cream

  1. Add heavy whipping cream and powdered sugar to the bowl of a stand mixer with whisk attachment. Beat on high until soft peaks begin to form. Do not over mix.

      Yes, however the cake can get a bit dry since it is gluten free so this particular cake is best eaten the day of. The ganache can be made ahead but it will firm up as it cools which will make it a bit thicker when it comes time to pour it on the cake. If you do make it ahead, be sure to top it with whipped cream just before serving for best results.

    How come all the ingredients are written twice. How do I understand that? Do I take flour twice, eggs 2 times? Please help
