How to Make Walnut Cake with Prunes

Making this walnut cake only requires a couple of homemade sponge cakes and a bit of light assembling. Below, find a quick overview of the recipe before you dive in.

  • Make the Sponge Cakes: Preferably the day before, prepare two sponge cakes.
  • Toast the Walnut Halves: On a baking sheet lined with parchment paper, bake the walnuts until they turn golden brown and set them aside to cool.
  • Make the Cake Cream: Using a stand mixer or a handheld electric mixer with a whisk attachment, beat the cream cheese and condensed milk together. Next, add in extra cold heavy cream and beat until it expands 3 times in volume.

  • Frost the Cake: Using the remaining cake cream, frost the entire outside of the cake. Next, decorate the sides and top of the cake with the remaining chopped walnuts.

Tips & Tricks

Below, find a couple of tips and tricks to help you make the best walnut cake with prunes.

  • Use softened cream cheese. Softened cream cheese is so much easier to incorporate into your frosting. Allow it to sit at room temperature for about 30 minutes before you get to baking.
  • Use extra cold heavy whipping cream. Heaving whipping cream needs to be extra cold to make fluffy cream. If yours is too warm, pop it in the freezer for up to 10 minutes before whipping it.
  • Whip up the sponge cake the day before. To cut down on prep time, prepare the sponge cake a day in advance, let it cool on a wire rack, and refrigerate it until you’re ready to assemble the cake.
  • Allow the cake to set in the fridge overnight. Letting the walnut cake set overnight in the fridge will not only allow it to develop its rich flavors, but will also help it keep its structure and shape.

Storing Walnut Cake

This walnut cake with prunes can be stored in the refrigerator or frozen whole for a rainy day. Here, find all the best tips and tricks to help you keep your walnut cake as fresh as possible.

  • Refrigerator: If you plan on eating the cake within a week, store it in an airtight cake container in the fridge. By keeping air out, you will maintain the cake’s freshness while also preventing it from soaking up smells in the fridge.
  • Freezer: You have two options when it comes to freezing – you can freeze the entire cake or a couple of leftover slices. If you’re freezing the entire cake, place it on a baking sheet lined with parchment and pop the entire baking sheet in the freezer. Once completely frozen, wrap the cake tightly in plastic wrap and freeze for up to 3 months. If freezing individual slices, simply wrap each one in plastic wrap. To thaw, place the cake in the fridge overnight.
