This white chocolate and pistachio cake has become my signature celebration dessert, combining the delicate sweetness of white chocolate with the nutty richness of pistachios in three perfect layers.
I first created this for my best friend's birthday when I wanted something elegant yet unique. The combination of pistachios and white chocolate received so many compliments that it's now requested at every family gathering.
Ingredients
- Unsalted butter: Provides the rich foundation for both cake and buttercream while letting the star flavors shine
- Caster sugar: Gives the perfect sweetness and helps create that light tender crumb
- Medium eggs: Provide structure and moisture to balance the richness
- Self raising flour: Ensures a beautiful rise without complication
- Whole milk: Adds necessary moisture and fat content for a tender crumb
- Pistachios: Bring a wonderful nutty flavor and beautiful color contrast throughout the cake
- White chocolate chunks: Melt slightly during baking creating pockets of sweet creaminess
- Icing sugar: Sifted creates that perfectly smooth buttercream texture
- Vanilla extract: Enhances all the flavors while adding subtle warmth
Step-by-Step Instructions
- Preparation:
- Preheat your oven to 180C/160C Fan/350F and prepare three 8 inch cake tins by greasing and lining them with parchment paper. This ensures your cakes will release perfectly once baked.
- Creaming Stage:
- Cream together the unsalted butter and caster sugar for a full 5 minutes until noticeably lighter in color and fluffy in texture. This incorporates air which is crucial for a light cake crumb.
- Egg Incorporation:
- Add the eggs one at a time mixing well between each addition. If the mixture looks like it might curdle add a spoonful of flour to stabilize it. This gradual approach ensures a smooth emulsion.
- Combining Dry and Wet Ingredients:
- Add the self raising flour and whole milk then whisk for exactly one minute on medium speed. This limited mixing activates just enough gluten for structure while keeping the cake tender.
- Adding Mix Ins:
- Gently fold in the chopped pistachios and white chocolate chunks using a spatula with a light hand. Overmixing now would develop too much gluten leading to a tough cake.
- Baking Process:
- Divide the batter evenly between the three prepared tins and bake for 30 to 35 minutes until golden and a skewer inserted comes out clean. The cakes should spring back when lightly touched.
- Cooling Phase:
- Allow the cakes to cool in their tins for exactly 5 minutes before carefully transferring to wire racks to cool completely. This prevents condensation making the cake soggy.
- Buttercream Preparation:
- Melt the white chocolate gently over a pan of simmering water being careful not to let any water touch the chocolate which would cause it to seize. Set aside to cool but not harden.
- Buttercream Base:
- Beat the butter icing sugar and vanilla until extremely light and fluffy. This can take 3 to 4 minutes but creates the perfect base for your white chocolate addition.
- Chocolate Incorporation:
- Gradually add the cooled melted white chocolate to the buttercream mixing continuously. Continue beating for a full 5 minutes to achieve that silky light texture.
- Assembly:
- Spread buttercream between each cake layer ensuring they are level and stack evenly. Use a piping bag fitted with a 2D closed star tip to create decorative swirls on top.
- Final Decoration:
- Sprinkle the chopped pistachios over the top focusing on the center for a beautiful color contrast against the white buttercream.

White chocolate and pistachio is one of those magical flavor combinations that I discovered by accident. I was running low on dark chocolate for my usual cake recipe and substituted white chocolate with some pistachios I had in the pantry. The resulting flavor was so much more sophisticated and interesting that it became an instant favorite.
Storing Your Cake
This cake will maintain its wonderful texture and flavor for 3 to 4 days when stored properly. Keep it in an airtight container at room temperature away from direct sunlight. The butter content helps keep the cake moist even days after baking making it perfect for preparing ahead for events or enjoying leftovers throughout the week.

Scaling Options
If you prefer a smaller cake you can easily reduce the recipe by a third to create a two layer cake instead. Alternatively use the full recipe to create two thicker layers which will require slightly longer baking time approximately 40 to 45 minutes. Always use the skewer test to confirm doneness regardless of the pan size you choose as oven temperatures can vary considerably.
Flavor Variations
While the pistachio and white chocolate combination is stunning there are several delicious variations worth trying. Replace the pistachios with toasted hazelnuts for a praline like flavor that pairs beautifully with the white chocolate. For a fruity twist add some dried cranberries or cherries to the batter which will provide a wonderful tart contrast to the sweet cake. You could also infuse the milk with cardamom before adding it to the batter for a subtle aromatic dimension that complements both the pistachios and white chocolate.
