Vibrant Pistachio Raspberry Delight

This pistachio raspberry cake combines the nutty sweetness of pistachios with the bright tang of fresh raspberries for a showstopping dessert that looks as gorgeous as it tastes. The vibrant green layers studded with ruby-red berries create a feast for both the eyes and palate.

I first made this cake for my sister's garden party and the vivid colors matched the summer flowers perfectly. The guests couldn't believe the natural green color came solely from pistachios!

Ingredients

• Unsalted butter: 250g softened. Using room temperature butter is crucial for achieving that light, mousse-like texture in both cake and frosting
• Golden caster sugar: 240g. The superfine texture dissolves more readily than granulated for a smoother crumb
• Vanilla extract: 1 tsp. Enhances the nutty flavor without overwhelming it
• Large eggs: 4. Provide structure and richness to balance the dense nut flour
• Plain flour: 150g. Creates structure while allowing the pistachio flavor to shine
• Baking powder: 2 tsp. Gives the perfect rise despite the weight of the ground nuts
• Fine sea salt: ¼ tsp. Amplifies the sweetness and nutty flavors
• Ground pistachios: 100g. Opt for Persian pistachios for the most vibrant green color
• Pistachio cream: 2 tbsp. Intensifies the nutty flavor in the buttercream
• Raspberry jam: 3 tbsp. Choose a good quality jam with whole fruit pieces for best flavor
• Fresh raspberries: 250g. Look for plump berries with deep color and sweet aroma

Step-by-Step Instructions

Prepare Your Equipment:

Preheat oven to 160°C fan or 180°C conventional. Thoroughly grease two 20cm round cake tins and line with baking paper. Taking time with this step prevents sticking and ensures even baking around the edges.

Create The Butter Base:

Beat softened butter and caster sugar together for a full 3-5 minutes until noticeably lighter in color and texture. This extended mixing incorporates air that creates the cake's tender crumb. The mixture should look almost whipped before proceeding.

Incorporate The Eggs:

Add eggs one at a time, beating thoroughly between each addition until completely smooth. This gradual approach prevents curdling and maintains the air bubbles essential for a light texture. The mixture should look glossy and well-combined.

Add Dry Ingredients:

Sift flour and baking powder together before gently folding in with the salt and ground pistachios. Use a light hand and stop mixing the moment everything is incorporated to avoid developing gluten that would toughen the cake.

Bake To Perfection:

Divide batter evenly between tins and smooth the tops. Bake for approximately 35 minutes until a skewer comes out clean. The tops should spring back when lightly pressed, and the edges will just begin pulling away from the sides.

Cool Properly:

Allow cakes to cool in tins for 15 minutes before transferring to a wire rack to cool completely. This gradual cooling prevents the cakes from sinking in the middle or becoming gummy from trapped steam.

Prepare Buttercream:

Beat softened butter until very pale before gradually adding sifted icing sugar. Continue beating until noticeably increased in volume. Add pistachio cream, salt and lemon juice, adjusting lemon to taste for balanced sweetness.

Assemble The Cake:

Place one cooled cake layer on a serving plate. Pipe or spread half the buttercream in an even layer, then carefully spread raspberry jam, staying slightly away from the edges. Top with second cake layer and remaining buttercream.

Apply Finishing Touches:

Decorate with fresh raspberries, chopped pistachios and mint sprigs, arranging them artfully for maximum visual impact. The contrast between the green cake, creamy frosting and bright red berries creates a stunning presentation.

Pin it

The first time I served this cake, my nephew became fascinated with the green color, demanding to know how I managed to hide vegetables in a dessert! The natural coloring from the pistachios has turned many skeptics into believers that vibrant food colors can come from nature rather than artificial sources.

Storage Solutions

This cake maintains its flavor and texture beautifully for up to three days when stored in an airtight container in the refrigerator. The key trick is removing it from the fridge about 20-30 minutes before serving to allow the buttercream to soften slightly, enhancing both flavor and mouthfeel. The cold temperature can dull the taste buds, so room temperature serving brings out the nuanced pistachio notes.

Freezing For Later

The components of this cake freeze exceptionally well separately. Wrap cooled cake layers tightly in plastic wrap, then aluminum foil, and freeze for up to three months. For the buttercream, store in airtight containers with plastic wrap pressed directly against the surface to prevent air exposure. When ready to assemble, thaw the sponges overnight at room temperature and let the buttercream warm up for several hours before re-whipping to restore its fluffy texture.

Seasonal Adaptations

While raspberries create a classic pairing with pistachios, this versatile cake welcomes seasonal variations. In summer, try fresh strawberries with strawberry jam for a more delicate sweetness. Early autumn brings the opportunity to use blackberries with blackberry preserves for a deeper, more complex flavor profile. During winter months, consider using poached pears with a thin layer of pear preserves for an elegant twist that maintains the cake's moisture while offering a sophisticated fruit alternative.

Cultural Background

This cake draws inspiration from Middle Eastern desserts where pistachios feature prominently in sweets like baklava and halva. The vibrant green color of pistachios holds cultural significance in many Persian celebrations, representing life and renewal. By pairing these traditional nuts with European cake techniques and British berry traditions, this recipe creates a delightful cross-cultural dessert experience that honors multiple culinary heritages while creating something distinctly modern.
