Pistachio, olive oil, and espresso are all excellent on their own — but combined they create a truly memorable Pistachio Olive Oil Cake with Espresso Cream. The pistachio brings a gentle nuttiness, the extra-virgin olive oil adds a fruity richness, and the espresso contributes a pleasant bitter edge. The result is a layered cake that’s flavorful without being overly sweet: rich in taste yet light in texture, the kind of dessert where one slice never feels like enough.
The Four Components of This Cake
This cake is made from four complementary layers. Each component contributes its own texture and flavor so the finished dessert is balanced, light, and nuanced rather than cloyingly sweet.
1. The Pistachio Crémeux
At the heart of the cake is a pistachio crémeux: a silky custard made from roasted pistachios, cream, and egg yolks. It’s smooth and nut-forward, with a texture between pudding and ganache. A small amount of gelatin gives the crémeux structure without weighing it down. Prepare it first so it can chill and set before assembly — it becomes the pale green layer you see when the cake is sliced.
2. The Olive Oil Cake
The cake itself is a chiffon-style olive oil sponge. Olive oil keeps the crumb moist while beaten egg whites provide lift, so the layer stays airy and tender — a perfect foil for the richer fillings. Using a good extra-virgin olive oil gives a subtle fruity note that comes through in every bite.
3. The Espresso Mascarpone Cream
The espresso mascarpone cream unites the flavors. Think of it as a coffee-forward whipped cream reminiscent of tiramisu filling: mascarpone adds richness, espresso powder gives bright coffee notes, and a touch of vanilla rounds everything out. The texture is light and silky, providing contrast to the denser pistachio layer.
4. The Cocoa Finish
A final dusting of cocoa powder adds a hint of bitterness that balances the creams and highlights the espresso. It’s a simple finishing touch that gives the cake a polished, slightly rustic appearance.

Instructions
Pistachio Crémeux
-
Make a pistachio paste by blending roasted pistachios with the neutral oil in a food processor until smooth and glossy, scraping down the sides as needed. The texture should resemble natural nut butter.
-
Sprinkle gelatin over the cold water in a small bowl and let it bloom for at least 5 minutes.
-
Heat the heavy cream and milk in a saucepan over medium heat until steaming.
-
Whisk the egg yolks and sugar until slightly pale. Temper the yolks by slowly whisking in about half the hot cream, then return the mixture to the saucepan.
-
Cook the custard over medium heat, stirring constantly, until it thickens enough to coat the back of a spoon (about 180°F). Do not boil.
-
Remove from heat, dissolve the bloomed gelatin into the custard, then whisk in the pistachio paste until smooth.
-
Transfer to a bowl, press plastic wrap directly on the surface, and refrigerate for at least 3 hours to set.
Chiffon Cake
-
Whisk together the flour, baking powder, and salt.
-
In a separate bowl, whisk the yolks with brown sugar, olive oil, and water until combined.
-
Sift the dry ingredients into the yolk mixture and whisk until smooth.
-
Whip the egg whites with cream of tartar to soft peaks, then gradually add the sugar and continue to whip to stiff, glossy peaks.
-
Fold one-third of the meringue into the yolk mixture to lighten it, then gently fold in the remaining meringue until incorporated.
-
Pour the batter into an ungreased 8″ round pan and bake at 325°F for about 30 minutes, until golden and springy to the touch.
-
Drop the pan from about 6 inches after removing from the oven to help prevent sinking. Cool completely before releasing from the pan.
Assembly of Cake & Pistachio Cream Layer
-
Slice the cooled cake layer in half horizontally.
-
Line an 8″ cake ring or pan with plastic wrap, leaving long “handles” so you can lift the finished cake out easily.
-
Place one cake half in the bottom with the cut side up.
-
Spread the chilled pistachio crémeux into an even layer over the cake.
-
Top with the remaining cake layer, press gently, and chill in the refrigerator for about 2 hours to set.
Espresso Cream
-
In a large bowl, combine mascarpone and heavy cream and beat on medium until combined, about 30 seconds.
-
Add sugar, salt, vanilla paste, and instant espresso powder. Beat on medium-high until soft peaks form, about 1–2 minutes. Stop as soon as soft peaks form to avoid splitting the mixture.
Final Assembly
-
Spread the espresso mascarpone cream evenly over the chilled cake so the top is flat. Cover with plastic wrap and let it set in the refrigerator for at least 1 hour.
-
Dust the top with cocoa powder just before serving and lift the cake from the pan using the plastic handles. Slice and enjoy.
