Zesty Lemon Pistachio Cake Recipe with Toasted Nuts

This soft and fluffy Lemon Pistachio Cake is a simple single-layer cake featuring a tender pistachio sponge made with olive oil and finished with a light, whipped lemon cream cheese frosting. Bright lemon zest and roasted pistachios give the cake a fresh, nutty flavor while the oil keeps the crumb moist and tender. The frosting is airy and tangy — a lighter alternative to traditional butter-heavy cream cheese frostings. This cake works year-round: it feels fresh in spring and summer, but the pistachios also make it festive for holidays. If you enjoy fruity sheet cakes, you might also like other lemon-and-berry combinations or pistachio-forward bakes.

WHY THIS RECIPE WORKS

• Soft, moist pistachio cake – the recipe yields a tender cake with a springy, moist crumb.
• Easy to make – a single-layer sheet or square cake is uncomplicated and keeps cleanup minimal.
• Fragrant lemon – lemon zest adds bright citrus notes that pair beautifully with pistachios.
• Olive oil base – olive oil complements the pistachios and lemon; any neutral oil can be used if preferred.
• Light cream cheese frosting – this frosting uses cream cheese and whipped cream (no butter) for a silky, flavorful finish.

INGREDIENTS FOR LEMON PISTACHIO CAKE

Below are the key ingredients and notes. The full ingredient list and quantities are included in the recipe card later in the post.

• All-purpose flour – unbleached all-purpose flour is ideal for a soft, spongy cake. Cake flour can be used, but bleached flours sometimes absorb more liquid and risk a drier texture.
• Oil – liquid oil keeps the cake soft and encourages an even rise. Olive oil works especially well with pistachios and lemon, though neutral oils like sunflower or canola are good alternatives.
• Pistachios – finely ground roasted pistachios provide both flavor and a natural green tint. Lightly toasting raw pistachios first enhances their aroma and taste.
• Granulated sugar – simple granulated sugar sweetens without masking the lemon and nut flavors.

• Egg – one large egg adds structure without overpowering the flavors.
• Pure vanilla extract – boosts and rounds the citrus notes; optional almond extract enhances the pistachio character.
• Full-fat plain yogurt – adds moisture and a touch of tang that complements the lemon.
• Matcha powder (optional) – optional for enhancing the green color and adding a subtle earthy note that pairs with pistachio.
• Lemon zest – zest from one lemon provides a bright citrus aroma; use up to a tablespoon for a stronger lemon profile.
• Milk – any milk works; whole milk gives the best richness for baking.

STEP BY STEP INSTRUCTIONS: HOW TO MAKE LEMON PISTACHIO CAKE

• STEP 1 — Infuse the sugar: Combine granulated sugar and lemon zest in a bowl and rub together until fragrant. This releases lemon oils and intensifies flavor throughout the batter.
• STEP 2 — Mix dry ingredients: Sift or whisk together flour, baking powder, baking soda, and salt into the lemon-infused sugar. Stir in the ground pistachios (and matcha, if using).
• STEP 3 — Combine wet ingredients: Whisk together egg, oil, yogurt, vanilla, and milk until smooth.
• STEP 4 — Combine wet and dry: Make a well in the dry ingredients, add the wet mixture, and gently whisk or fold until just combined. Avoid over-mixing.
• STEP 5 — Bake: Pour batter into a prepared pan, bake until golden and a skewer inserted in the center comes out clean. Cake should spring back lightly when pressed. Cool 20 minutes in the pan, then transfer to a rack to finish cooling.
• STEP 6 — Make the frosting: Beat softened cream cheese until smooth. Add 2 tablespoons of cream and mix until lump-free, then beat in the remaining cream until soft peaks form. Gradually add sugar until thickened to a spreadable texture, then mix in lemon juice and vanilla (and a drop of almond extract, if desired). Spread the frosting on the cooled cake and sprinkle with crushed pistachios before serving.

EXPERT BAKING TIPS FOR LEMON PISTACHIO CAKE

• Infuse sugar with zest: Rubbing sugar with lemon zest extracts essential oils that distribute citrus flavor more evenly in the batter.
• Use room-temperature ingredients: Bringing ingredients to similar temperatures helps them combine smoothly and avoids overworking the batter.
• Roast raw pistachios: Toasting pistachios in a dry pan brings out their aroma and deepens the flavor before grinding.
• Optional sifting: Sifting dry ingredients can reduce mixing time and lower the risk of overdeveloping gluten.
• Don’t over-mix: Stop mixing once the flour is incorporated to keep the cake light and tender.
