Overview of Recipe Content

What is Flourless Lemon Pistachio Cake?

This is a naturally gluten-free cake made with finely ground pistachios and almond flour instead of wheat flour. It’s rich yet light, sweetened with honey (or maple syrup), and flavored with fresh lemon zest and juice for that irresistible citrus brightness.

Why You’ll Love It

Gluten-Free & Naturally Sweetened — a wholesome treat everyone can enjoy.
Bright & Flavorful — the lemon cuts through the richness of the nuts beautifully.
Elegant but Easy — no fancy frosting, just a dusting of powdered sugar or a dollop of whipped cream.

What It Tastes Like

Think soft, nutty, melt-in-your-mouth cake with a tangy lemon finish. The pistachios give a subtle green hue and a delicate sweetness, while the almond flour adds that tender crumb.

Health & Seasonal Benefits

Pistachios and almonds are full of healthy fats and plant-based protein. Lemons bring vitamin C and a refreshing zing, making this a lovely spring or summer bake.

Ingredients

💚 1 cup shelled raw pistachios (unsalted, finely ground)
🌰 1½ cups almond flour
🍋 Zest of 2 lemons
🍋 ¼ cup fresh lemon juice
🍯 ½ cup honey or maple syrup
🥚 4 large eggs (separated)
🥄 2 tsp vanilla extract
🥄 1½ tsp baking powder (gluten-free if needed)
🧂 Pinch of salt

Tools You’ll Need

Food processor or high-speed blender (for grinding pistachios)
Mixing bowls
Electric hand mixer or stand mixer
Rubber spatula
9-inch round cake pan
Parchment paper

Substitutions & Additions

How to Make Flourless Lemon Pistachio Cake

Prep the Pan & Oven
Preheat oven to 350°F (175°C). Line a 9-inch cake pan with parchment paper and lightly grease.
Grind the Pistachios
Place pistachios in a food processor and pulse until they resemble fine crumbs (but not paste).
Mix the Dry Ingredients
In a large bowl, combine ground pistachios, almond flour, lemon zest, baking powder, and salt.
Whip the Egg Whites
In a clean bowl, beat egg whites until soft peaks form. This helps keep the cake airy.
Mix the Wet Ingredients
In another bowl, whisk together egg yolks, honey, lemon juice, and vanilla until smooth.
Combine & Fold
Add the wet mixture into the dry, then gently fold in the whipped egg whites until fully combined.
Bake
Pour batter into the prepared pan. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
Cool & Serve
Let cool in the pan for 10 minutes, then transfer to a wire rack. Serve plain, dusted with powdered sugar, or with fresh berries and whipped cream.

What to Serve with Flourless Lemon Pistachio Cake

Tips for Making It Perfect

Don’t over-grind the pistachios or they’ll turn into nut butter.
Make sure your egg whites are at room temperature for the best volume.
Use fresh lemon juice, not bottled — it makes a huge difference.

Storage Instructions

Room Temp: Store covered for up to 2 days.
Fridge: Wrap well and store up to 5 days.
