Ingredients Needed
For the cake:
- 2 cups almond flour
- 1 cup granulated sugar
- 4 large eggs
- ½ cup melted butter or olive oil
- Juice of 2 lemons (freshly squeezed for the best flavor)
- Zest of 2 lemons (adds brightness)
- 1 teaspoon vanilla extract
- 1 teaspoon baking powder
- ½ teaspoon salt
- ½ cup chopped pistachios (plus more for garnish)
For the lemon syrup:
- ½ cup lemon juice (to add moisture)
- ⅓ cup granulated sugar (to enhance sweetness)
How to Make Irresistible Flourless Lemon Pistachio Cake
- Preheat the oven to 350°F (175°C). Prepare a round cake pan by greasing it and lining the bottom with parchment paper. This step makes removing the cake after baking a breeze.
- Whisk the eggs with the sugar in a large mixing bowl until they are well blended. This will create a smooth base for your cake.
- Stir in the melted butter (or olive oil), lemon juice, lemon zest, and vanilla. Mix until the ingredients come together beautifully.
- Incorporate the dry ingredients: Add the almond flour, baking powder, and salt. Stir until the batter is smooth and free of lumps.
- Add in the pistachios: Fold the chopped pistachios into the batter, ensuring they are evenly mixed throughout.
- Transfer the batter to the prepared cake pan, smoothing the top with a spatula.
- Bake the cake for 45–55 minutes, or until the edges are golden brown and the center feels set. A slight jiggle is fine—remember, it will firm up as it cools!
- Make the lemon syrup: While the cake is baking, combine the lemon juice and sugar in a small saucepan. Heat it gently until the sugar dissolves completely.
- Glaze the cake: Once the cake is out of the oven and still warm, drizzle the prepared syrup over it, allowing the cake to soak in the flavor.
- Garnish: Scatter additional pistachios on top of the glazed cake. Allow it to cool completely before slicing, so the slices set nicely.
How to Serve Irresistible Flourless Lemon Pistachio Cake
Serve this delightful cake plain or with a dollop of whipped cream or a scoop of vanilla ice cream. Pair it with a cup of tea or coffee for an afternoon treat. Garnishing with extra chopped pistachios not only enhances the look but also adds a nice crunch!
How to Store Irresistible Flourless Lemon Pistachio Cake
To keep your cake fresh, store it in an airtight container at room temperature for up to three days. If you want to keep it longer, you can refrigerate it for about a week. Just be sure to wrap it tightly in plastic wrap or foil to prevent it from drying out.
Tips to Make Irresistible Flourless Lemon Pistachio Cake
- Room Temperature Eggs: Using room temperature eggs helps create better volume when whisking.
