Lemon Pistachio Cake with Lovely Lemon Frosting Recipe
Introduction
This Lemon Pistachio Cake is a bright and nutty treat perfect for any occasion. The moist almond and oat flour base pairs beautifully with zesty lemon frosting and a touch of fruity jam, creating a delightful balance of flavors and textures.

Ingredients
- 1 cup (135g) roasted shelled pistachios*
- 1 ½ cups (169g) fine blanched almond flour
- 1 cup (95g) oat flour, gluten free if desired
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon kosher salt
- Zest from 2 large lemons
- 1 cup (200g) granulated sugar (organic cane sugar recommended)
- 4 large eggs, at room temperature
- ½ cup (113g) plain or vanilla whole-milk Greek yogurt
- ¼ cup (50g) fresh squeezed lemon juice
- 1 teaspoon almond extract
- 1 batch Lovely Lemon Frosting (see recipe link below)
- 6 tablespoons low sugar strawberry jam (or blueberry jam as a substitute)
- Strawberries or berries of choice, for topping
Instructions
- Step 1: Preheat your oven to 350°F. Line the bottom of three 6-inch round cake pans or two 8-inch round pans with parchment paper rounds and spray the parchment and pan sides with nonstick cooking spray. Parchment paper is essential to prevent sticking.
- Step 2: Prepare the pistachios by placing 1 cup into a food processor and processing on high until finely ground, about 30 seconds to 1 minute. Set aside 1 to 2 tablespoons for decorating later.
- Step 3: In a large bowl, whisk together the ground pistachios (excluding the reserved amount), almond flour, oat flour, baking powder, baking soda, and salt.
- Step 4: In a separate bowl, combine the sugar and lemon zest. Rub the zest into the sugar using your fingers for about 1 minute to infuse flavor. Add the eggs, Greek yogurt, lemon juice, and almond extract. Whisk until smooth.
- Step 5: Gradually add the dry ingredients to the wet, mixing with a wooden spoon until the batter is smooth. Optionally, add 1-2 drops of dye-free green food coloring for a fun color.
- Step 6: Divide the batter evenly among the prepared pans and smooth the tops with a spatula. Bake for 18-25 minutes (for 8-inch pans) or 22-28 minutes (for 6-inch pans) until a toothpick inserted comes out clean or with a few crumbs.
- Step 7: Allow cakes to cool completely before removing them from the pans. Cakes should be at room temperature before frosting. They can be made a day ahead and refrigerated, wrapped well.
- Step 8: Prepare the Lovely Lemon Frosting according to the recipe here.
- Step 9: To frost, place 1-2 tablespoons of frosting on your cake stand and spread. Carefully invert a cake layer onto the stand, flat side up. Spread about ½ cup frosting evenly over the layer, then top with 3 tablespoons (6-inch cakes) or 6 tablespoons (8-inch cakes) of strawberry jam, leaving a ¼-inch border.
- Step 10: Repeat layering with remaining cakes and frosting. For three-layer cakes, frost the sides and top with about ½ cup frosting to create a crumb coat. Chill in the fridge for 15-20 minutes to firm the frosting.
- Step 11: After chilling, apply the remaining frosting smoothly over the cake. Garnish with the reserved ground pistachios and fresh berries just before serving.

Ingredients
Dry ingredients:
- 1 cup (135g) roasted shelled pistachios
- 1 ½ cups (169g) fine blanched almond flour
- 1 cup (95g) oat flour, gluten free if desired
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon kosher salt
Wet ingredients:
- Zest from 2 large lemons
- 1 cup (200g) granulated sugar (organic cane sugar recommended)
- 4 large eggs, at room temperature
- ½ cup (113g) plain or vanilla whole-milk Greek yogurt
- ¼ cup (50g) fresh squeezed lemon juice
- 1 teaspoon almond extract
For the cake assembly:
- 1 batch Lovely Lemon Frosting
- 6 tablespoons low sugar strawberry jam (substitute blueberry jam if preferred)
- Strawberries or berries of choice, for topping
Instructions
- Preheat and prepare pans: Preheat your oven to 350°F. Line the bottom of three 6-inch or two 8-inch round cake pans with parchment paper rounds and spray the parchment and sides of the pans with nonstick cooking spray. This prevents sticking and ensures easy release.
- Grind pistachios: Place 1 cup pistachios into a food processor and pulse on high for 30 seconds to 1 minute until finely ground. Reserve 1 to 2 tablespoons for decorating the finished cake.
- Combine dry ingredients: In a large bowl, whisk together the ground pistachios (minus reserved), almond flour, oat flour, baking powder, baking soda, and kosher salt.
- Prepare wet ingredients: In another large bowl, rub the lemon zest into the sugar with your fingers for about 1 minute to release the lemon oils. Add the eggs, Greek yogurt, lemon juice, and almond extract, whisking until smooth and well combined.
- Mix batter: Add the dry ingredients to the wet ingredients, stirring with a wooden spoon until smooth. Optionally, add 1-2 drops of dye-free green food coloring for a festive look.
- Bake the cakes: Divide the batter evenly among the prepared pans and smooth the tops with a spatula. Bake 18-25 minutes for 8-inch pans or 22-28 minutes for 6-inch pans, until a skewer inserted comes out clean or with a few moist crumbs. Cool completely before removing from pans. Cakes should be at room temperature before frosting.
- Make frosting: Prepare the Lovely Lemon Frosting as per recipe instructions.
- Assemble the cake: Place 1-2 tablespoons of frosting on the cake stand and spread out to anchor the bottom layer. Remove cakes from pans by running a butter knife around edges and inverting them onto the stand with the flat side up. Spread about ½ cup frosting on the first layer, then top with 3 tablespoons (for 6-inch cakes) or 6 tablespoons (for 8-inch cakes) of strawberry jam, spreading to within ¼ inch of the edges. Place the next cake layer flat-side up and repeat the frosting and jam layering. If using three layers, top with the third cake layer.
- Crumb coat: Cover the entire cake with approximately ½ cup frosting, smoothing with a bench scraper or offset spatula while turning the cake stand, to create a thin, even crumb coat layer. Refrigerate for 15-20 minutes to firm up.
- Final frosting and decoration: After chilling, apply remaining frosting smoothly over top and sides for a neat finish. A slightly ‘naked’ look is fine. Dust reserved ground pistachios on top and add fresh strawberries or mixed berries in the center just before serving for freshness.
- Storage: Serve immediately or store the cake well-covered in the refrigerator for up to 5 days to maintain freshness.
