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 (recipe referenced)
- 6 tablespoons low sugar strawberry jam (or blueberry jam as substitute)
- Fresh strawberries or mixed berries, for topping
Instructions
- Preheat and Prepare Pans: Preheat your oven to 350°F (175°C). Line the bottoms of three 6-inch or two 8-inch round cake pans with parchment paper rounds and spray the paper and sides with nonstick cooking spray to prevent sticking.
- Process Pistachios: Place 1 cup of roasted shelled pistachios into a food processor and pulse on high for 30 seconds to 1 minute until finely ground. Reserve 1 to 2 tablespoons of the ground pistachios for decorating the finished cake.
- Mix Dry Ingredients: In a large bowl, combine the processed pistachios (except the reserved amount), almond flour, oat flour, baking powder, baking soda, and kosher salt. Whisk together to incorporate evenly.
- Mix Wet Ingredients: In a separate large bowl, add the granulated sugar and lemon zest. Using your fingers, rub the zest into the sugar for about 1 minute to release the lemon oils and flavor. Then add the eggs, Greek yogurt, lemon juice, and almond extract. Whisk these together until smooth and fully combined.
- Combine Wet and Dry Ingredients: Pour the dry ingredients into the wet ingredients bowl. Stir gently but thoroughly with a wooden spoon until a smooth batter forms. Optionally, add 1 to 2 drops of dye-free food coloring for a more vibrant green tint, and mix well.
- Bake the Cakes: Evenly distribute the batter into the prepared pans and smooth the tops with a spatula. Bake for 18-25 minutes if using 8-inch pans, or 22-28 minutes if using 6-inch pans. Cakes are done when a toothpick or tester inserted in the center comes out clean or with only a few moist crumbs attached. Allow the cakes to cool completely to room temperature before removing from pans.
- Prepare Frosting: Make the Lovely Lemon Frosting according to its recipe (not included here).
- Assemble the Cake: Place 1 to 2 tablespoons of frosting on your cake stand and spread to anchor the first cake layer. Carefully run a butter knife around the edges of the pans and invert each cake layer flat-side up onto the cake stand. Spread about ½ heaping cup of frosting over the first layer, then add 3 tablespoons of strawberry jam, spreading close to the edges but leaving a ¼ inch border. Add the next cake layer and repeat the frosting and jam layering. For three layers, repeat again and then frost the top and sides with a thin, uniform crumb coat using a bench scraper or offset spatula. Chill the cake in the fridge for 15-20 minutes until the crumb coat is firm.
- Final Frosting and Decoration: After chilling, apply a final smooth layer of frosting over the cake. It’s okay if the sides are slightly ‘naked.’ Garnish the top with a dusting of the reserved ground pistachios and fresh strawberries or mixed berries just before serving to maintain freshness.
- Storage: Serve immediately or store the decorated cake well-covered in the refrigerator for up to 5 days to maintain freshness.
Notes
- Use parchment paper in the pans to prevent sticking and ensure easy cake removal.
- Ground pistachios can be roasted or raw, but roasted will add a more pronounced flavor.
- Eggs should be at room temperature for better mixing and texture.
- This cake is gluten-free if you use gluten-free oat flour.
- The cake can be made a day ahead and stored wrapped in the refrigerator before frosting.
- For a more vibrant color, add natural, dye-free food coloring as desired.
- Be careful not to spread jam to the edges to avoid it leaking out.
