Step‑by‑Step Instructions
- Preheat your oven to 350°F (175°C) and grease and flour two 6- or 7-inch round cake pans.
- Make homemade buttermilk by combining 1 cup of milk with 1 tablespoon of apple cider vinegar or lemon juice and let sit for 5 minutes.
- Blend the ground pistachios with granulated sugar until fine in a food processor.
- In a medium mixing bowl, whisk together the pistachio-sugar mixture, all-purpose flour, baking powder, and salt.
- In a large mixing bowl, combine the buttermilk, olive oil, vanilla extract, and optional almond extract.
- Carefully fold your dry ingredients into the wet mixture until just combined.
- Pour the batter evenly into prepared pans and bake for 25-30 minutes.
- Allow cakes to cool in the pans for about 10 minutes, then turn them out onto a wire rack.
- Beat softened butter until creamy, then mix in blackberry preserves and gradually add powdered sugar and thyme.
- Once cool, assemble the cake by layering with buttercream and blackberry preserves, and decorate as desired.

Notes
For best results, chill the cake layers overnight before frosting. Use high-quality olive oil for superior flavor.
