Step‑by‑Step Instructions for Pistachio and Blackberry Olive Oil Cake Recipe
Step 1: Preheat and Prepare Pans
Preheat your oven to 350°F (175°C). While it warms up, grease two 6- or 7-inch cake pans with butter and dust them with flour. For a seamless release, line the bottoms of the pans with parchment paper, ensuring an easy transition when it’s time to remove your Pistachio and Blackberry Olive Oil Cake.
Step 2: Make Buttermilk Substitute
In a small bowl, combine milk with a splash of apple cider vinegar or lemon juice to create a homemade buttermilk substitute. Allow this mixture to sit for about 5 minutes until it thickens slightly. This step is crucial for achieving the tender, moist texture in your cake.
Step 3: Blend Pistachios and Sugar
In a food processor, pulse the finely ground pistachios together with the sugar until well combined, making sure to retain a bit of texture. This mixture will add an incredible nutty flavor to your Pistachio and Blackberry Olive Oil Cake, so take care to blend thoroughly but avoid it becoming too fine.
Step 4: Combine Dry Ingredients
In a medium mixing bowl, whisk together the ground pistachio-sugar mixture, all-purpose flour, baking powder, and salt. Combine thoroughly until the dry ingredients are evenly mixed. The baking powder is essential for the cake’s rise, giving your treat a light and fluffy crumb.
Step 5: Mix Wet Ingredients
In a separate large bowl, whisk together the homemade buttermilk, olive oil, vanilla extract, and almond extract until fully blended. The olive oil will add moisture and enhance the flavor of your Pistachio and Blackberry Olive Oil Cake, contributing to its signature richness and delightful crumb.
Step 6: Fold Dry and Wet Ingredients
Gently fold the dry mixture into the wet ingredients until just combined. It’s important to mix lightly to avoid overworking the batter, which could result in a dense cake. A few small lumps are perfectly fine; we want to maintain that lovely moist texture!
Step 7: Divide and Bake Batter
Carefully divide the batter evenly between the prepared cake pans. Place them in the preheated oven and bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean. The cakes should be lightly golden on the edges, indicating they are perfectly baked.
Step 8: Cool and Refrigerate Cakes
Once baked, allow the cakes to cool completely in the pans for about 10 minutes. Then, gently remove them from the pans and place them on a wire rack. For optimal flavor and texture, wrap the cakes in plastic wrap and refrigerate them overnight.
Step 9: Prepare the Frosting
For the buttercream frosting, beat softened room temperature butter in a medium bowl until creamy. Gradually add the blackberry preserves and powdered sugar, mixing after each addition until it’s fluffy and well combined. Finally, stir in the vanilla extract, salt, and fresh thyme until evenly incorporated.
Step 10: Assemble and Frost Cake
Once the cake layers are chilled and firm, level the top of the first layer with a knife. Spread a layer of buttercream and a layer of blackberry preserves on top, then carefully place the second layer on top. Frost the entire cake with the remaining buttercream and garnish with fresh blackberries and a sprinkle of chopped pistachios.

Expert Tips for Pistachio and Blackberry Olive Oil Cake
-
Fine Ground Pistachios: Ensure the pistachios are finely ground for even texture throughout the cake. Coarser nuts can lead to uneven distribution in your Pistachio and Blackberry Olive Oil Cake.
-
Proper Measuring: Always measure flour by spooning it into the cup and leveling off with a knife. This prevents using too much, which can result in a dry cake.
-
Avoid Overmixing: Once you combine dry and wet ingredients, fold gently until just combined. Overmixing can lead to a dense texture instead of the lightness you desire.
-
Chill Layers: Refrigerating the cake layers overnight allows flavors to meld and makes frosting easier. It reduces crumbs during frosting, giving a cleaner finish.
-
Garnish with Care: Add fresh blackberries and chopped pistachios on top just before serving for a vibrant, fresh touch. This keeps them from becoming soggy and ensures a lovely presentation.
