Step‑by‑Step Instructions for Pistachio and Blackberry Olive Oil Cake
Step 1: Preheat Oven and Prepare Pans
Start by preheating your oven to 350°F (175°C). While it’s warming up, take two 6-inch or 7-inch cake pans and generously grease them with olive oil or butter. Dust the pans with flour, tapping out the excess, to ensure your Pistachio and Blackberry Olive Oil Cake releases effortlessly after baking.
Step 2: Make the Buttermilk
In a small bowl, combine your choice of milk (dairy or plant-based) with apple cider vinegar or lemon juice. Stir well and let it sit for about 5 minutes until it thickens slightly, resembling buttermilk. This step is crucial for adding moisture to the cake and enhancing the overall flavor.
Step 3: Process Pistachios and Sugar
Using a food processor, add the ground pistachios and sugar. Pulse until you achieve a fine consistency but avoid making it too powdery—you want some texture. This mixture will not only provide the nutty flavor but also an appealing crunch in your Pistachio and Blackberry Olive Oil Cake.
Step 4: Combine Dry Ingredients
In a mixing bowl, whisk together the pistachio-sugar mixture along with flour, baking powder, and salt. Ensure these dry ingredients are evenly combined, which will help the batter rise evenly when it’s baked, resulting in a light and fluffy cake.
Step 5: Whisk the Wet Ingredients
In a large bowl, combine the prepared buttermilk, olive oil, vanilla extract, and almond extract. Whisk these ingredients together until well blended. This mixture will add moisture and a lovely flavor to your Pistachio and Blackberry Olive Oil Cake, creating a smooth batter.
Step 6: Combine Wet and Dry Ingredients
Pour the dry ingredient mixture into the wet ingredients and gently fold them together using a spatula or wooden spoon. Mix until just combined; it’s important to avoid overmixing, as this can make your cake tough. You want a beautifully moist and tender crumb.
Step 7: Divide and Pour Batter
Carefully divide the batter evenly between the prepared cake pans, aiming for approximately 425 grams in each pan. Smooth the tops with a spatula for even baking. As you do this, enjoy the vibrant green of the pistachios mixed with the batter’s creamy texture.
Step 8: Bake the Cakes
Place the pans in the preheated oven and bake for 25–30 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean or with just a few crumbs attached. This is the perfect time to embrace the delightful aroma wafting through your kitchen!
Step 9: Cool the Layers
Once baked, remove the cake pans from the oven and let them cool for about 10 minutes. Carefully turn them out onto wire racks to cool completely. For enhanced flavor, wrap the layers in plastic wrap and refrigerate overnight, allowing the flavors to meld beautifully.
Step 10: Prepare the Frosting
In a mixing bowl, beat the room temperature butter until creamy. Gradually add blackberry preserves, mixing until combined, and then slowly incorporate powdered sugar to achieve a smooth, pliable frosting. This luscious frosting is perfect for complementing the fruity notes of your Pistachio and Blackberry Olive Oil Cake.
Step 11: Assemble the Cake
Level the top of one cake layer if necessary, then spread a layer of frosting on top along with a layer of blackberry preserves. Gently place the second cake layer on top and frost the entire cake with the remaining frosting. Enjoy the bright colors as they come together for a beautiful presentation.
Step 12: Garnish and Serve
Finally, garnish your Pistachio and Blackberry Olive Oil Cake with fresh blackberries and a sprinkle of chopped pistachios for an elegant finish. This flourish adds color and extra flavor, making your cake not just delicious but a stunning centerpiece for any occasion.

Pistachio and Blackberry Olive Oil Cake Recipe FAQs
What kind of pistachios should I use for the cake?
Absolutely! Look for raw or roasted unsalted pistachios for the best flavor and texture. Make sure they’re fresh, as old or stale nuts can affect the overall taste. You can also substitute with almonds for a different flavor profile, but the cake will have a distinctively different taste.
How should I store leftover cake?
To keep your Pistachio and Blackberry Olive Oil Cake fresh, wrap it tightly in plastic wrap or place it in an airtight container. It will stay fresh for up to 4 days at room temperature. If you plan to keep it longer, storing it in the fridge is ideal.
Can I freeze the cake? How?

What should I do if my cake sinks in the middle?
If your cake sinks in the middle, it could be due to underbaking or overmixing the batter. Ensure you bake your cake until a toothpick comes out clean and fold the batter gently to avoid excess air. If it does sink, try slicing the top off and turning it into a delightful trifle!
Is this cake suitable for those with nut allergies?
Unfortunately, this Pistachio and Blackberry Olive Oil Cake contains nuts, so it’s not suitable if you’re allergic to them. However, you can enjoy similar flavor profiles by using nut-free alternatives, such as sunflower seeds or pumpkin seeds, although the overall texture and taste will differ.
Can I use a different fruit instead of blackberries?
Very! Feel free to experiment with fruits like raspberries, cherries, or even peaches. Just keep in mind that the sweetness and tartness will change depending on the fruit you choose, so adjust the sugar in the recipe if necessary to keep your cake balanced.
