Pistachio and Blackberry Olive Oil Cake Ingredients
For the Cake
• Ground pistachios – Adds nutty flavor and texture; feel free to substitute with finely ground almonds for a different nutty profile.
• Sugar – Provides sweetness and structure; you can use a sweetener of your choice but expect slight texture changes.
• All-purpose flour – Forms the cake’s structure; gluten-free flour works if you’re looking for a gluten-free option.
• Baking powder – Acts as a leavening agent, helping the cake rise beautifully.
• Salt – Enhances all flavors in the cake for a well-rounded taste.
• Olive oil – Keeps the cake moist and adds a fruity note; for the best flavor, opt for extra virgin olive oil.
• Homemade buttermilk (milk + vinegar/lemon juice) – Adds moisture and a tender crumb; use plant-based milk mixed with vinegar for a dairy-free option if desired.
• Vanilla extract – Provides aromatic flavor that complements the other ingredients; almond extract can be substituted for a different profile.
• Almond extract – Enhances nuttiness (optional but delightful).
• Blackberry preserves – Adds sweetness and fruitiness throughout the cake; feel free to swap with raspberry or strawberry preserves if preferred.
For the Frosting
• Butter – Creates a creamy texture in the frosting; replace with plant-based butter for a vegan option.
• Powdered sugar – Sweetens and thickens the frosting for the perfect balance.
• Dried thyme – Introduces a subtle herbaceous note; you can omit or replace it with rosemary for a different flavor experience.

Step‑by‑Step Instructions for Pistachio and Blackberry Olive Oil Cake
Step 1: Preheat the Oven and Prepare Pans
Begin by preheating your oven to 350°F (175°C). While the oven warms up, take two 6- or 7-inch cake pans, grease them well with olive oil or butter, and lightly dust them with flour to ensure the Pistachio and Blackberry Olive Oil Cake releases effortlessly after baking.
Step 2: Make the Buttermilk Substitute
In a small bowl, combine a cup of milk with a tablespoon of apple cider vinegar or lemon juice. Let this mixture sit for about 5 minutes to curdle slightly, creating a buttermilk substitute that not only adds moisture but also enhances the cake’s tender crumb.
Step 3: Prepare the Pistachios and Dry Ingredients
Place the ground pistachios and sugar into a food processor, blending them until finely ground. In a separate large mixing bowl, whisk together the ground pistachios, all-purpose flour, baking powder, and a pinch of salt until they are thoroughly combined, setting the stage for a flavorful cake.
Step 4: Combine Wet Ingredients
In another bowl, whisk together the prepared buttermilk, olive oil, and vanilla extract. If you’re feeling adventurous, add a few drops of food dye for a vibrant color. This mixture will blend beautifully with your dry ingredients in the next step, contributing to the moist texture of your Pistachio and Blackberry Olive Oil Cake.
Step 5: Mix Wet and Dry Ingredients
Gradually fold the dry ingredients into the wet mixture, being careful to mix until just combined. This gentle folding is crucial to avoid overmixing, which could lead to a dense cake. Look for a thick batter without visible flour streaks, ensuring a light and airy texture in your final cake.
Step 6: Bake the Cake
Evenly distribute the batter between your two prepared pans, smoothing the tops with a spatula. Place them in the preheated oven and bake for 25 to 30 minutes. You’ll know the cakes are done when a toothpick inserted in the center comes out clean, indicating a perfect bake for your Pistachio and Blackberry Olive Oil Cake.
Step 7: Cool the Cakes
Once baked, remove the cakes from the oven and let them cool in the pans for about 10 minutes. After this, gently run a knife around the edges and carefully transfer the cakes to a wire rack. For the best flavor and texture, refrigerate the cooled cakes overnight before frosting.
Step 8: Prepare the Frosting
In a mixing bowl, beat together the softened butter and blackberry preserves using an electric mixer until creamy. Gradually add in powdered sugar and a pinch of dried thyme (if using), mixing until fluffy and light. This luscious frosting will complement the flavors of your Pistachio and Blackberry Olive Oil Cake beautifully.
Step 9: Assemble the Cake
Once chilled, level the tops of your cake layers to create even surfaces. Place one layer on a serving plate and spread a layer of frosting followed by a spoonful of blackberry preserves. Stack the second layer on top, then frost the entire cake, creating smooth edges that will showcase the cake’s stunning layers.
Step 10: Decorate and Serve
To finish, beautifully decorate the top of your Pistachio and Blackberry Olive Oil Cake with fresh blackberries and a generous sprinkle of chopped pistachios for an eye-catching presentation. This delightful cake is now ready to be served, bringing joy and flavor to your gathering.

Pistachio and Blackberry Olive Oil Cake Recipe FAQs
What is the best way to select ripe blackberries for this cake?
Absolutely! When choosing blackberries, look for firm and plump berries that are deep purple to black in color. Avoid any with red or green spots, as they may be under-ripe or sour. Also, steer clear of any moldy or mushy berries, as these could affect the flavor of your delightful Pistachio and Blackberry Olive Oil Cake.
How should I store leftovers of the Pistachio and Blackberry Olive Oil Cake?
I recommend keeping the cake in an airtight container at room temperature for up to 2 days if you plan to enjoy it soon. For longer storage, place it in the refrigerator for up to 4 days to maintain its freshness and flavors. This makes it easy to grab a slice whenever the craving hits!
Can I freeze the Pistachio and Blackberry Olive Oil Cake? How?
Yes, and I often do! To freeze the cake, wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. It will keep well for up to 2 months in the freezer. When you’re ready to serve, simply thaw it overnight in the fridge for the best texture before enjoying this delicious treat.
What should I do if my batter is too thick when making the cake?
Very good question! If you find your batter too thick, it might be due to the type of flour used or not enough liquid. You can gradually add an extra tablespoon of buttermilk until you reach a more pourable consistency; just be careful not to overmix. Remember, a gentle hand here is key for that light, fluffy final cake.
Is this cake safe for people with nut allergies?
Not entirely, as the Pistachio and Blackberry Olive Oil Cake contains ground pistachios. If you’re looking to make this cake suitable for guests with nut allergies, you can replace the pistachios with seeds like sunflower seeds or pumpkin seeds, processed to a fine meal. However, be mindful that this will slightly alter the flavor of the cake. Always double-check with your guests about any allergies before serving!
How long does the frosting last? Can I make it ahead of time?
Yes, you can make the frosting ahead of time! Store it in an airtight container in the refrigerator for up to a week. Before using, let it soften at room temperature and give it a quick whip to reintroduce some lightness. This way, you can save time when preparing for those special occasions!
