Step‑by‑Step Instructions for Pistachio and Blackberry Olive Oil Cake
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Grease two 9-inch round cake pans and line the bottoms with parchment paper for an easy release. Set the pans aside while you gather your ingredients for the pistachio and blackberry olive oil cake batter.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together 2 cups of all-purpose flour, 2 teaspoons of baking powder, and ½ teaspoon of salt until well combined. This ensures that your leavening agent is evenly distributed, which is crucial for a light and fluffy cake. The dry ingredients create the foundation for the flavorful pistachio and blackberry olive oil cake.
Step 3: Combine Wet Ingredients
In a separate large bowl, mix 1 cup of high-quality extra virgin olive oil, 1 cup of milk, and 2 tablespoons of apple cider vinegar. Add 2 teaspoons of vanilla extract and ¼ teaspoon of almond extract if using. Whisk until well combined and slightly emulsified, creating a rich base to complement the earthy pistachios.
Step 4: Combine Mixtures
Gently add the dry mixture to the wet ingredients, stirring with a spatula until just combined. Be careful not to over-mix; a few lumps are perfectly fine. This delicate process ensures that the final pistachio and blackberry olive oil cake remains soft and tender, so mix it with care.
Step 5: Incorporate Pistachios
Fold in 1 cup of finely chopped unsalted shelled pistachios to the batter, ensuring they’re evenly distributed. This step will enhance the earthy flavor and add texture to your cake. The vibrant green of the pistachios will also create a beautiful visual contrast once baked.
Step 6: Bake the Cakes
Divide the batter evenly between the two prepared cake pans, smoothing the tops with a spatula. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Keep an eye on them to avoid overbaking, as the cakes should be lightly golden and spring back when touched.
Step 7: Cool the Cakes
Once baked, remove the pans from the oven and allow the cakes to cool in the pans for 10 minutes. Then, carefully turn them out onto a wire rack to cool completely. This cooling phase is crucial before you froth your delicious blackberry buttercream onto the pistachio and blackberry olive oil cake.
Step 8: Prepare the Buttercream
In a mixing bowl, beat 1 cup of softened salted butter until creamy. Gradually add in 3-4 cups of powdered sugar, mixing until smooth. Then, incorporate ½ cup of blackberry preserves and 1 teaspoon of dried thyme, if desired, for a unique flavor twist. Beat until fully combined and fluffy, adjusting sweetness to your liking.
Step 9: Assemble the Cake
Once the cake layers are completely cool, place one layer on a serving plate. Spread a generous layer of blackberry preserves on top, followed by a layer of buttercream. Carefully add the second cake layer on top, positioning it gently to avoid breaking. This assembly creates a beautiful centerpiece, showcasing the flavors of pistachio and blackberries.
Step 10: Frost the Entire Cake
Frost the top and sides of the cake with the remaining buttercream using a spatula for a smooth finish. Don’t worry about perfection; the cozy, homemade feel is what makes this pistachio and blackberry olive oil cake irresistible. Refrigerate for about 30 minutes to set the frosting.
Step 11: Garnish and Serve
Before serving, adorn the top with fresh blackberries and a sprinkle of thyme for a final touch of color and flavor. This beautiful garnish not only enhances the presentation but brings a fresh taste that perfectly complements the cake. Slice and serve your elegant pistachio and blackberry olive oil cake to friends and family!

Expert Tips for Pistachio and Blackberry Olive Oil Cake
-
Choose Quality Oil: Use a high-quality extra virgin olive oil for the best flavor; cheaper oils can compromise the taste of your pistachio and blackberry olive oil cake.
-
Don’t Overmix: Mix your batter just until combined to keep the cake soft and fluffy. Overmixing can lead to a dense texture that won’t give you that luxurious soft crumb you’re after.
-
Cool Before Frosting: Make sure your cake layers are completely cool before adding the frosting. If they’re warm, it can melt your beautiful blackberry and thyme buttercream, making it difficult to frost.
-
Use Warm Knife for Slicing: When it’s time to serve, use a warm knife to slice your cake. This helps achieve cleaner cuts and keeps the layers intact for a more appealing presentation.
-
Customize Your Flavor: Don’t hesitate to explore different fruit preserves in place of blackberry to create exciting flavor twists. Raspberry or apricot preserves might also complement the pistachios beautifully!
-
Chill for Best Texture: Allow your frosted cake to chill in the refrigerator for at least 30 minutes before serving. This enhances the structure and allows the flavors to meld wonderfully.
Storage Tips for Pistachio and Blackberry Olive Oil Cake
Room Temperature: Store uncovered for up to 1 day at room temperature, as the cake is best enjoyed fresh. Afterward, keep it in an airtight container.
Fridge: Refrigerate in an airtight container for up to 4–5 days. This helps maintain the cake’s moisture and flavor while also keeping the frosting fresh.
Freezer: Unfrosted cake layers can be frozen for up to 2 months. Wrap them tightly in plastic wrap and then foil to prevent freezer burn.
Reheating: If desired, thaw frozen layers overnight in the fridge before assembling, or warm individual slices gently in the microwave for a few seconds to bring back moisture.
Make Ahead Options
This Pistachio and Blackberry Olive Oil Cake is a fantastic choice for meal prep, allowing you to enjoy its luxurious flavors without the last-minute rush! You can prepare the cake layers up to 3 days in advance; simply bake them, cool completely, and store in an airtight container at room temperature. For the frosting, make it up to 24 hours ahead and refrigerate in a sealed container. To maintain quality, ensure the cake layers are well-wrapped to prevent drying out.

Pistachio and Blackberry Olive Oil Cake Recipe FAQs
How do I know when my pistachios are fresh?
Absolutely! When selecting pistachios, look for ones that are plump and firm. Avoid any that have dark spots all over or a musty smell, as these could indicate spoilage. Ideally, source them from a trusted store or get them in sealed packaging to ensure quality.
What’s the best way to store the cake after baking?
Very! To keep your Pistachio and Blackberry Olive Oil Cake fresh, refrigerate it in an airtight container for up to 4-5 days. This maintains its wonderful moisture and flavor. If left at room temperature, I recommend consuming it within a day to enjoy its fresh taste.
Can I freeze the cake layers?
Certainly! If you’d like to save some for later, unfrosted cake layers can be frozen for up to 2 months. To do this, wrap each layer tightly in plastic wrap followed by aluminum foil to protect against freezer burn. When you’re ready to use them, simply thaw in the fridge overnight before frosting.
What should I do if my cake doesn’t rise?
Oh no! If your Pistachio and Blackberry Olive Oil Cake doesn’t rise properly, it’s often due to expired baking powder or overmixing the batter. Ensure you’re using fresh baking powder (check the expiration date) and gently incorporate wet and dry ingredients until just combined—lumps are okay!
Are there any allergy considerations with this cake?
Absolutely! This recipe contains nuts from the pistachios and dairy in the butter and milk. If you’re serving anyone with nut allergies, consider substituting with sunflower seeds for a different texture. You can also opt for dairy-free milk and vegan butter to cater to lactose intolerant guests.
Can I make this cake gluten-free?
Very much so! To create a gluten-free version of the Pistachio and Blackberry Olive Oil Cake, simply replace the all-purpose flour with a quality gluten-free flour blend. Make sure it’s formulated for baking so you achieve the right texture, similar to traditional cake!
