Step‑by‑Step Instructions for Pistachio and Blackberry Olive Oil Cake
Step 1: Preheat and Prepare Pans
Begin by preheating your oven to 350°F (175°C). While the oven heats up, grease and flour two 6- or 7-inch round cake pans to ensure the Pistachio and Blackberry Olive Oil Cake releases easily once baked. Take a moment to gather all your ingredients, setting the stage for a delightful baking experience.
Step 2: Create Buttermilk
In a small bowl, combine your choice of milk with apple cider vinegar or lemon juice. Allow it to sit for about 5 minutes to curdle, creating a homemade buttermilk that adds moisture to the cake. This step is crucial for achieving a tender crumb and enhances the overall flavor of your cake.
Step 3: Blend Pistachio Mixture
In a food processor, blend the ground pistachios with granulated sugar until they reach a fine texture, almost like a sandy consistency. This nutty mixture will be the heart of your Pistachio and Blackberry Olive Oil Cake, infusing it with rich, aromatic flavors that complement the fresh blackberries beautifully.
Step 4: Combine Dry Ingredients
In a large mixing bowl, whisk together all-purpose flour, baking powder, salt, and the pistachio-sugar mixture until evenly combined. This is an essential step to ensure every bite of the cake boasts a harmonious blend of flavors. Take note of the inviting nutty scent as you mix!
Step 5: Mix Wet Ingredients
In a separate bowl, combine the prepared buttermilk, olive oil, vanilla extract, and almond extract. Whisk them together until combined. The olive oil adds luxurious moisture, making your Pistachio and Blackberry Olive Oil Cake delightfully tender while the extracts provide an aromatic boost that elevates its taste.
Step 6: Combine Mixtures
Gently fold the dry ingredients into the wet mixture until just combined. Be careful not to overmix; you want the batter to remain light and airy. It’s perfectly fine if there are a few lumps—this will contribute to the tender texture of your cake.
Step 7: Bake the Cake
Divide the batter evenly between the two prepared cake pans. Bake in your preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The cakes should be golden brown on the edges and spring back when lightly pressed.
Step 8: Cool the Cakes
Once baked, remove the cake pans from the oven and let them cool for about 10 minutes. Carefully transfer the cakes to a wire rack to cool completely. For enhanced flavor and ease of assembly, consider refrigerating the layers overnight—this step is key to achieving the perfect texture!
Step 9: Prepare the Frosting
In a mixing bowl, beat softened butter until smooth and creamy. Gradually add in the blackberry preserves and powdered sugar, mixing until the frosting is fluffy and well combined. Taste and adjust sweetness if necessary; this will be the luscious topping for your Pistachio and Blackberry Olive Oil Cake.
Step 10: Assemble the Cake
Once the cakes are completely cooled, use a serrated knife to level the tops if necessary. Place the first layer on a serving plate, spread a layer of frosting and a dollop of blackberry preserves, then gently place the second cake layer on top. Use the remaining frosting to cover the top and sides.
Step 11: Garnish and Serve
To finish your gorgeous Pistachio and Blackberry Olive Oil Cake, decorate the top with fresh blackberries and a sprinkling of chopped pistachios. This not only adds a spectacular visual but also enhances the nutty flavor. Now, cut a slice and prepare for delighted reactions as you share this stunning dessert!

Pistachio and Blackberry Olive Oil Cake Recipe FAQs
What kind of pistachios should I use for this cake?
I recommend using shelled, unsalted pistachios for the best flavor and texture in your Pistachio and Blackberry Olive Oil Cake. You can find them at most grocery stores or specialty nut shops. Make sure the pistachios are fresh, as stale nuts can affect the overall taste of your cake.
How should I store leftovers from the cake?
To store leftover cake, wrap individual slices tightly in plastic wrap or place them in an airtight container at room temperature for up to 4 days. If you notice any dryness, a slight dusting of powdered sugar can help revitalize the slices before serving. For longer storage, consider refrigerating it, which will keep it fresh for up to a week.
Can I freeze the Pistachio and Blackberry Olive Oil Cake?
Absolutely! To freeze your cake, wrap the cooled layers tightly in plastic wrap, followed by aluminum foil to prevent freezer burn. This method allows the cake to maintain its moisture. You can freeze it for up to 2 months. When ready to enjoy, thaw the cake in the refrigerator overnight before serving.
What should I do if my cake doesn’t rise properly?
If your cake doesn’t rise, it could be due to expired baking powder. Always ensure your baking powder is fresh, as it’s crucial for creating a light texture. Additionally, avoid overmixing when combining wet and dry ingredients, as this can lead to a denser cake. If you see dark spots on your cake after baking, it may need more time, or the oven temperature might be too high. Keep a close eye and don’t hesitate to check.
Is this Pistachio and Blackberry Olive Oil Cake suitable for those with nut allergies?
Since this cake features ground pistachios, it is not suitable for individuals with nut allergies. However, you can create a nut-free version by substituting almond meal with a combination of sunflower seed flour and a touch of vanilla extract for flavor. Always check with guests for allergies before serving, as safety is paramount!
Can I use a different type of fruit preserve in the frosting?
Yes, you can absolutely substitute blackberry preserves with other berry preserves such as raspberry or blueberry. Each fruit will provide a unique flavor profile while still complementing the nutty pistachio base. Feel free to experiment and discover your family’s favorite version of this delightful cake!
