Step‑by‑Step Instructions for Pistachio and Blackberry Olive Oil Cake Recipe
Step 1: Preheat and Prepare Pans
Begin by preheating your oven to 350°F (175°C). While it warms up, prepare two 6- or 7-inch cake pans by buttering the bottoms and sides, then dusting them with flour. To prevent sticking, line the bottoms with parchment paper. This will ensure your Pistachio and Blackberry Olive Oil Cake releases easily once baked.
Step 2: Create Homemade Buttermilk
In a small bowl, mix the milk with apple cider vinegar, stirring gently to combine. Let it rest for about five minutes until it thickens slightly and resembles buttermilk. This mixture not only moistens the batter but also adds a delightful tang, enhancing the overall flavor of your cake.
Step 3: Process Pistachios and Sugar
Add the ground pistachios and sugar to a food processor, pulsing until finely ground but not overly powdery. The goal here is to achieve a sandy texture that will infuse the cake with nutty flavor. This will be a key ingredient in your Pistachio and Blackberry Olive Oil Cake, creating its signature taste.
Step 4: Combine Dry Ingredients
In a large mixing bowl, combine the ground pistachio-sugar mixture with flour, baking powder, and salt. Whisk these dry ingredients together until they are well incorporated. This step ensures that the leavening agent is evenly distributed, which is essential for the cake’s rise and texture.
Step 5: Mix Wet Ingredients
In a separate bowl, whisk together the homemade buttermilk, olive oil, vanilla extract, and almond extract. If desired, add a drop or two of green food dye for color. Mix until combined, allowing the flavors to meld beautifully. This wet mixture will blend with the dry ingredients, transforming them into a smooth batter.
Step 6: Combine Wet and Dry Mixtures
Gently fold the dry ingredients into the wet mixture, using a spatula to combine them until just incorporated. Take care not to overmix; a few lumps are perfectly fine. This gentle approach ensures your Pistachio and Blackberry Olive Oil Cake remains tender and light.
Step 7: Bake the Cakes
Evenly divide the batter between the prepared cake pans. Bake in the preheated oven for 25-30 minutes. Keep an eye on them, and check for doneness by inserting a toothpick into the center; it should come out clean. Your cakes should look golden brown and slightly domed.
Step 8: Cool and Chill
Once baked, remove the cakes from the oven and let them cool in the pans on a wire rack for about 10 minutes. After that, carefully turn them out onto the wire rack to cool completely. Wrap the cooled layers tightly and refrigerate overnight to enhance the flavors and ease frosting.
Step 9: Make the Frosting
To prepare the frosting, beat the room temperature butter in a mixing bowl until creamy. Gradually add blackberry preserves and powdered sugar, mixing well. Then, incorporate vanilla, salt, and dried thyme, whipping until light and fluffy. This vibrant frosting complements the cake beautifully.
Step 10: Assemble the Cake
Once the cake layers are completely cooled, use a serrated knife to level them if needed. Stack the layers on a serving platter, spreading frosting and a layer of blackberry preserves between each cake. Frost the outer layer with the remaining frosting, creating a smooth finish.
Step 11: Garnish and Serve
Finally, garnish your Pistachio and Blackberry Olive Oil Cake with fresh blackberries and a sprinkle of chopped pistachios. This not only adds a pop of color but also a delightful crunch. Slice, serve, and immerse yourself in the delicious textures and flavors of this elegant cake!

How to Store and Freeze Pistachio and Blackberry Olive Oil Cake
Room Temperature: The cake can be stored at room temperature, covered, for up to 2 days. However, it’s best to enjoy it fresh for the ultimate taste experience.
Fridge: To maintain moisture, wrap the cake tightly in plastic wrap or aluminum foil and store in the fridge for up to 4 days. This will help preserve its delightful flavors.
Freezer: For longer storage, freeze the cake layers individually, wrapped tightly in plastic wrap and aluminum foil, for up to 2 months. Thaw in the fridge overnight before frosting and serving.
Reheating: If serving leftovers, allow the cake to come to room temperature before enjoying. For a warm treat, microwave slices for about 10-15 seconds, but be cautious not to overheat.
Make Ahead Options

When you’re ready to serve, simply let the layers sit at room temperature for about an hour, frost the layers, and garnish with fresh blackberries and chopped pistachios for an elegant finish—just as delightful as if made fresh that day!

Pistachio and Blackberry Olive Oil Cake Recipe FAQs
How do I select the best pistachios for the cake?
Absolutely! Look for pistachios that are vibrant in color and free from dark spots. They should feel firm and slightly oily to the touch. If you’re buying shelled pistachios, make sure they are unsalted to avoid altering the cake’s flavor.
What is the best way to store leftover cake?
Very! Wrap the Pistachio and Blackberry Olive Oil Cake tightly in plastic wrap or aluminum foil and store it in the refrigerator. It can stay fresh for up to 4 days. If you’d like to enjoy it later, consider freezing portions for up to 2 months.
Can I freeze the cake layers?

What if my cake doesn’t rise properly?
If your Pistachio and Blackberry Olive Oil Cake didn’t rise well, there might be a couple of reasons. Check if your baking powder is fresh—expired baking powder can lead to a flat cake. Make sure you mixed the ingredients gently; overmixing can cause the cake to be dense. Also, ensure you’ve used the correct measurements for each ingredient.
Is this cake suitable for people with allergies?
Very! While this cake is vegetarian, it does contain nuts and dairy. For those allergic to nuts, consider substituting with seeds such as sunflower seeds.
