Step‑by‑Step Instructions for Pistachio and Blackberry Olive Oil Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats up, take care of your cake pans: grease them lightly with olive oil and line the bottoms with parchment paper to ensure easy release. This ensures your Pistachio and Blackberry Olive Oil Cake will bake evenly and come out smoothly.
Step 2: Prepare the Pistachios
Next, grind the shelled pistachios into a fine meal using a food processor. Be careful not to over-process them into a paste; you want to maintain some texture. Set the ground pistachios aside as they will add that luscious, nutty flavor and moisture to your cake.
Step 3: Mix Wet Ingredients
In a large mixing bowl, combine the granulated sugar, olive oil, milk, apple cider vinegar, vanilla extract, and almond extract. Use a whisk to blend these ingredients until they’re fully incorporated and the sugar has begun to dissolve. This mixture forms the rich base that enhances the overall flavor of the Pistachio and Blackberry Olive Oil Cake.
Step 4: Combine the Dry Ingredients
In a separate bowl, mix together the all-purpose flour, baking powder, salt, and the prepared pistachio meal. Stir these dry ingredients until they are well combined, ensuring there are no clumps. This will create the perfect dry mix that complements the moistness of your wet ingredients.
Step 5: Combine Mixtures
Gradually pour the dry ingredient mixture into the wet mixture, stirring gently until just combined. Avoid over-mixing, as this could lead to a dense cake. You want the batter to be smooth with a few small lumps; this signals that you are on your way to a perfectly tender Pistachio and Blackberry Olive Oil Cake.
Step 6: Bake the Cake
Pour the batter evenly into your prepared cake pans. Place them in the preheated oven and bake for about 25-30 minutes. Check for doneness by inserting a toothpick into the center of the cakes; it should come out clean or with just a few moist crumbs attached.
Step 7: Cool the Cakes
Once baked, remove the cakes from the oven and allow them to cool in the pans for about 10 minutes. After that, gently run a knife around the edges and invert the cakes onto wire racks to cool completely. This is a crucial step for ensuring the best texture before frosting.
Step 8: Make the Buttercream
To prepare the salted blackberry buttercream, beat the salted butter in a mixing bowl until creamy. Gradually add the powdered sugar, blackberry preserves, and dried thyme (if using), mixing until smooth and fluffy. The flavors will come together beautifully for a decadent frosting experience in your Pistachio and Blackberry Olive Oil Cake.
Step 9: Assemble the Cake
Once the cakes are completely cool, place one layer on a serving plate. Spread a generous amount of the blackberry thyme buttercream on top, and then stack the second layer on top. Frost the top and sides of the cake with the remaining buttercream, creating a beautiful finished look that’s sure to impress.
Step 10: Garnish and Serve
For the final touch, garnish your Pistachio and Blackberry Olive Oil Cake with fresh blackberries and a sprinkle of thyme just before serving. These toppings not only add visual appeal but also enhance the flavors with a burst of freshness. Your cake is now ready to be enjoyed!

Pistachio and Blackberry Olive Oil Cake Recipe FAQs
What should I look for when selecting pistachios?
Choose shelled pistachios that are vibrant in color and free from dark spots or signs of moisture. Unsalted pistachios are recommended as they provide better control over the cake’s overall saltiness, allowing the dessert’s natural flavors to shine.
How should I store the Pistachio and Blackberry Olive Oil Cake?
Store your cake in an airtight container in the refrigerator for up to 4-5 days. To keep it fresh, avoid exposing it to air, as this can dry it out. If you frosted the cake, you might want to place a piece of wax paper between the frosting and the lid of the container to maintain its decorative finish.

What if my cake doesn’t rise properly?
If your cake doesn’t rise, it could be due to expired baking powder or over-mixing the batter. To ensure proper leavening, check the baking powder’s expiration date and gently combine wet and dry ingredients until just mixed; a few lumps are perfectly fine.
Is this cake suitable for people with nut allergies?
Unfortunately, this Pistachio and Blackberry Olive Oil Cake is not suitable for individuals with nut allergies. However, if you’re looking for a nut-free alternative, you may try substituting the pistachios with sunflower seeds or an additional flour blend; keep in mind that taste and texture will differ.
Can I make this cake gluten-free?
