How to Make Pistachio and Blackberry Olive Oil Cake
-
Prepare Cake Batter: Preheat your oven to 350°F (175°C) and grease your cake pans with olive oil. Grind the shelled pistachios into a coarse meal, then mix them with the all-purpose flour, baking powder, and salt. In a separate bowl, whisk together the milk, olive oil, apple cider vinegar, and vanilla extract.
-
Combine Ingredients: Slowly blend your dry mixture with the wet ingredients until just combined, being careful not to overmix. This step is crucial for achieving a tender crumb. Your batter should be somewhat thick but well-combined.
-
Bake: Divide the batter evenly between the prepared pans and bake for 25-30 minutes, or until golden brown and a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for about 10 minutes before transferring them to a wire rack to cool completely.
-
Make Buttercream: In a mixing bowl, beat the salted butter until creamy. Gradually add the powdered sugar, blackberry preserves, and dried thyme, mixing until the buttercream is smooth and fluffy. Taste and adjust sweetness if needed!
-
Assemble Cake: Once the cake layers are completely cool, level them if necessary. Spread a generous layer of blackberry preserves between the two cake layers, then frost the top and sides with the buttercream, creating an even and beautiful finish.
-
Garnish: Just before serving, decorate the top of your cake with fresh blackberries and a few sprigs of thyme for that extra touch of elegance and flavor.
Optional: For a festive flair, consider adding a sprinkle of crushed pistachios on top!

Helpful Tricks for Pistachio and Blackberry Olive Oil Cake
-
Quality Ingredients Matter: Use high-quality olive oil for enhanced flavor, as well as fresh, ripe blackberries to make every bite exceptional.
-
Avoid Overmixing: Mix your batter until just combined. Overmixing can lead to a dense cake instead of the light, moist texture desired in a Pistachio and Blackberry Olive Oil Cake.
-
Chill Before Assembling: After baking, allow your cake layers to cool completely and chill them in the fridge. This makes leveling and frosting easier, ensuring a smooth finish.
-
Properly Grind Pistachios: Grind pistachios to a fine meal, but be careful not to turn them into butter. This texture adds the delightful crunch your cake needs.
-
Level Cake Layers: Use a serrated knife to trim the tops of your cake layers, ensuring they are even. This makes for a beautifully stacked and stable cake.
How to Store and Freeze Pistachio and Blackberry Olive Oil Cake
Fridge: Store the cake in an airtight container for up to 4–5 days. Keep it well-wrapped to prevent it from drying out or absorbing strong odors from the refrigerator.
Freezer: For longer storage, slice the Pistachio and Blackberry Olive Oil Cake and wrap each piece in plastic wrap, then place them in a freezer-safe bag. It can be frozen for up to 2 months.
Thawing: To enjoy, simply take out the desired slices and allow them to thaw in the refrigerator overnight, or let them sit at room temperature for about an hour.
Reheating: If you prefer a warm slice, reheat in the microwave for about 15-20 seconds or gently warm in an oven at low heat before serving.

Can I freeze the cake? How do I do it?
Yes, you can absolutely freeze this delightful cake! After it cools completely, slice the cake and individually wrap each piece in plastic wrap. Place them in a freezer-safe bag, and it will keep well for up to 2 months. To thaw, simply move slices to the refrigerator overnight or let them sit at room temperature for about an hour before serving.
What if my cake comes out too dense?
That can happen sometimes, but no worries! If your cake is dense, it’s likely due to overmixing the batter. To keep it light and airy, mix the dry and wet ingredients until just combined. Remember, a few lumps are fine! Also, make sure your leavening agents, like baking powder, are fresh.
Are there any allergies to consider with this recipe?
Great question! This cake is nut-based due to the pistachios, so it’s not suitable for individuals with nut allergies. Additionally, if you’re accommodating dietary restrictions, you can substitute regular milk with almond milk, and use gluten-free flour for a gluten-free option.
What can I substitute if I can’t find blackberry preserves?
The more the merrier! If blackberry preserves aren’t available, you can use seedless raspberry or blueberry preserves as delightful alternatives. Both will add that sweet and tangy flavor that complements the cake perfectly!
