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 that’s warming up, take two 6- or 7-inch round cake pans and grease them generously with olive oil or butter. Dust the pans lightly with flour, ensuring the edges are coated to help your Pistachio and Blackberry Olive Oil Cake release easily once baked.
Step 2: Create Buttermilk Substitute
In a medium bowl, combine 1 cup of milk (or your preferred plant-based milk) with 1 tablespoon of apple cider vinegar or lemon juice. Allow this mixture to sit for about 5 minutes to thicken, creating a homemade buttermilk. This step adds moisture and a subtle tang to your cake, which is essential for flavor.
Step 3: Blend Pistachios and Sugar
Using a food processor, pulse together the ground pistachios and sugar until finely blended, creating a consistent mixture. This should take about 30 seconds. This nutty blend will serve as the base for your cake’s unique flavor and texture, enhancing the overall richness of the Pistachio and Blackberry Olive Oil Cake.
Step 4: Combine Dry Ingredients
In a large mixing bowl, whisk together the pistachio-sugar mixture with 1 ½ cups of all-purpose flour, 2 teaspoons of baking powder, and a pinch of salt. Mix until evenly combined. This dry mixture forms the fundamental body of your cake, so ensure there are no lumps for a smooth, tender crumb.
Step 5: Mix Wet Ingredients
In a separate bowl, whisk the buttermilk mixture, ½ cup of olive oil, and 1 teaspoon each of vanilla and almond extracts until fully combined. Use a whisk or fork for about 1 minute until the mixture appears smooth and blended. This luscious liquid will infuse moisture and flavor into your Pistachio and Blackberry Olive Oil Cake.
Step 6: Combine Wet and Dry Mixtures
Gently fold the dry ingredients into the wet mixture using a spatula. Stir until just combined, being careful not to overmix—about 20-30 strokes should suffice. The batter should remain slightly lumpy; this technique ensures your cake maintains its delightful moisture and lightness.
Step 7: Bake the Cake
Equally divide the batter between the two prepared cake pans. Tap the pans gently on the counter to release any air bubbles. Place them in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Keep an eye on them as they bake, looking for a golden-brown top.
Step 8: Cool and Chill
Once baked, remove the cake pans from the oven and let the cakes cool in the pans on a wire rack for about 10 minutes. Then, gently turn the cakes out onto the rack to cool completely. For best results and flavor, wrap and chill the cakes in the refrigerator overnight.
Step 9: Prepare the Frosting
For the frosting, beat together ½ cup of softened butter and ½ cup of blackberry preserves until smooth and creamy. Gradually add 2 cups of powdered sugar, along with a dash of salt and, if desired, a pinch of thyme. Mix until fluffy, creating a sweet and tangy frosting to complement your Pistachio and Blackberry Olive Oil Cake.
Step 10: Assemble the Cake
Once the cake layers are fully chilled, place one layer on a serving plate. Spread a layer of frosting, then add a generous tablespoon of blackberry preserves. Top with the second cake layer, spreading frosting on the top and sides. Garnish with fresh blackberries and chopped pistachios to create an irresistible presentation for your cake.

You can store it in the freezer for up to 2 months. When you’re ready to enjoy it, simply thaw in the refrigerator for several hours or overnight.

Are there any allergy considerations I should be aware of?
Definitely! This cake contains nuts, specifically pistachios, which can be a common allergen.
