Step‑by‑Step Instructions for Pistachio and Blackberry Olive Oil Cake
Step 1: Preheat the Oven and Prepare Pans
Preheat your oven to 350°F (175°C). While it’s heating, generously grease and flour two 6- or 7-inch cake pans to prevent sticking. You can use parchment paper at the bottom for extra assurance and easy release. This will ensure that your Pistachio and Blackberry Olive Oil Cake comes out perfectly shaped and ready to frost.
Step 2: Make the Buttermilk
To prepare your buttermilk, combine one cup of milk (dairy or plant-based) with one tablespoon of apple cider vinegar or lemon juice in a measuring cup. Let it sit for about 5 minutes until it thickens slightly and curdles. This step not only adds moisture to your cake but also contributes to a tender crumb, enhancing the overall texture of your Pistachio and Blackberry Olive Oil Cake.
Step 3: Combine Dry Ingredients
In a food processor, pulse together 1 cup of ground pistachios and 1 cup of granulated sugar until finely ground, ensuring there’s still some texture for crunch. In a large mixing bowl, whisk this pistachio-sugar mixture with 1 cup of all-purpose flour, 1 teaspoon of baking powder, and ½ teaspoon of salt. Setting these dry ingredients aside allows their flavors to meld while you prepare the wet mixture for your cake.
Step 4: Prepare the Wet Ingredients
In a separate bowl, whisk together the prepared buttermilk, ⅓ cup of olive oil, 1 teaspoon of vanilla extract, and ½ teaspoon of almond extract until well combined. The olive oil not only adds moisture but also lends a subtle fruitiness to your cake. This mixture will add depth to your Pistachio and Blackberry Olive Oil Cake, making it delectably unique.
Step 5: Combine Wet and Dry Ingredients
Gently fold the dry ingredients into the wet mixture using a spatula. Mix until just combined, being careful not to overmix, as this can lead to a dense texture. You want to maintain the lightness of your Pistachio and Blackberry Olive Oil Cake, so stop mixing when you see a few flour streaks, allowing it to rise beautifully while baking.
Step 6: Bake the Cake
Divide the batter evenly between the prepared cake pans, smoothing the tops with a spatula. Bake in the preheated oven for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean. Your cakes should be golden brown and spring back lightly when touched. Once out of the oven, give them a few minutes to cool in the pans before transferring them to a wire rack.
Step 7: Cool the Cakes
Allow your cakes to cool completely in the pans on a wire rack for about 10 minutes, then gently turn them out and cool fully. For enhanced flavor, refrigerate the cooled cakes overnight. This cooling process will ensure a better icing surface for your layer of frosting, making your Pistachio and Blackberry Olive Oil Cake even more delightful.
Step 8: Make the Buttercream
For the buttercream, beat ½ cup of room-temperature butter with ½ cup of blackberry preserves in a mixing bowl. Gradually add 2 to 3 cups of powdered sugar, 1 teaspoon of vanilla extract, and a pinch of salt until the frosting is fluffy and spreadable. The sweetness from the blackberry preserves will beautifully complement the nuttiness of the cake, making each bite a treat.
Step 9: Assemble the Cake
To assemble your Pistachio and Blackberry Olive Oil Cake, start by frosting the top of one layer with the buttercream and a layer of blackberry preserves. Carefully place the second layer on top, then frost the top and sides of the entire cake. This creates a beautiful finish that showcases the colors and flavors awaiting inside.
Step 10: Garnish and Serve
Garnish the top of your assembled cake with fresh blackberries and finely chopped pistachios for an elegant touch. These garnishes not only add visual appeal but also enhance the flavor profile of your Pistachio and Blackberry Olive Oil Cake. Slice, serve, and enjoy the delightful combination of flavors with family and friends!

Storage Tips for Pistachio and Blackberry Olive Oil Cake
Room Temperature: Keep the cake covered at room temperature for up to 1 day. This preserves its moisture but avoid direct sunlight to maintain flavor.
Fridge: Store leftover cake in an airtight container or wrapped in plastic wrap in the fridge for up to 4 days. This will keep the Pistachio and Blackberry Olive Oil Cake fresh and delicious.
Freezer: For longer storage, slice the cake and wrap individual pieces tightly in plastic wrap. Freeze for up to 2 months; thaw overnight in the fridge before serving.
Reheating: If you prefer your cake warm, gently reheat individual slices in the microwave for about 10-15 seconds. This restores its moist texture and enhances the flavors!

With these make-ahead options, you’ll enjoy the sweet satisfaction of homemade dessert with minimal effort on busy days!

Pistachio and Blackberry Olive Oil Cake Recipe FAQs

How should I store leftover Pistachio and Blackberry Olive Oil Cake?
