After making it, I can confidently say it’s perfect for both everyday treats and special celebrations. You can also enjoy similar flavors with a New Orleans Roast Beef Po’ Boy Recipe if you’re looking for hearty savory options.
Ingredients You Need
Here’s what you’ll need to create this beautiful and flavorful cake:

How to Make Pistachio and Blackberry Olive Oil Cake
Prepare Your Ingredients
I like to measure everything first and grind the pistachios finely. This ensures the cake has a tender crumb. I also sift the flour and baking powder to avoid lumps.
Make the Cake Batter
Mix the dry ingredients, then whisk together the wet ingredients separately. Slowly fold the dry into the wet, mixing just until combined to keep the cake light and soft.
Bake the Cake
Pour the batter evenly into greased cake pans. Bake until a toothpick comes out clean. Let the layers cool completely on a wire rack before assembling.
Prepare the Buttercream
I beat softened salted butter until fluffy, then gradually add powdered sugar, blackberry preserves, and a hint of thyme. The result is a creamy, slightly tangy frosting that pairs perfectly with pistachio cake.
Assemble the Cake
Trim the cake layers for a level surface. Spread blackberry preserves between layers, then frost with buttercream. Chill slightly if needed to make spreading easier.
Garnish and Serve
Top with fresh blackberries and optional thyme sprigs. The contrast of colors makes it look elegant and appetizing. Slice carefully with a warm knife for clean edges.
Additional Tips for Making This Recipe Better
From my experience, these tips make a big difference:
- I always use high-quality olive oil for richer flavor.
- Grinding pistachios just right keeps the cake moist, but don’t over-process.
- I mix the batter gently after adding flour to avoid a dense cake.
- Chilling the buttercream slightly helps with smoother frosting.
- I add fresh berries right before serving to keep them vibrant.
How to Serve Pistachio and Blackberry Olive Oil Cake
This cake looks gorgeous on its own, but I like to dress it up:
- Serve slices on a white or pastel plate to highlight colors.
- Garnish with extra fresh blackberries and a small thyme sprig.
- Pair with a dollop of whipped cream or a scoop of vanilla ice cream for an indulgent touch.
- Serve slightly chilled to keep the buttercream firm.

Make Ahead and Storage
Storing
I store the frosted cake in an airtight container in the fridge. It stays fresh for 4–5 days without drying out.
Freezing
I freeze unfrosted, cooled cake layers wrapped in plastic wrap and foil. They last up to 2 months and thaw overnight in the fridge.
Reheating
I let refrigerated slices come to room temperature for 15–20 minutes before serving. This brings out the flavors and softens the buttercream slightly.
