How to Make Pistachio Olive Oil Cake with Blackberry Thyme Buttercream

Preheat your oven to 350°F (175°C). Prepare two 6- or 7-inch cake pans by greasing and flouring them to ensure your cakes release easily after baking.
Create buttermilk by mixing milk with vinegar or lemon juice; let it sit for 5 minutes. This will give your cake a delightful tang and keep it moist.
Grind pistachios with sugar in a food processor until finely textured but still slightly crunchy. This adds extraordinary flavor and texture to your cake.
Whisk together the ground pistachios, flour, baking powder, and salt in a large bowl. This dry mixture forms the backbone of your cake’s fluffy structure.
Combine the buttermilk, olive oil, and vanilla in a separate bowl; add food dye if you want to enhance the cake’s color. Stir well to mix all the flavors.
Fold the dry ingredients into the wet mixture until just combined, being careful not to overmix, as this could lead to a dense cake.
Divide the batter evenly between your prepared cake pans and bake for about 25-30 minutes. Check for doneness with a toothpick—it should come out clean when the cakes are fully baked.
Cool the cakes in the pans for 10 minutes, then transfer them to a cooling rack. For the best flavor, refrigerate the cooled cakes overnight.
Beat the softened butter with blackberry preserves in a mixing bowl until smooth. Gradually add powdered sugar, vanilla, salt, and thyme, whipping until fluffy and well-blended.
Assemble the cake by leveling the layers, stacking them with frosting and blackberry preserves, and coating the top and sides with the remaining frosting. Garnish as desired for a lovely finish.

Optional: Add a sprinkle of crushed pistachios on top for extra texture and a stunning presentation.

Freezer: For longer storage, wrap each cake layer tightly in plastic wrap and foil, then freeze for up to 2 months. Thaw in the fridge overnight before enjoying.

Reheating: If you prefer your cake warm, lightly microwave individual slices for 10-15 seconds, ensuring not to overheat to maintain the cake’s moist texture.

Pistachio Olive Oil Cake with Blackberry Thyme Buttercream Recipe FAQs

How do I choose ripe ingredients for this cake?
Absolutely! When selecting your pistachios, look for those that are bright green in color and free of any dark spots or blemishes. The fresher they are, the nuttier the flavor will be. For blackberries, choose ones that are plump and firm with a deep, rich color; avoid any that appear mushy or have an unpleasant smell.

How should I store my Pistachio Olive Oil Cake with Blackberry Thyme Buttercream?
To keep your cake fresh, store it in an airtight container. At room temperature, it’s best enjoyed within 2 days, maintaining its delightful moisture. If stored in the fridge, it can last up to 4 days. For longer storage, place it in the freezer wrapped tightly in plastic wrap and aluminum foil for up to 2 months.

Can I freeze this cake? If so, how?
Yes, you can! To freeze your Pistachio Olive Oil Cake with Blackberry Thyme Buttercream, first let the cake layers cool completely. Wrap each layer individually in plastic wrap and then in foil to protect against freezer burn. When you’re ready to enjoy, thaw the layers in the refrigerator overnight, then frost and assemble as desired. This process preserves the texture and flavor beautifully!

What should I do if my cake sinks in the middle after baking?
Very often, a sinking cake is linked to overmixing the batter or using expired baking powder, so I recommend ensuring your ingredients are fresh and combining everything just until mixed. If the cake does sink, you’ll have a deliciously moist center that can be topped with more frosting or fresh berries to disguise the slight dip!

Can I make this recipe vegan?
Absolutely! To adapt your Pistachio Olive Oil Cake with Blackberry Thyme Buttercream for a vegan lifestyle, replace the buttermilk with almond or oat milk mixed with a tablespoon of vinegar, and substitute dairy butter for a plant-based alternative. These simple swaps allow everyone to enjoy this delightful dessert without compromising on flavor.

Are there any common allergies to be aware of with this cake?
Yes, it’s important to note that this cake includes nuts (pistachios) and dairy (buttermilk and butter), which are common allergens. If preparing for guests, you can easily swap pistachios with finely chopped almonds or hazelnuts and use plant-based alternatives for the dairy ingredients to create a safe and delicious treat!
