Pistachio and Blackberry Olive Oil Cake Ingredients
• The perfect balance of flavors awaits with these essential ingredients to create your delicious cake!
For the Cake
- All-Purpose Flour – This forms the cake’s structure; use a gluten-free blend for an alternative.
- Ground Pistachios – Adds a lovely nutty flavor and texture; other nuts can be used, but pistachios shine in this recipe!
- Granulated Sugar – Sweetens the cake and adds moisture; coconut sugar is a healthier swap.
- Baking Powder – Acts as a leavening agent for a light, fluffy cake; make sure it’s fresh!
- Salt – Enhances all the flavors; use less if your pistachios are salted.
- Milk – Provides moisture; plant-based milk combined with apple cider vinegar is perfect for a vegan option.
- Olive Oil – Ensures moisture and a fruity flavor; opt for extra virgin for the best results.
- Vanilla Extract – Elevates the cake’s flavor; feel free to use almond extract for a twist.
- Blackberry Preserves – Offers a deliciously sweet-tart filling; fresh blackberries can be used to create a vibrant compote.
For the Frosting
- Room Temperature Butter – Serves as the creamy base for the frosting; vegan butter is a great substitute for dairy-free needs.
- Powdered Sugar – Sweetens the buttercream and adds structure; adjust the amount for your desired sweetness.
- Dried Thyme – Introduces an intriguing herbal note; substitute with rosemary for a different flavor profile.
As you gather these ingredients, you’ll see how easy it is to create the sensational Pistachio and Blackberry Olive Oil Cake that will become a staple for all your gatherings!
Step‑by‑Step Instructions for Pistachio and Blackberry Olive Oil Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, take two 6- or 7-inch cake pans and generously grease them with olive oil or butter, then lightly flour the surfaces. This ensures that your Pistachio and Blackberry Olive Oil Cake will slide out easily once baked and stay perfectly intact.
Step 2: Create Buttermilk
In a small bowl, combine your chosen milk with apple cider vinegar and let it sit for about 5-10 minutes. This mixture will curdle slightly, creating a homemade buttermilk that enhances the cake’s moistness and flavor. It’s an essential step to achieve the tender crumb that you’ll love!
Step 3: Prepare the Pistachio Mixture
Next, take a food processor and add the ground pistachios along with granulated sugar. Pulse them together until they form a fine mixture, very similar in texture to powdered sugar. This step infuses your Pistachio and Blackberry Olive Oil Cake with the rich, nutty flavor that makes it so special.
Step 4: Combine Dry Ingredients
In a medium mixing bowl, whisk together the ground pistachio-sugar mixture with all-purpose flour, baking powder, and salt. Mix until well combined, ensuring there are no lumps. This creates the dry base for your cake. Having these dry ingredients ready will help when mixing with the wet ingredients in the next step.
Step 5: Mix Wet Ingredients
In a separate larger bowl, blend the buttermilk mixture, olive oil, and vanilla extract using a whisk or electric mixer until smooth and creamy. The olive oil will add moisture and depth of flavor to the cake, while the vanilla enhances the overall taste profile. This is where the magic begins!
Step 6: Combine Wet and Dry Mixtures
Gently fold the dry mixture into the wet ingredients, using a spatula to combine them just until there are no dry spots. Be careful not to overmix, as this can lead to a denser cake. We want your Pistachio and Blackberry Olive Oil Cake to remain light and airy, so a few flour streaks are okay at this stage.
Step 7: Bake the Cake
Divide the batter equally between your prepared cake pans and smooth the tops. Place them in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The cakes should be golden brown and springy to the touch—this indicates they are perfectly baked!
Step 8: Cool and Chill
Once baked, remove the cakes from the oven and let them cool in the pans for about 10 minutes. Carefully turn them out onto a wire rack to cool completely. For the best texture, refrigerate the layers overnight. This will help your Pistachio and Blackberry Olive Oil Cake stay moist and flavorful.
Step 9: Make the Frosting
While the cakes cool, prepare the buttercream frosting. In a mixing bowl, beat softened room temperature butter with blackberry preserves until fluffy. Gradually add powdered sugar and dried thyme, mixing until smooth and creamy. This delightful frosting will complement the layers of your cake perfectly.
Step 10: Assemble the Cake
Take the cooled cake layers and place one layer on a serving platter. Evenly spread a generous amount of frosting on top, then stack the second layer. Continue frosting the top and sides until beautifully coated. Decorate with fresh blackberries and chopped pistachios for a stunning presentation of your Pistachio and Blackberry Olive Oil Cake!
