How to Make Pistachio and Blackberry Olive Oil Cake

Preheat oven: Start by setting your oven to 350°F (175°C). This ensures it reaches the perfect temperature by the time your batter is ready.
Prepare the pans: Grease two 6- or 7-inch round cake pans and dust them with flour. Line the bottoms with parchment paper to prevent sticking, ensuring perfect cake removal.
Make buttermilk: Combine 1 cup of milk with 1 tablespoon of lemon juice or vinegar. Let it sit for about 5 minutes to curdle, creating a fantastic buttermilk substitute that keeps your cake moist.
Combine dry ingredients: In your food processor, blend 1 cup of ground pistachios with 1 cup of sugar until finely ground, but be careful not to powder it. This mixture adds fantastic flavor and sweetness!
Whisk together wet ingredients: In a large bowl, mix together the buttermilk, 1/2 cup of olive oil, 1 teaspoon of vanilla extract, and 1/2 teaspoon of almond extract (add green food dye if you like!) until well combined and smooth.
Mix batter: Gradually fold the pistachio-sugar mixture into the wet mixture, along with 1 1/2 cups of all-purpose flour, 2 teaspoons of baking powder, and a pinch of salt. Stir gently until only just combined, avoiding overmixing.
Bake the cake: Divide the batter between the prepared pans and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Cool and chill: Allow the cakes to cool in the pans for about 10 minutes, then carefully remove them and wrap in plastic wrap. Refrigerate overnight for the best flavor development.
Make frosting: For the frosting, beat together 1/2 cup of room temperature butter and 1/2 cup of blackberry preserves until smooth. Gradually add 2 cups of powdered sugar, 1 teaspoon of vanilla, and 1 teaspoon of dried thyme (if using) until light and fluffy.
Assemble your cake: Level the top of one layer, spread frosting on it, add a layer of blackberry preserves, then place the second cake on top. Frost the entire cake and garnish as desired.

Optional: Dust with powdered sugar or top with crushed pistachios for an extra touch!

Pistachio and Blackberry Olive Oil Cake Recipe FAQs

How should I select and store my pistachios?
When choosing pistachios, look for ones that are bright green without dark spots or mold. Always opt for unsalted, roasted pistachios for the best flavor in your cake.

What should I do if the cake layers dome or crack while baking?
