How to Make Pistachio and Blackberry Olive Oil Cake

Step 1: Preheat the Oven

Preheat the oven to 350F. Grease two cake pans with butter and dust them with flour. Line the bottom with parchment paper rounds to prevent sticking.

Step 2: Make Buttermilk Substitute

In a medium measuring cup or bowl, whisk together the oat milk and apple cider vinegar. Allow it to rest for about five minutes; this will act as your homemade buttermilk.

Step 3: Prepare Pistachio Mixture

Add the shelled pistachios and granulated sugar to a food processor. Blend until finely ground to incorporate into your cake batter smoothly.

Step 4: Combine Dry Ingredients

In a medium bowl, whisk together the pistachio-sugar mixture, all-purpose flour, baking powder, and salt. Set aside for later use.

Step 5: Mix Wet Ingredients

In a separate large bowl, whisk together the oat milk mixture, olive oil, vanilla extract, and almond extract until well combined. Optionally add green food dye if you desire an enhanced color.

Step 6: Combine Wet and Dry Mixtures

Gently fold the dry ingredient mixture into the wet mixture using a spatula or wooden spoon until just combined; avoid over-mixing.

Step 7: Fill Cake Pans

Divide the batter evenly between the two prepared cake pans. Aim for about 425 grams of batter in each pan to ensure even layers.

Step 8: Bake

Bake in your preheated oven at 350F for about 25–30 minutes. A toothpick inserted into the center should come out clean when done.

Step 9: Cool Down

Remove cakes from the oven and let them cool completely in their pans on a wire rack. For best results, wrap them in plastic wrap and chill in the fridge overnight before assembling.

Step 10: Prepare Buttercream

In a stand mixer fitted with the paddle attachment or using a handheld mixer, beat salted butter until smooth. Gradually mix in blackberry preserves until fully combined.

Step 11: Add Sugar

While mixing on low speed, add spoonfuls of powdered sugar gradually until fully incorporated. Then mix in vanilla extract, salt, and dried thyme.

Step 12: Whip Until Fluffy

Increase mixer speed to medium and beat for about four to five minutes until very light and fluffy. Scrape down sides as needed during mixing.

Step 13: Level Cake Layers

If necessary, slice off the domed top of one cake layer using a serrated knife to create an even surface while leaving the other layer domed for height.

Step 14: Assemble Cake

Place the leveled cake layer cut side up on your stand or platter. Spread some buttercream in between layers then add blackberry preserves before placing the second layer on top.

Step 15: Frost Top Layer

Pipe or spread remaining buttercream on top of your cake as desired. Add another spoonful of blackberry preserves into the middle before garnishing with fresh blackberries and chopped pistachios if you wish.

Common Mistakes to Avoid

• Overmixing the batter – Mix the ingredients just until combined to prevent a dense cake. Overmixing can develop gluten and alter the cake’s softness.
