Instructions
Preparation
- Preheat your oven to 350°F (175°C). Grease two 6-inch or 7-inch cake pans with butter, dust them with flour, and line the bottoms with parchment paper rounds.
- In a medium bowl, whisk together the milk and apple cider vinegar or lemon juice. Allow this mixture to sit for 5 minutes to create a homemade buttermilk.
- Pulse the pistachios and granulated sugar in a food processor until finely ground. In a separate bowl, whisk together the pistachio-sugar mixture, flour, baking powder, and salt.
Mixing and Baking
- Combine the buttermilk mixture, olive oil, vanilla extract, and almond extract in a large bowl. Optionally, add a few drops of green food dye.
- Gently fold the dry ingredients into the wet mixture until just combined. Avoid overmixing.
- Divide the batter evenly between the prepared pans. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.
- Let the cakes cool completely on a wire rack. For optimal flavor, wrap and chill the layers overnight.
Frosting and Assembly
- Beat the salted butter and blackberry preserves until smooth. Gradually add powdered sugar, mixing on low until fully incorporated.
- Add vanilla extract, salt, and dried thyme, and beat on medium for 4-5 minutes until light and fluffy.
- Level the top of one cake layer and place it cut side up on a stand. Spread a layer of buttercream and blackberry preserves in the center.
- Carefully place the second cake layer on top and spread remaining buttercream. Garnish with blackberries and chopped pistachios.
- Slice and enjoy this delicious cake.
Notes
Ensure all ingredients are fresh for the best results. Chilling the layers enhances flavor and eases frosting. Variations can include substituting nuts or adding flavor extracts like lemon or orange.
