Method
- Preheat oven to 350°F (175°C). Grease a 9-inch pan and line with parchment paper.
- Grind pistachios in a food processor to a fine, flour-like consistency. Do not over-process.
- Whisk together flour, baking powder, and salt in a medium bowl.
- Cream butter, oil, sugar, and lemon zest for 3–4 minutes until light and fluffy.
- Add eggs one at a time, then egg white, beating 30 seconds after each.
- Mix in sour cream, vanilla, and almond extract just until combined.
- Alternate adding flour mixture and buttermilk, beginning and ending with flour. Mix gently.
- Fold in ground pistachios gently with a spatula.
- In a separate bowl, beat cream cheese until smooth. Add egg, vanilla, and powdered sugar until silky.
- Spread cake batter into prepared pan. Top evenly with cream cheese mixture.
- Bake for 40–45 minutes until edges are golden and center jiggles slightly.
- Cool for 15 minutes, then chill for at least 2 hours before serving.
Notes
This cake improves after 24 hours as flavors meld. Add cranberries and orange zest for holidays or chocolate chips for variation. For gluten-free, use a GF flour blend with xanthan gum. Avoid overbaking for best gooey texture.
