Method
- Preheat your oven to 325 degrees Fahrenheit and position the rack in the lower third of the oven.
- Grease your loaf pan or bundt pan generously with cooking spray or butter, then line the bottom with parchment paper for easy release.
- In a small bowl, whisk together the flour, baking powder, baking soda, and salt until evenly combined. Set aside.
- In a large bowl, beat the softened butter and granulated sugar on medium-high speed for 3 to 4 minutes until pale, fluffy, and lighter in color.
- Scrape down the sides of the bowl to ensure even mixing.
- Add the eggs one at a time, beating on medium speed until fully incorporated after each egg, about 30 seconds between additions.
- Pour in the vanilla extract and add the lemon zest if using, then beat for another 30 seconds to combine.
- Reduce the mixer speed to low. Add one-third of the dry ingredients and mix until just combined.
- Add half of the sour cream and mix on low speed until just combined.
- Add another third of the dry ingredients and mix just until combined.
- Add the remaining sour cream and mix on low until barely combined.
- Add the last third of the dry ingredients and mix until just combined.
- Stop the mixer and fold the batter a few times by hand with a rubber spatula to gently bring everything together without deflating the air.
- Pour the batter into the prepared pan and smooth the top with an offset spatula or the back of a spoon.
- Tap the pan gently on the counter three or four times to release any large air bubbles.
- Bake in the preheated oven at 325 degrees Fahrenheit for 55 to 65 minutes, or until a toothpick inserted into the center comes out clean with a few moist crumbs.
- If the top browns too quickly, tent the pan loosely with aluminum foil for the last 15 minutes of baking.
- Remove the cake from the oven and let it cool in the pan for 15 minutes.
- Run a thin knife around the edges of the pan to loosen the cake, then turn it out onto a wire cooling rack.
- Peel away the parchment paper from the bottom if used, and let the cake cool completely on the rack, about 2 hours at room temperature.
Notes
Make sure all ingredients, especially eggs and sour cream, are at room temperature before mixing to ensure smooth emulsion and a tender crumb. Store the cooled cake wrapped tightly in plastic wrap to maintain moisture for up to five days.
