Sour Cream Pound Cake

Ingredients

• 8 3/4 ounces sugar
• 4 ounces unsalted butter , about 65°F
• 1 ounce refined coconut oil
• 1/2 teaspoon baking powder
• 1/2 teaspoon Diamond Crystal kosher salt; for table salt, use half as much by volume
• 1 vanilla bean, split and scraped, pod reserved for another use
• 3 large eggs, brought to about 65°F
• 7 1/2 ounces all-purpose flour, such as Gold Medal , plus more for dusting pan
• 1/2 ounce vanilla extract
• 5 ounces sour cream

Directions

1. Adjust oven rack to lower-middle position and preheat to 375 degrees F (190 degrees C). Lightly grease a 1-pound aluminum loaf pan and dust with flour. In the bowl of a stand mixer fitted with a paddle attachment, combine sugar, butter, coconut oil, baking powder, salt, and vanilla seeds. Mix on low to combine, then increase to medium and cream until fluffy and light, about 5 minutes. About halfway through, pause to scrape bowl and beater with a flexible spatula.
2. With mixer still running, add eggs one at a time, letting each fully incorporate before adding the next. Reduce speed to low and sprinkle in 1/3 of flour, then add vanilla extract and 1/3 of sour cream. Repeat with remaining flour and sour cream, working in thirds as before.
3. Scrape bowl and beater with a flexible spatula and resume mixing on medium speed for 1 second to ensure everything is well combined. The batter should look creamy and thick, registering around 65 degrees F on a digital thermometer. (Significant deviation indicates ingredients were too warm or too cold, which can lead to textural problems with the cake.)
4. Scrape into prepared pan and bake until crust is golden (although the interior of the split crown will be quite pale), about 55 minutes or to an internal temperature of 200 degrees F (93 degrees C). Cool cake to about 90 degrees F (32 degrees C), then loosen with a butter knife and remove from pan. Wrap tightly in plastic and continue cooling until no trace of warmth remains, about 3 hours. Slice with a chef's knife and serve plain, with ice cream, or with fruity whipped cream and fresh fruit.
