Granny’s Five-Flavor Pound Cake

Nonstick baking spray

• 2 1/2 cups/330 grams all-purpose flour
• 1/2 cup/60 grams cornstarch (or an additional 1/4 cup/33 grams all-purpose flour)
• 1 teaspoon baking powder
• 1 teaspoon fine salt
• 1 cup/228 grams unsalted butter, cut into tablespoons, at room temperature
• 2 1/2 cups/500 grams granulated sugar
• 6 large eggs, at room temperature
• 1 cup/244 grams sour cream, at room temperature
• 1 teaspoon vanilla extract
• 1 teaspoon rum extract
• 1 teaspoon coconut extract
• 1 teaspoon lemon extract
• 1 teaspoon almond extract

1. Heat the oven to 325 degrees. Spray a 10-cup Bundt or tube pan with nonstick baking spray.
2. Whisk the flour, cornstarch, baking powder and salt in a bowl.
3. In the bowl of a stand mixer fitted with a paddle, beat the butter and sugar on medium-high speed until pale and fluffy, about 3 minutes. Stop and scrape down the sides and bottom of the bowl. With the mixer on medium, add the eggs one at a time, completely incorporating each egg before adding the next. Stop and scrape down the bowl.
4. With the mixer on low speed, add about a third of the flour. Once incorporated, add half of the sour cream, then half of the remaining flour. Beat in the rest of the sour cream and the remaining flour, then continue beating for 2 minutes on medium speed, stopping occasionally to scrape the sides and bottom of the bowl. Add the extracts one at a time, completely incorporating each before adding the next. Continue beating until the batter is shiny, about 4 minutes. Pour the batter into the cake pan.
5. Bake until the cake is golden and a skewer inserted in the center comes out clean, 60 to 70 minutes. It will smell really, really good.
6. Let the cake cool in the pan on a wire rack for 10 minutes, then unmold onto the rack. Let the cake cool completely. Well-wrapped, the cake will keep in an airtight container at room temperature for up to 1 week or in the freezer for up to 3 months.
