Description
This classic buttermilk cake features a tender, velvety crumb and a delicate tang, perfectly paired with a rich vanilla buttercream. It is an ideal foundational recipe for any home baker looking to master the science of structural baking through precise measurement and proper emulsification.
Ingredients
- 2 1/2 cups cake flour
- 1 cup unsalted butter, softened
- 1 1/2 cups granulated sugar
- 3 large eggs, room temperature
- 1 cup buttermilk, room temperature
- 1 tsp baking soda
- 1 tsp baking powder
- 1/2 tsp kosher salt
- 2 tsp vanilla extract
- 2 cups powdered sugar (for frosting)
- 1/4 cup milk (for frosting)
Instructions
- Prepare cake pans. Butter two nine-inch round cake pans, line with parchment, butter the parchment, and dust with cake flour. Preheat oven to 350°F.
- Sift dry ingredients. Double-sift the cake flour, then whisk together with baking powder, baking soda, and kosher salt in a medium bowl.
- Cream butter mixture. Beat softened butter and sugar in a stand mixer on medium speed for two minutes until pale and fluffy, scraping down the sides as needed.
- Emulsify with eggs. Add eggs one at a time, beating for one full minute after each addition to ensure a stable, shiny emulsion.
- Combine batter ingredients. Alternately stir in the flour mixture and room-temperature buttermilk in three additions, ending with flour, and add vanilla just before stopping the mixer.
- Bake the layers. Divide batter into prepared pans and bake for 30 to 33 minutes until the edges pull away from the pan sides.
- Cool completely. Rest cakes in the pans for 20 minutes, then invert onto a wire rack to cool fully before frosting.
- Prepare the frosting. Beat butter and salt until smooth, then gradually incorporate powdered sugar and milk, whipping for three minutes until light and airy.
- Assemble the cake. Frost the top of the first layer, stack the second layer, and coat the top and sides of the entire cake with the remaining buttercream.
Notes
- Ensure all ingredients are at room temperature to prevent the batter from curdling during the mixing process.
- Weighing flour on a digital scale is highly recommended to avoid the density caused by over-packing measuring cups.
- Avoid opening the oven door during the first 25 minutes of baking to prevent the delicate cake structure from collapsing.
- If the frosting appears too soft due to ambient kitchen heat, chill the bowl for ten minutes to firm up the fats before final assembly.
