Ingredients

Scale

2.5 cups all-purpose flour
1.5 cups granulated sugar
1 tablespoon baking powder
0.5 teaspoon salt
1 cup unsalted butter, softened
1 cup whole milk, at room temperature
2 large eggs, at room temperature
2 teaspoons pure vanilla extract
1 cup unsalted butter, softened
4 cups powdered sugar, sifted
2 tablespoons whole milk or heavy cream
2 teaspoons pure vanilla extract
Pinch salt

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans or line them with parchment paper circles
  2. In a large bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt
  3. In a separate medium bowl, whisk together the whole milk, large eggs, and pure vanilla extract
  4. In the bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer), cream the softened unsalted butter until light and fluffy, about 2-3 minutes. Gradually add the granulated sugar and beat on medium-high speed for another 3-5 minutes, until the mixture is pale and airy. Scrape down the sides of the bowl ofte
  5. With the mixer on low speed, slowly add about one-third of the dry ingredients to the butter mixture, mixing until just combined. Next, pour in half of the wet ingredients, mixing until incorporated. Repeat this process, ending with the remaining dry ingredients. Do not overmix; mix until just combined and smooth
  6. Divide the batter evenly between your two prepared cake pans. Smooth the tops with a spatula
  7. Bake for 28-32 minutes, or until a wooden skewer inserted into the center of the cake comes out clean. The top should be golden brown and spring back when gently pressed
  8. Remove the cakes from the oven and let them cool in their pans on a wire rack for 10-15 minutes. Then, carefully invert the cakes onto the wire rack to cool completely
  9. In the bowl of a stand mixer with the paddle attachment (or using a hand mixer), beat the softened unsalted butter on medium speed until creamy, about 2 minutes
  10. Gradually add the sifted powdered sugar, one cup at a time, mixing on low speed until combined, then increasing to medium-high
  11. Add 2 tablespoons of milk or cream, pure vanilla extract, and a pinch of salt. Beat on medium-high speed for 3-5 minutes until the frosting is light, fluffy, and smooth. If the frosting seems too thick, add more milk or cream one teaspoon at a time until you reach your desired consistency
  12. Once the cake layers are completely cool, level them if necessary using a serrated knife
  13. Place one cake layer on your serving plate or cake stand. Spread about 1 cup of buttercream evenly over the top
  14. Carefully place the second cake layer on top
  15. Apply a thin layer of frosting all over the cake (top and sides) – this is your "crumb coat." Refrigerate for 15-20 minutes to set the crumb coat
  16. After chilling, apply the remaining buttercream frosting generously over the entire cake. Use an offset spatula or bench scraper to smooth the sides and top for a polished look
  17. Decorate your Sweet 16 Birthday Cake as desired!

Notes

Always bring your butter, eggs, and milk to room temperature before baking to help them emulsify better, creating a smoother batter and a more uniform cake texture.

Do not overmix the batter once dry ingredients are added; overmixing develops gluten, leading to a tough, dry cake.

Allow cake layers to cool completely on a wire rack for a couple of hours before frosting to prevent the frosting from melting.

Apply a thin crumb coat of frosting and chill for 15-20 minutes to trap loose crumbs, ensuring a smooth final finish.

Sift powdered sugar for the smoothest, lump-free buttercream.
