Ingredients

Scale
  • 2 ½ cups (312 grams) all-purpose flour
  • 2 ½ teaspoons baking powder
  • ½ teaspoon salt
  • 1 cup (227 grams) unsalted butter, softened
  • 1 ¾ cups (350 grams) granulated sugar
  • 4 large eggs, room temperature
  • 1 cup (240 ml) whole milk, room temperature (can substitute almond milk for dairy-free)
  • 2 teaspoons pure vanilla extract
  • For the Buttercream Frosting:
  • 1 cup (227 grams) unsalted butter, softened
  • 4 cups (480 grams) powdered sugar, sifted
  • 2–3 tablespoons (30–45 ml) heavy cream
  • 1 ½ teaspoons pure vanilla extract
  • Pinch of salt
  • Food coloring gels (optional)
  • For Decorations:
  • Graduation cake toppers (caps, scrolls, 2026 numbers) or edible glitter
  • Fresh berries or sprinkles
  • Edible gold dust or shimmer spray (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour two 8-inch cake pans or line with parchment paper.
  2. In a medium bowl, sift together flour, baking powder, and salt. Set aside.
  3. Using a mixer, beat softened butter and granulated sugar on medium speed until light and fluffy, about 3-5 minutes.
  4. Add eggs one at a time, beating well after each addition.
  5. Alternate adding dry ingredients and milk to the butter mixture, starting and ending with dry ingredients. Mix gently on low speed until just combined.
  6. Fold in vanilla extract with a spatula.
  7. Divide batter evenly between prepared pans and smooth tops.
  8. Bake for 25-30 minutes or until a toothpick inserted comes out clean. Rotate pans halfway through baking.
  9. Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely.
  10. Prepare buttercream frosting by beating softened butter until creamy. Gradually add powdered sugar on low speed. Add heavy cream, vanilla, and salt, then beat on medium-high until light and fluffy.
  11. Place one cake layer on serving plate. Spread frosting evenly on top. Add second layer and apply a thin crumb coat. Chill for 20 minutes.
  12. Apply final thick layer of frosting, smoothing with an offset spatula.
  13. Decorate with piping bags, graduation toppers, sprinkles, or edible glitter as desired.
  14. Refrigerate finished cake for 30 minutes before serving. Bring to room temperature 20 minutes before slicing.

Notes

Use room temperature ingredients for best results. Do not overmix batter to avoid dense cake. Chill cake after crumb coating to prevent crumbs in final frosting. Add gel food coloring gradually to avoid thinning frosting. Bring cake to room temperature before slicing for best texture. Can substitute almond milk for dairy-free or use gluten-free flour blend for gluten-free version.
