  • 12–15 tablespoons heavy cream

Instructions

  1. Preheat oven to 350°F (175°C) and grease three 9-inch round cake pans.
  2. For the vanilla cake layer, cream together butter and sugar until fluffy. Add eggs one at a time, then vanilla extract and yogurt. Mix dry ingredients separately, then add to the wet ingredients alternating with buttermilk.
  3. For the strawberry cake layer, grind freeze-dried strawberries. Cream butter and sugar, add eggs, vanilla, yogurt, and strawberry powder. Mix dry ingredients and alternate with buttermilk.
  4. For the chocolate cake layer, cream butter and both sugars. Add eggs, vanilla, and yogurt. Combine dry ingredients including cocoa powders and espresso. Mix with buttermilk alternately.
  5. Pour each batter into its own pan and bake each for 30 minutes, or until a toothpick comes out clean. Let cool in pans for 10 minutes, then transfer to a cooling rack.
  6. To make the buttercream, beat softened butter until creamy. Gradually add powdered sugar, vanilla extract, and heavy cream until smooth. Divide into three portions if desired to match each cake flavor.
  7. Level cake layers if needed. Place one layer on a cake stand, frost, then stack the next. Repeat for all layers and finish by frosting the outside of the cake.
  8. Chill for 30 minutes before slicing for cleaner cuts.

Notes

  • Use room temperature ingredients for better mixing and texture.
  • Don’t overmix the batter—combine just until incorporated.
  • A kitchen scale can help divide batter evenly across pans.
  • Refrigerating before slicing makes cleaner presentation.
  • Customize with sprinkles, chocolate shavings, or flavored frostings.
