Ingredients

Scale
  • 2 ½ cups (312 grams) all-purpose flour
  • 2 ½ tsp (12 grams) baking powder
  • ½ tsp (2 grams) baking soda
  • ½ tsp (3 grams) salt
  • 1 cup (227 grams) unsalted butter, softened
  • 1 ¾ cups (350 grams) granulated sugar
  • 4 large eggs, room temperature
  • 2 tsp (10 ml) pure vanilla extract
  • 1 cup (240 ml) buttermilk, room temperature
  • 1 cup (227 grams) unsalted butter, softened (for buttercream)
  • 3 cups (360 grams) powdered sugar, sifted
  • 2 tbsp (30 ml) heavy cream
  • 1 tsp (5 ml) pure vanilla extract (for buttercream)
  • Pinch of salt (for buttercream)
  • About 1 lb (450 grams) white fondant
  • Edible shimmer dust (white or silver)
  • Cornstarch or powdered sugar (for dusting and rolling fondant)
  • Gel food coloring (optional, tiny drop of gray or blue)

Instructions

  1. Preheat oven to 350°F (175°C). Grease two 8-inch cake pans and line bottoms with parchment paper.
  2. In a medium bowl, sift together flour, baking powder, baking soda, and salt. Set aside.
  3. In a large bowl, beat softened butter and granulated sugar on medium speed for 4-5 minutes until light and fluffy.
  4. Add eggs one at a time, beating well after each addition. Stir in vanilla extract.
  5. Alternately add dry ingredients and buttermilk to butter mixture in three additions, starting and ending with dry ingredients. Mix gently on low speed until just combined.
  6. Divide batter evenly between prepared pans and smooth tops with a spatula.
  7. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Let cool in pans for 10 minutes, then transfer to cooling racks to cool completely.
  8. For buttercream, beat softened butter until creamy. Gradually add sifted powdered sugar, alternating with heavy cream and vanilla extract. Beat on high for 3-4 minutes until fluffy. Adjust consistency with cream if needed.
  9. Place one cake layer on serving plate. Spread an even layer of buttercream over the top. Add second cake layer and cover entire cake with a thin crumb coat of buttercream. Chill in fridge for 20 minutes.
  10. Dust work surface with cornstarch. Roll out white fondant to about 1/8-inch (3 mm) thick. Cut into triangular mountain shapes. Use fingers or fondant tool to add gentle ridges mimicking mountain textures.
  11. Carefully place fondant peaks around cake, layering as desired. Use a little water or edible glue to stick pieces together. Brush peaks lightly with edible shimmer dust.
  12. Let cake sit at room temperature for 30 minutes before serving to soften fondant slightly and meld flavors.

Notes

Keep hands and work surface lightly dusted with cornstarch to prevent fondant sticking. Chill fondant if too sticky. Chill crumb coat to trap crumbs and ensure smooth final frosting. Use gentle pressure to create natural ridges on fondant peaks. Fondant can dry out if left uncovered; store cake covered tightly.
