Ingredients

Salted Caramel

  • 140 g granulated sugar
  • 1 1/2 tbsp water
  • 40 g butter
  • 150 g heavy cream
  • big pinch of salt

Vanilla Cake Layers

  • 340 g all-purpose flour
  • 2 tbsp cornstarch
  • 3/4 tsp baking powder
  • 3/4 tsp baking soda
  • 3/4 tsp salt
  • 180 g butter, room temperature
  • 300 g granulated sugar
  • 4 large eggs, room temperature
  • 240 g sour cream (14-18%), room temperature
  • 60 g vegetable oil (e.g., canola oil)
  • 2 tsp vanilla extract

Caramel Buttercream

  • 400 g butter, room temperature
  • 660 g powdered sugar
  • 2 tsp vanilla extract
  • 2-3 tbsp caramel (prepared from salted caramel sauce)


Instructions

  1. Prepare Salted Caramel: In a medium saucepan, combine granulated sugar and water, stirring until all sugar is wet and spread evenly. Heat over medium-high heat, melting sugar until golden brown, stirring occasionally for even melting.
  2. Incorporate Butter and Cream: Reduce heat to medium; add butter and stir until melted and incorporated. Gradually add heavy cream, stirring continuously to combine despite vigorous bubbling. Stir constantly until mixture thickens slightly.
  3. Season and Cool Caramel: Turn off heat, stir in a big pinch of salt. Transfer caramel to a shallow bowl and refrigerate for 30-60 minutes until it cools to room temperature.
  4. Preheat Oven and Prepare Pans: Set oven to 170ºC (340ºF) conventional. Line three 20 cm baking pans with parchment paper.
  5. Sift Dry Ingredients: Sift together all-purpose flour, cornstarch, baking powder, baking soda, and salt; set aside.
  6. Cream Butter and Sugar: In a large mixing bowl, beat butter and granulated sugar on high speed for 3 minutes until fluffy.
  7. Add Eggs: Add eggs two at a time, mixing well after each addition until fully incorporated.
  8. Add Dry Ingredients and Wet Ingredients: Add half of the dry mixture on low speed, mixing until just combined. Next, add sour cream, vegetable oil, and vanilla extract; mix until just combined. Then add remaining dry ingredients and mix until combined.
  9. Fold Batter: Use a rubber spatula to gently fold the batter to ensure all ingredients are evenly combined without overmixing.
  10. Divide and Bake: Evenly distribute batter into prepared pans. Bake for 19-22 minutes or until a cake tester inserted in the center comes out clean. Cakes should remain light in color and not brown.
  11. Cool Cakes: Allow cakes to cool on a wire rack. After 10 minutes, carefully remove from pans and cool completely.
  12. Prepare Buttercream: Sift powdered sugar and set aside. Beat butter in a stand mixer or using a hand mixer for 4 minutes on medium-high speed, scraping down sides, then beat for another 2 minutes.
  13. Incorporate Sugar and Flavorings: Add powdered sugar, vanilla extract, and 2-3 tablespoons of prepared caramel in two parts, whipping thoroughly with each addition until fully incorporated.
  14. Final Buttercream Mix: Scrape sides of bowl again and mix buttercream on low speed for 1 minute for smooth consistency.
  15. Assemble Cake: Place first cake layer on serving plate or turntable. Spread 2 large scoops of buttercream evenly with an offset spatula, then drizzle 2-3 tbsp of caramel, spreading evenly leaving edges free to prevent caramel overflow. Repeat for second layer. Add final cake layer and cover entire cake in a thin crumb coat.
  16. Chill Cake: Refrigerate cake for 20 minutes to firm crumb coat, making final frosting easier.
  17. Final Frosting and Caramel Decoration: Apply remaining buttercream evenly over cake. Drizzle remaining caramel on top, swirling it into the buttercream if desired for decoration.

Notes

  • Ensure all wet ingredients (butter, eggs, sour cream) are at room temperature to achieve smooth batter and evenly baked cake layers.
  • Be cautious when adding heavy cream to hot caramel as it will bubble vigorously.
  • Do not overmix cake batter to maintain light and fluffy cake texture.
  • Use a light hand while folding to avoid deflating the batter.
  • Allow caramel sauce to cool to room temperature before mixing into buttercream to prevent melting the frosting.
  • The cake layers will remain light in color and should not brown; watch baking time carefully.
  • Chilling the cake after crumb coating makes final frosting application cleaner and easier.
