INGREDIENT NOTES

Key ingredients to note. For the complete list and exact quantities, see the recipe card below.

  • All-purpose flour: Use flour with 10–11% protein for a light, airy crumb.
  • Granulated sugar: Sweetens the cake and is the base for the caramel.
  • Baking powder & baking soda: Give lift and a tender texture.
  • Salt: Enhances all flavors—especially caramel.
  • Eggs: Bring to room temperature before baking for best volume.
  • Oil: Use a neutral-flavored oil like canola for moisture without flavor interference.
  • Sour cream: Adds moisture and stability to the crumb.
  • Butter: Use room-temperature butter for the buttercream to ensure a smooth texture.

STEP BY STEP INSTRUCTIONS – CARAMEL AND CAKE LAYERS

This recipe requires a stand mixer with a paddle attachment or a hand mixer. You will also need three 20 cm (8 in) cake pans lined with parchment paper. Preheat the oven to 170ºC (340ºF) for a conventional oven.

SALTED CARAMEL

Step 1: In a medium saucepan combine the granulated sugar and water, stirring until the sugar is evenly moistened. Spread it into an even layer so it melts uniformly. Heat over medium–high until the sugar reaches a golden brown.

Step 2: Lower the heat to medium and stir in the butter until melted. Gradually add the heavy cream a little at a time, stirring after each addition—the mixture will bubble vigorously, so take care.

Step 3: Remove from heat, stir in a pinch of salt, then transfer to a shallow bowl and chill until cooled. This usually takes 30–60 minutes.

Step 4: Sift the dry ingredients together and set aside. In a mixer bowl, beat the butter and granulated sugar on high for about 3 minutes until light and fluffy.

Step 5: Add the eggs two at a time, mixing until incorporated. Add half the dry ingredients on low speed and mix until just combined.

Step 6: Mix in the sour cream, vegetable oil and vanilla extract until just combined, then add the remaining dry ingredients and mix until combined. Use a spatula to gently fold the batter to ensure everything is evenly mixed.

Step 7: Divide the batter among the prepared pans and bake for 19–23 minutes or until a cake tester comes out clean. Allow cakes to cool in the pans for about 10 minutes, then transfer to a wire rack to cool completely.

STEP BY STEP INSTRUCTIONS – CARAMEL FROSTING AND ASSEMBLING

CARAMEL BUTTERCREAM

Step 1: Sift the powdered sugar and set aside. In a mixer, beat the butter on medium–high for 4 minutes, scrape the bowl, then beat for 2 more minutes.

Step 2: Add the powdered sugar, vanilla and caramel in two additions, whipping until each addition is fully incorporated. Scrape the bowl and mix on low for 1 minute to finish.

ASSEMBLING

Step 3: Place the first cake layer on your serving plate or cake board. Add two generous scoops of buttercream and spread evenly. Spoon 2–3 tablespoons of cooled salted caramel over the buttercream, keeping the caramel away from the outer edge so it won’t run.

Step 4: Repeat with the next layer, then top with the final layer. Apply a thin crumb coat over the entire cake and refrigerate for 20 minutes to set.

Step 5: Finish with the remaining buttercream, smooth the sides and top, and drizzle more caramel over the cake as desired. Optionally finish with a sprinkle of flaky sea salt for decoration.

EXPERT BAKING TIPS

  • Use a kitchen scale: Weighing ingredients in grams is the most accurate way to reproduce results—highly recommended.
  • Don’t overmix: Finish with a gentle fold using a spatula to incorporate any remaining ingredients without developing gluten.
  • Light vs. dark pans: Light-colored aluminum pans bake more gently and help produce a softer, evenly baked cake. Dark pans absorb more heat and can brown the crust faster, which may dry the cake.

FAQ

Can I replace the sour cream with something else?

Yes. Substitute full-fat Greek yogurt 1:1 for the sour cream.

Can it be made a day ahead?

Yes. Make the caramel, cake layers and buttercream the day before. Wrap cake layers in plastic wrap and store at room temperature out of direct sunlight. Store caramel and buttercream tightly covered in the fridge; bring the buttercream to room temperature and re-whip before assembling.

How do I know when cake layers are done?

Insert a cake tester or toothpick into the center; when it comes out clean with no wet batter, the cake is done.

HOW TO STORE

Store the assembled cake in the refrigerator in an airtight container. Allow slices to come to room temperature before serving for the best texture. Consume within a few days for optimal freshness.
