The Science of Salted Caramel
Before we dive into the recipe, let’s appreciate why this combination works so magically:
- Flavor Contrast – Salt suppresses bitterness while enhancing sweetness
- Texture Play – Smooth caramel against crunchy salt flakes
- Chemical Magic – Salt actually makes caramel taste sweeter by blocking bitter receptors
Ingredients Breakdown
For the Brown Sugar Cake Layers:
- 3 cups (360g) cake flour (or all-purpose flour + 2 tbsp cornstarch)
- 1 tbsp baking powder
- 1 tsp fine sea salt
- 1 cup (226g) unsalted butter, room temperature
- 2 cups (400g) dark brown sugar (packed)
- 4 large eggs, room temperature
- 1 tbsp vanilla extract
- 1½ cups (360ml) buttermilk
For the Salted Caramel Sauce:
- 1 cup (200g) granulated sugar
- 6 tbsp (85g) unsalted butter, cubed
- ½ cup (120ml) heavy cream, warmed
- 1-2 tsp flaky sea salt (to taste)
For the Caramel Buttercream:
- 1½ cups (340g) unsalted butter, room temperature
- 4-5 cups (480-600g) powdered sugar
- ½ cup salted caramel sauce (from above)
- 2 tsp vanilla extract
- 2-4 tbsp heavy cream (as needed)
Step-by-Step Instructions
Day 1: Make the Caramel Sauce
- Melt sugar in a light-colored saucepan over medium heat, swirling occasionally (don’t stir!) until deep amber.
- Add butter – whisk vigorously (mixture will bubble violently).
- Slowly drizzle cream while whisking constantly.
- Finish with salt and cool completely before using.
Pro Tip: Make extra – you’ll want to drizzle it on everything!
Day 2: Bake the Cake Layers
- Preheat oven to 350°F (175°C). Grease and line three 8-inch pans.
- Whisk dry ingredients – flour, baking powder, and salt.
- Cream butter and sugar for 5 minutes until light and fluffy.
- Add eggs one at a time, then vanilla.
- Alternate dry ingredients with buttermilk in 3 additions.
- Bake 22-25 minutes until a toothpick comes out clean.
- Cool completely before assembling.
Assembly Masterclass
- Level cakes if needed using a serrated knife.
- First layer: Cake → ¾ cup buttercream → caramel drizzle
- Repeat for second layer
- Crumb coat the entire cake and chill 30 minutes
- Final frost with remaining buttercream
- Decorate with caramel drip, salt flakes, and optional garnishes
Professional Techniques for Home Bakers
The Perfect Caramel Drip
- Temperature test: Caramel should coat a spoon but still be pourable
- Practice first: Test drips on an inverted glass
- Timing matters: Apply when cake is chilled but caramel is warm
Buttercream Texture Control
- Too stiff? Add cream 1 tbsp at a time
- Too soft? Chill for 15 minutes then re-whip
- Grainy? The caramel may have been too hot when added
Flavor Variations
🍫 Chocolate-Caramel – Add ½ cup cocoa powder to dry ingredients
☕ Espresso-Caramel – Dissolve 1 tbsp instant espresso in buttermilk
🌰 Praline – Fold 1 cup toasted pecans into frosting
Troubleshooting Guide
Problem | Solution
Caramel crystallizes | Use clean utensils, don’t stir while melting
Cake layers dome | Use baking strips or trim after cooling
Buttercream splits | Warm bowl slightly and re-whip
