Step-by-Step Directions

Making the Caramel Sauce:

Heat the sugar in a heavy-bottomed saucepan over medium heat, stirring constantly with a heat-resistant spatula. The sugar will clump, then melt into an amber liquid—this takes about 8-10 minutes.
Once the sugar reaches a deep amber color, immediately add the butter pieces. The mixture will bubble vigorously—keep stirring until the butter is completely melted.
Slowly pour in the heavy cream while stirring constantly. The mixture will bubble up again. Continue stirring until smooth.
Remove from heat and stir in vanilla and salt. Let cool completely before using. You’ll have about 1¼ cups of caramel sauce.

Pro Tip: Watch the sugar carefully—it can go from perfect to burnt quickly! If you see any black spots, start over. The caramel is ready when it smells nutty and rich.

Preparing the Cake:

Preheat your oven to 350°F (175°C). Grease two 9-inch round cake pans and line with parchment paper. Dust lightly with flour.
Cream the softened butter with both sugars using an electric mixer on medium speed for 4-5 minutes until light and fluffy.
Beat in eggs one at a time, making sure each is fully incorporated. Add vanilla and ½ cup of cooled caramel sauce.
In a separate bowl, whisk together flour, baking powder, and salt.
Alternate adding the dry ingredients and milk to the butter mixture, beginning and ending with flour. Mix on low speed just until combined.

Pro Tip: Don’t overmix the batter once you add the flour—this can make the cake tough. Stop mixing as soon as you don’t see streaks of flour.

Divide batter evenly between prepared pans. Smooth the tops with an offset spatula.
Bake for 28-32 minutes or until a toothpick inserted in the center comes out with just a few moist crumbs.
Cool in pans for 15 minutes, then turn out onto wire racks. Cool completely before frosting.

Making the Salted Caramel Frosting:

Beat the softened butter and cream cheese together until smooth and creamy, about 3-4 minutes. Scrape down the bowl as needed.
Gradually add powdered sugar, beating on low speed initially, then increasing to medium-high speed until fluffy.
Beat in ¾ cup of caramel sauce until well combined. If the frosting seems too thick, add heavy cream one tablespoon at a time until you reach the perfect spreading consistency.

Pro Tip: The frosting should hold its shape but spread easily. If it’s too soft, chill for 20 minutes before using.

Assembling the Cake:

Level the cake layers if needed using a serrated knife. Place the first layer on your serving plate.
Spread about 1 cup of frosting over the first layer, leaving a small border around the edges.
Add the second layer and gently press down. Frost the top and sides with remaining frosting, using smooth, even strokes.
Drizzle with extra caramel sauce and sprinkle with flaky sea salt just before serving.

Expert Tips for Success

Storage Wisdom:

Store covered at room temperature for up to 2 days, or refrigerated for up to 5 days
Bring refrigerated cake to room temperature 1 hour before serving for best flavor
The caramel sauce can be made up to 1 week ahead and stored in the refrigerator

Flavor Enhancement Ideas:

Add a tablespoon of bourbon to the caramel sauce for depth
Fold chopped toasted pecans into the cake batter for crunch
Try adding a layer of caramel sauce between the cake layers for extra richness

Baking Success Secrets:

Make sure your caramel sauce is completely cool before adding to the cake batter
Room temperature ingredients mix more easily and create better texture
Don’t skip the parchment paper—caramel can make cakes stick to pans

Make-Ahead Magic: The cake layers can be baked up to 2 days ahead and stored wrapped at room temperature. The caramel sauce keeps well in the fridge for a week—just warm it slightly before drizzling. The frosting can be made a day ahead; let it come to room temperature and re-whip before using.

Troubleshooting Tips:

If your caramel crystallizes, add a tablespoon of corn syrup next time to prevent this
Grainy frosting usually means the powdered sugar wasn’t sifted—always sift for smoothness
If the cake layers dome too much, lower your oven temperature by 25°F next time

Common Questions

Can I use store-bought caramel sauce instead of homemade?

You can, but homemade tastes significantly better and you can control the salt level. If using store-bought, choose a high-quality thick caramel sauce and taste-test the frosting as you go.

Why did my caramel sauce turn out grainy?

This usually happens when the sugar crystallizes. Make sure your pan and utensils are completely clean, and avoid stirring too vigorously once the sugar starts melting. Adding a tablespoon of corn syrup can help prevent crystallization.

How do I fix frosting that’s too sweet?

Add a pinch more salt to balance the sweetness, or incorporate a tablespoon of cream cheese to cut through the sugar. You can also add an extra tablespoon of caramel sauce for depth.

Can I make this as a sheet cake instead?

Absolutely! Use a 9×13 inch pan and bake for 35-40 minutes. You’ll need about half the frosting recipe for a sheet cake.

My frosting is too runny—what went wrong?

This usually happens when the butter or cream cheese is too warm, or if you added too much liquid. Chill the frosting for 30 minutes, then re-whip. You can also gradually add more powdered sugar to thicken.
