Mastering Butter Cake with Salted Caramel Buttercream Frosting Recipe: How-To

Follow these detailed steps to achieve a stunning butter cake with salted caramel buttercream:
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures your cake bakes evenly.
Step 2: Prepare the Cake Pans
Grease and flour your 9-inch round cake pans. This helps the cake release easily once baked.
Step 3: Combine Dry Ingredients
In a bowl, whisk together 3 cups of all-purpose flour, 2 teaspoons of baking powder, 1 teaspoon of baking soda, and a pinch of kosher salt. Set aside.
Step 4: Cream Butter and Sugar
In a large mixing bowl, beat 1 cup of softened butter and 2 cups of sugar together until light and fluffy, about 3-4 minutes.
Step 5: Add Eggs and Vanilla
Add 4 room-temperature eggs, one at a time, mixing well after each addition. Then, blend in 2 teaspoons of vanilla extract.
Step 6: Mix Dry and Wet Ingredients
Gradually add the dry ingredient mixture to the butter mixture, alternating with 1 cup of room-temperature buttermilk. Start and end with the flour mixture, mixing until just combined.
Step 7: Pour Batter into Pans
Divide the batter evenly between the prepared cake pans, smoothing the tops with a spatula.
Step 8: Bake the Cakes
Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out clean.
Step 9: Cool the Cakes
Once baked, remove the cakes from the oven and let them cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.
Step 10: Make the Salted Caramel Buttercream
In a mixing bowl, combine 1/2 cup of shortening and 1/2 cup of softened butter. Beat until creamy. Gradually add 2 cups of confectioners sugar and mix well. Stir in 1/2 teaspoon of sea salt and adjust to taste.
Step 11: Frost the Cakes
Once the cakes are completely cool, place one layer on a serving plate. Spread a generous amount of salted caramel buttercream on top, then place the second layer on top and frost the top and sides of the cake.
Step 12: Serve and Enjoy
Slice your beautiful butter cake and serve it with a drizzle of additional salted caramel sauce if desired. Enjoy every bite of this indulgent treat!
Texture-Safe Substitutions
If you’re looking to modify the recipe without compromising texture, consider these substitutes:
- For buttermilk, use plain yogurt or a mix of milk with a splash of vinegar.
- Instead of shortening, you can use additional butter for a richer flavor.
- To make it gluten-free, substitute all-purpose flour with a 1:1 gluten-free baking blend.
Insider Tips
- Ensure all your ingredients are at room temperature for the best mixing results.
- Don’t overmix the batter; mix just until combined to keep the cake light and fluffy.
- If your frosting is too thick, add a little milk to achieve the desired consistency.
- For an extra touch, garnish with sea salt flakes on top of the frosting.
Save It for Later
This Butter Cake with Salted Caramel Buttercream Frosting Recipe is perfect for making ahead of time. Here’s how to store it:
- Keep the unfrosted cake layers in an airtight container at room temperature for 2-3 days.
- If you plan to frost it later, store the buttercream in the refrigerator for up to a week. Just rewhip it before using.
- Frosted cakes can be kept in the refrigerator for up to a week, but it’s best served fresh.
Handy Q&A
Can I use a different frosting for this cake?

How do I know when my cake is done baking?

What can I do with leftover salted caramel buttercream?
