What Kind of Caramel Should I Use?

For this frosting, homemade caramel is the absolute best if you have the time. It adds a deep, buttery richness that store-bought varieties can’t quite match. But don’t worry — if you’re in a pinch, a high-quality jarred caramel sauce will still deliver delicious results. Just make sure it’s thick and not too runny, or it might mess with the frosting texture.

Options for Substitutions

• Butter: You can use vegan butter if you need a dairy-free version, but choose one with a solid consistency (not spreadable).
• Salt: Flaky sea salt brings out the best contrast. If using regular salt, reduce the amount slightly.
• Caramel Sauce: Swap in dulce de leche for a more subtle, creamy flavor.
• Powdered Sugar: For a slightly less sweet version, try replacing 1 cup of powdered sugar with ¾ cup of sifted coconut sugar blended into powder.

Ingredients for this Salted Caramel Buttercream Frosting

• Unsalted Butter – The base of the frosting. It gives a creamy, rich texture and allows other flavors to shine. Room temperature is essential for smooth mixing.
• Powdered Sugar – Sweetens the frosting and provides structure. It also helps achieve the fluffy consistency.
• Salted Caramel Sauce – The heart of the flavor. Homemade or high-quality store-bought, it infuses the frosting with deep, buttery sweetness.
• Vanilla Extract – Adds a warm, aromatic depth that complements the caramel perfectly.
• Sea Salt Flakes – A finishing touch that amplifies flavor and gives that signature salted caramel punch.

Step 1: Soften the Butter

Start by taking your butter out of the fridge well in advance. It should be soft but not melted — think of the texture of room-temperature cream cheese. This is key to getting that whipped, airy texture in the final frosting.

---

Step 2: Whip the Butter

Using a stand mixer or hand mixer, beat the butter on medium-high speed for about 3-5 minutes. You want it light, pale, and fluffy. This step introduces air and sets the foundation for a smooth frosting.

---

Step 3: Add Powdered Sugar Gradually

Lower the mixer speed and add the powdered sugar 1 cup at a time. Mix each addition until fully combined before adding more. Scrape down the sides of the bowl regularly to ensure even blending.

---

Step 4: Mix in the Caramel Sauce

Pour in the salted caramel sauce (cooled if it’s homemade). Beat on medium speed until it’s fully incorporated. Taste the frosting — this is where that deep caramel flavor should start to shine.

---

Step 5: Add Vanilla Extract

Add a teaspoon of pure vanilla extract. Mix for another 30 seconds until it blends in. This rounds out the flavor and enhances the overall sweetness.

---

Step 6: Adjust Consistency (If Needed)

If the frosting is too thick, add 1 tablespoon of heavy cream or milk at a time until you reach your desired consistency. For thicker frosting (for piping), add a bit more powdered sugar.

---

Step 7: Finish with Sea Salt

Sprinkle in a small pinch of flaky sea salt and give the frosting one final gentle mix. Don’t overbeat at this stage — you want the salt to stay a little distinct.

---

Step 8: Use or Store

Use the frosting immediately on your cake or cupcakes, or store it in an airtight container. It can sit at room temperature for a few hours or be refrigerated for up to 5 days. Bring to room temperature and re-whip before using.

How Long to Prepare the Salted Caramel Buttercream Frosting

Making this frosting is surprisingly quick, especially if you already have caramel sauce prepared. If you’re using store-bought or pre-made caramel, you can whip this up in about 15 minutes total.

• Prep Time (with ready caramel): 15 minutes – This includes softening the butter, whipping it, and incorporating the ingredients.
• Prep Time (with homemade caramel): Add 20-25 minutes – If you’re making caramel from scratch, be sure to let it cool before mixing it into the buttercream.

Tips for Perfect Salted Caramel Buttercream Frosting

• Always start with room temperature butter for the smoothest texture.
• Sift the powdered sugar to prevent lumps.
• Use high-quality caramel sauce — it really makes a difference in flavor.
• Don’t skip the final pinch of sea salt; it gives the frosting its signature taste.
• If piping, chill the frosting slightly to help it hold its shape better.

---

Watch Out for These Mistakes While Cooking

• Using warm caramel: It can melt the butter and ruin the consistency.
• Overbeating: Once everything is combined, don’t overmix or the frosting can become too airy or break.
• Wrong butter temperature: Cold butter won’t whip properly; melted butter will make it greasy.
• Too much salt: If using regular salt instead of flakes, reduce the quantity. It’s easy to overdo.
• Skipping the taste test: Always taste before final use to balance sweetness and salt.
