This white chocolate buttercream frosting is smooth, creamy, and easy to pipe with a rich but balanced white chocolate flavor. Made with real white chocolate, it’s not overly sweet and works perfectly for cakes, cupcakes, and elegant desserts.
If you’ve ever had buttercream that was too sweet, too soft, or difficult to work with, this version fixes that. It holds its shape, spreads smoothly, and gives you that clean, bakery-style finish.
Back in my cake decorating days, I was always experimenting with frostings that felt a little more elevated than basic vanilla buttercream—but still stable enough to pipe and easy to work with. This quickly became one of my go-to frostings for cakes, cupcakes, and even wedding orders.

- Smooth and stable for piping cakes and cupcakes
- Balanced sweetness (not overly sugary like traditional buttercream)

Ingredients and Substitutes
- White chocolate – Use good-quality white chocolate bars for the best flavor and smooth texture. Avoid compound chocolate if possible, as it can be overly sweet and slightly greasy.
- Heavy cream – Used to melt the chocolate smoothly and help with consistency. You can use milk, but the frosting will be slightly less rich.
- Butter – Forms the base of the buttercream. Use room temperature butter so it creams properly.
- Powdered sugar – Adds sweetness and structure. This recipe uses less sugar than traditional buttercream, so it’s not overly sweet.
- Vanilla extract – Enhances the flavor of the white chocolate.
- Salt – Balances the sweetness and improves overall flavor.
Step by step: White chocolate buttercream
1. Melt the white chocolate
Heat the cream until hot, then pour over the white chocolate. Let sit for 1 minute, then stir until smooth. Set aside to cool completely.
2. Cream the butter
Beat the butter until smooth and creamy.
3. Add powdered sugar
Add the powdered sugar gradually and beat until light and fluffy.
4. Add flavor
Mix in the vanilla and salt.
5. Add white chocolate
Once the chocolate mixture is cool, slowly add it while mixing until smooth and fully combined.
6. Adjust consistency
If needed, add a little cream to loosen or powdered sugar to thicken.
Getting the right consistency
This frosting will thicken slightly as it sits because of the white chocolate.
- Too thick → add 1 tablespoon cream at a time
- Too soft → chill for 10–15 minutes, then re-whip
Storage
- Fridge: Store in an airtight container for up to 1 week.
- Freezer: Freeze for up to 1 month. Thaw overnight in the fridge, then bring to room temperature and re-whip before using.

- Make sure the white chocolate is fully cooled before adding it to the buttercream, or it can melt the butter and cause the frosting to split.
- Butter should be soft but not greasy—if it’s too warm, the frosting will be too soft.
- This frosting is less sweet than traditional buttercream, with a more balanced white chocolate flavor.
- If the frosting becomes too soft while working, chill for 10–15 minutes, then re-whip before using.
- For the smoothest finish on cakes, mix on low speed at the end to remove excess air bubbles.

Can I add mango puree to the White Chocolate Buttercream? If so, how much? Do I need to make any additional changes? This is for a cake frosting.
You will need to replace the liquid in the recipe with mango puree. So instead of cream or milk use mango puree. How much will depend on the texture and consistency you need. Start with 1/2 cup, check consistency, then add more.
