This Smooth Brown Sugar Buttercream Frosting is sweet, creamy, and absolutely delicious! Soft brown sugar is perfectly mixed into the frosting with no grainy texture making it perfect for frosting your favorite cakes and cupcakes!
When I was in pastry school, I absolutely loved working with brown sugar! Brown sugar is different than white or confectioners sugar because it has molasses added to it. It’s what gives it the brown color!
It also adds more moisture than white sugar and has a light natural caramel-like flavor that makes it perfect for homemade buttercream frosting!
You can use this frosting to top chocolate cake, vanilla cupcakes, or even caramel chocolate chip cookies!
If you need more frostings, be sure to make my other buttercream frosting flavors like strawberry buttercream, lemon buttercream, raspberry buttercream, and coffee buttercream frosting.

INGREDIENTS NEEDED
- Brown Sugar – You can use either light or dark brown sugar to make this frosting depending on how you like the taste.
- Water – Used to make the brown sugar simple syrup to give it a pourable consistency.
- Unsalted Butter – Makes up the base of the buttercream offering a rich and buttery flavor.
- Confectioners Sugar – Along with the brown sugar, confectioners sugar sweetens the frosting and blends in with the butter nice and smoothly.
- Salt – Helps balance the sweetness of all the sugar in the frosting.
- Milk – Helps thin out the frosting to a spreadable consistency while keeping it creamy.
HOW TO MAKE BROWN SUGAR BUTTERCREAM FROSTING
- Create brown sugar simple syrup: In a small saucepan over medium heat add the brown sugar and water. Mix slowly and stir as the sugar melts. Stir for 3-4 minutes until all the brown sugar has dissolved. Let cool or place in the fridge for 20 minutes. Do not skip the cooling process.
- Cream the butter and sugar together: Add the butter and sugar to the bowl of a stand mixer and add the paddle attachment. Bring the mixer to low speed and gradually increase to medium as the sugar begins to emulsify. After mixing for one minute, scrape down the sides with a rubber spatula.
- Add in the brown sugar syrup: To the mixture, add in the brown sugar syrup, then mix again on medium for 1-2 minutes until everything is fully mixed.
- Add in the salt and milk: To the mixing bowl, add in the salt and milk and mix for 30 seconds or until the milk and salt are fully mixed in. Use immediately or store.
TIPS FOR RECIPE SUCCESS
- Before adding the brown sugar syrup to the frosting mixture, make sure it is completely cooled as hot liquid could melt the butter and cause the frosting to not set up.
- Make sure to scrape down the sides of the bowl often to make sure all the ingredients are evenly mixed in.
- If you like your frosting thicker, add less milk. If you like it thinner, add more milk 2 teaspoons at a time until you reach the desired consistency.
- This recipe makes enough to frost 12-14 cupcakes or one 8″ 2 layer cake.
- Double the recipe if you need to frost a two-layer cake or 24 cupcakes.
- This recipe pipes well using piping bags and a star tip!
STORAGE AND FREEZING
Storing: To store outside of the fridge, keep in an airtight container at room temperature for up to one week. If storing in the fridge, keep it in an airtight container and bring it to room temperature before using it as it will thicken slightly.
Freezing: Buttercream can be frozen for up to three months if stored in an airtight container or freezer-safe bag with as much air removed as possible. Thaw overnight in the fridge and re-whip with a mixer before using.

I rarely leave comments but I must because this brown sugar buttercream is divine! Great flavor with an aftertaste that just kept on giving. Well done!!
YAY Theresa!! Thank you so much for your comment and 5 star rating, it just made my day! So glad you love this recipe!
Can this be made into a cream cheese icing with the brown sugar syrup?
Hi Alison, I havent tried it but if you make sure the syrup is very cool you can add it to cream cheese frosting and I think it would be ok!
This is absolutely delicious! I wanted a richer flavor but only had light brown sugar. So I added just 1 tsp of molasses to the syrup mixture (after removing it from heat and before cooling in the fridge). Thanks for the recipe 🙂
So glad that worked! Thanks so much for the 5 star review!!
