Despite the unusually warm weather outside in PA, fall baking in my kitchen is in full swing! And what better way to add more fall flavor to your homemade baked goods than with this Cinnamon Buttercream?!

This cinnamon spice buttercream frosting is super smooth and creamy and adds a warm and cozy feeling to all of your fall baked goods.

It’s my classic small batch buttercream frosting with a hint of cinnamon added.

It originally debuted with my pumpkin sugar cookies, but you can also use it for pumpkin pie cupcakes, pumpkin cake, pumpkin poke cake, banana cupcakes, snickerdoodle cookie bars, and more.

You can even use it as a buttercream frosting for puff pastry cinnamon rolls.

And if you’re not a huge fan of apples and pumpkins, you can use it for any of my 6 inch cake recipes and small batch cupcake recipes including gingerbread cupcakes.

Ingredients For Cinnamon Buttercream

To make your cinnamon buttercream frosting, you’ll need the following ingredients:

  • Powdered sugar: Thickens the frosting so you can easily spread or pipe it.
  • Butter: Butter provides richness and creaminess (hence the name buttercream)
  • Ground cinnamon:The star of the frosting! Obviously the fresher is better, but your average ground cinnamon will do. You can also use pumpkin pie spice for even more flavor.
  • Salt: Add a pinch of salt if using unsalted butter.
  • Milk: Helps smooth out the frosting (especially if you’re using a knife to spread)
  • Vanilla extract: Adds more depth of flavor so it’s not one note

How To Make Cinnamon Frosting

Here’s how to make cinnamon buttercream:

  1. Beat together powdered sugar, butter, cinnamon, and salt until smooth and creamy then scrape down the bowl.
  2. Add milk and vanilla then beat for an additional minute. If it’s too thick, add a little more milk. If it’s not thick enough for piping, add more powdered sugar.

Can cinnamon buttercream be made in advance?

Yes, you can make cinnamon buttercream frosting in advance! Store it in an airtight container in the refrigerator for up to 3 days.

You may need to bring your frosting to room temperature if it’s too hard to spread.

Do you have to refrigerate buttercream frosting?

No, you do not need to refrigerate buttercream frosting. Because it uses a good amount of powdered sugar, it’s safe to leave out at room temperature for 2-3 days.

However, buttercream tends to melt if it’s too warm because of the butter’s melting point. In the winter I can leave my cake out, but in the summer I refrigerate my cakes.

You will also want to refrigerate your cake if you want it to last longer than 3 days.

Cinnamon Buttercream FAQ

Why is my frosting lumpy?

It’s likely your butter is too cold. Make sure you’re using room temperature butter.

Why did my frosting split?

Chances are the temperatures of your ingredients are off. Your butter is too warm and/or your cream is too cold. Warm butter + cold cream doesn’t mix well. To fix this, slightly warm up your bowl over a pan of simmering water then beat until smooth again.

Why is my frosting runny?

Your butter is too soft, you may have added too much liquid, or your kitchen is too warm. To fix this, add a little more powdered sugar to thicken it up or refrigerate for 15 minutes before using.
