This pumpkin buttercream frosting may or may not be my fall weakness (may or may not as in 100% it is). It’s so delicious that I could easily forego the baked goods and eat it with a spoon instead. Even Shane, my non-pumpkin loving husband, is obsessed. My plans to turn him into someone that loves all things pumpkin are on track thanks to this recipe.

How to make pumpkin spice buttercream frosting:

This recipe is so easy to make, it just requires a little patience. The keys to this recipe are to use room temperature unsalted butter, to sift the icing sugar (get all those clumps out!), and to beat the frosting on medium speed using your stand mixer for a few minutes (until it’s delightfully fluffy). Other than those tips, it’s pretty straightforward.

Pumpkin and butter mixed.

Once you add the pumpkin into the butter, you’ll notice it has a weird grainy texture. It’s nothing to worry about, it’s supposed to look like this at this stage. It will become smooth and beautiful, I promise!

Be sure to sift the spices into the icing sugar. We want to get every single lump out so you’re left with the most velvety texture.

I highly recommend using my DIY Pumpkin Pie Spice blend for this recipe. I’ve been using it for all of my fall baking, and it’s made everything so much more delicious, aromatic, and full of that incredible fall spice.

Finally, wait on adding in the salt and vanilla until the very end. Once the buttercream frosting is light and fluffy, add them in and mix until they’re just barely incorporated.

This recipe will keep in an airtight container in the fridge for up to one week. You can also store it in the freezer for up to three months. Let it thaw and then whip it up in your stand mixer to get it fluffy again. If it’s too thin, add in a Tablespoon or two of icing sugar to thicken it.

This buttercream tastes amazing on my Pumpkin Cake Cookies – it’s truly a match made in heaven! If you’re not sure what to use this buttercream on, I’d definitely recommend topping these cookies with it.
