Sometimes I dream about making buttercream when I’m sleeping.. it’s become that natural! It’s kind of like brushing your teeth when you’re half asleep.

How To Make Pumpkin Frosting

  1. Start by placing room temperature butter (and vegetable shortening, if using) into a mixing bowl. Beat using an electric mixer until smooth and creamy, 1 minute.
  2. Add in the pumpkin puree and pumpkin pie spice. Mix using a spatula.
  3. Add in the powdered sugar, 1 cup at a time, mixing with a spatula at first so the powered sugar doesn’t puff up everywhere. Once all of the powdered sugar is incorporated, beat the buttercream using an electric mixer, 1-2 minutes.
  4. TA DA! Pumpkin spice frosting that you can spread on pumpkin cupcakes.

Common Buttercream Problems

My buttercream is too wet and just flops over!
Solution: Add more powdered sugar, 1/2 to 1 cup at a time until the buttercream is loses that glossy look

My buttercream is too thick, it won’t easily come out of a piping bag!
Solution: Add more pumpkin puree. Since pumpkin puree is naturally moist, that will help put some moisture back into the buttercream.

Sheesh! This buttercream is dangerously good.
Solution: Put it on everything :)

Butter or Shortening in Frosting

Sometimes I use a combination of butter and shortening in my buttercream, especially if it’s hot outside. Vegetable shortening gives buttercream stability. Using vegetable shortening in buttercream will definitely prevent it from being “floppy.” If you’re having problems with your buttercream staying in beautiful swirls after you pipe it on, consider using shortening next time.

However, most of the time I make my frosting with all butter.

How Much Frosting Do I Need?

This recipe yields about 2 cups of frosting. Here’s a guide for how much frosting you’ll need for..

9×13 inch cake: 3-4 cups

12 cupcakes: this is really dependent on how much frosting you pipe onto each cupcake, about 2.5-3 cups

8 or 9 inch 3 layer cake: 6 cups

How To Store Frosting

If using the same day, store frosting in an airtight container on the counter.

To store for 2 or more days, store in an airtight container in the fridge. Place the frosting on the counter 20 minutes before using to come to room temperature. Re-whip with a mixer to bring it back to a fluffy consistency.

Pumpkin Buttercream

Yield: about 2 cups of frosting
Prep Time: 5 minutes
Total Time: 5 minutes

Pumpkin spice buttercream frosting is easy to make with 4 ingredients. Plus learn solutions to common buttercream problems and how much frosting you’ll need for cake, cupcakes, layer cakes. This is our go-to no fail pumpkin frosting recipe!

Ingredients

  • 3 sticks (1 cup) unsalted butter, room temperature
  • 1/2 cup pumpkin puree
  • 1 tsp pumpkin pie spice
  • 5-7 cups powdered sugar
  • Optional: replace 1 stick of butter with 1/2 cup vegetable shortening for a more stable frosting, especially in hot weather

Note:

  • Some have commented that they used 3 & 1/2 cups powdered sugar and liked the flavor. The amount of powdered sugar all depends on your taste and how stable you want the frosting.

Instructions

  1. Place room temperature butter (and vegetable shortening if using) in a mixing bowl. Beat using an electric mixer until smooth, 1 minute.
  2. Add in the pumpkin puree and pumpkin pie spice. Mix using a spatula.
  3. Add in the powdered sugar, 1 cup at a time, mixing with a spatula at first so the powered sugar doesn’t puff up everywhere. Once all of the powdered sugar is incorporated, beat the buttercream using an electric mixer, 1-2 minutes or until smooth.
  4. Use on your favorite desserts like pumpkin cupcakes, doctored up pumpkin cake, chocolate cupcakes, and brownies.

Notes

To frost a 6 inch 3 tier cake, double the recipe. To frost a 8 inch 3 tier cake, triple the recipe. To frost 12 cupcakes, you could get by with the original recipe, otherwise increase the recipe by half. To frost 24 cupcakes, double the recipe. I always like to err on the side of having leftover buttercream. Plus, I pipe a lot of buttercream onto each cupcake.
